-Introducing the sixth annual report of CNAF...
+\small The first months of 2018 were still affected by the effects of the flooding suffered in November 2017 and it was only in March 2018 
+that our data center was able to resume its full activity. 
+Despite this, the overall performance of the Tier 1 for the LHC experiments and for the many other astroparticle and nuclear physics experiments was very good, 
+and enough to place CNAF's Tier 1 among the most productive ones in the WLCG ecosystem, as the reports of the experiments in this document show. 
+Even the activities of both the HPC clusters and the Cloud@CNAF infrastructure resumed regular operations after the systems have been brought back to CNAF 
+from the sites that had temporarily hosted them.
+
+The flooding had indeed beneficial repercussions in speeding up the decision to find a new location for our data center. 
+The move was already planned in order to face the challenges of High-Luminosity LHC and of the astroparticle experiments that will begin their data acquisition 
+in the second half of 2020, but the dramatic event of November 2017 made the fragility and weaknesses of the current installation clear. 
+
+Also, during 2018 three events have matured paving the way for the definition of a development strategy towards both a new site and a new computing model, 
+that includes the possibility to exploit the computing power of the HPC systems: the availability of a big area such as Bologna Tecnopolo where to install 
+our new data center; the possibility of a joint upgrade together with the Italian supercomputing center CINECA thanks to European and Italian funding; 
+the additional funds from the Italian Government for a project aimed at strengthening the INFN computing infrastructures.
+
+Our R\&D activities have proceeded regularly, meeting the expected milestones and deliverables. 
+In particular, the path towards a European Open Science Cloud (EOSC) has seen significant progress thanks to the EOSCHub and EOSCPilot projects, 
+in both of which CNAF plays an important role. Contributions to the EOSC have also come from other H2020 projects in which we are involved, 
+namely XDC-eXtreme Data Cloud, which focuses mainly on data management services evolved for a context of distributed resources, 
+and DEEP-Hybrid DataCloud, which addresses the need to support intensive computing techniques, requiring specialized HPC hardware, 
+to explore very large data sets.
+
+The External Projects and Technology Transfer (PETT) Organizational Unit has contributed to various projects in the field of computing,
+communication of science, technology transfer and education. Great effort has been dedicated to the consolidation of the Technology Transfer Laboratory (INFN-TTLab), 
+a collaboration between CNAF and the INFN divisions of Bologna and Ferrara with the goal of promoting the transfer of our know-how towards regional enterprises. 
+2018 has also been the first full year in which the TTLab operated an ISO-27001 ISMS consisting of a subset of the Data Center resources. 
+Such certification, which was acquired in order to be qualified for storing and managing sensitive data, 
+could open new opportunities of exploitation of our resources in the next future. 
+
+Also noteworthy is the involvement of CNAF in the INFN Cultural Heritage Network (CHNet), 
+where our expertise in Cloud technologies and software development is put to good use for the preparation of a digital library 
+where members of the network can safely store their datasets and have access to applications for their processing. 
+
+This report about the accomplishments of CNAF during 2018 arrives just at the end of 2019. 
+The delay is due to higher-priority commitments that have overlapped with its finalization, 
+but we are well aware that such situation affects its usefulness as a means of transparency towards our stakeholders 
+and of recognition of the hard work and dedication of the personnel of the Center. 
+To prevent similar situations in the future we are adopting some corrections to the editing process 
+already for the report about the year 2019, and we are also planning some interesting surprises that we hope will please our readers.

+\author{Stefano Dal Pra$^1$}

+\begin{abstract}
+  The Tier 1 data center provides computing resources for a variety of HEP and
+  Astrophysics experiments, organized in Virtual Organization submitting their
+  jobs to our computing facilities through Computing Elements, acting as Grid
+  interfaces to the Local Resource Manager. We planned to phase--out our
+  current LRMS (IBM/Platform LSF 9.1.3) and CEs (CREAM) to adopt HTCondor as a
+  replacement of LSF and HTCondor--CE instead of CREAM. A small cluster has
+  been set up to practice the management and evaluate a migration plan to a
+  new LRMS and CE set. This document reports about our early experience on
+  this. 
+\end{abstract}
+
+\section{Introduction}
+
+The INFN-Tier 1 currently provides a computing power of about 400 kHS06, 35000
+slots on one thousand physical Worker Nodes. These resources are accessed
+through Grid by 24 Grid VOs and locally by 25 user groups.
+
+The IBM/Platform LSF 9.1.3 batch system arbitrate access to all the competing
+users groups, both Grid and local, according to a \tmtextit{fairshare} policy,
+designed to prevent underutilization of the available resources or starvation
+of lower priority groups, while ensuring a medium--term share proportional to
+configured quotas.
+
+The CREAM--CEs act as frontend for Grid users to the underlying LSF batch
+system, submitting their jobs on behalf of them. This setup has proven to be
+an effective solution for several years. However, the compatibility between
+CREAM and HTCondor seems to be less tight than with LSF. Moreover, active
+development of CREAM has recently ceased and thus we cannot expect new
+versions to be released, nor better HTCondor support to be implemented by an
+official development team. We decided to migrate our batch system solution
+from LSF to HTCondor, thus we need to also change our CEs. We have selected
+HTCondor-CE as a natural choice, because it is maintained by the same
+development team of HTCondor. In the following we provide a report about our
+experience with HTCondor and HTCondor--CE.
+
+\section{The HTCondor cluster}
+
+To get acquainted with the new batch system and CEs, to evaluate how these can
+work together, how other components, such as monitoring, provisioning and
+accounting systems can be integrated with HTCondor and HTCondor--CE and
+finally to devise a reasonable migration plan, a simple small HTCondor 8.6.13
+cluster has been set up during spring 2018. A HTCondor--CE was soon added, in
+late April. HTCondor is a very mature opensource product, deployed at several
+major Tier 1 for years, thus we already know that it will certainly fit our
+use cases. The HTCondor--CE, on the other hand, is a more recent product, and
+a number of issues might be too problematic for us to deal with. Our focus is
+about ensuring that this CE implementation can be a viable solution for us.
+
+\subsection{The testbed}
+
+The test cluster consists of:
+\begin{itemizedot}
+  \item a HTCondor--CE on top of
+  
+  \item a HTCondor \ Central Manager and Collector
+  
+  \item 3 Worker Nodes (Compute Nodes, in HTCondor terms), 16 slot each.
+\end{itemizedot}
+
+\subsection{HTCondor--CE Installation and setup}
+
+The first CE installation was a bit tricky. The RPMs were available from OSG
+repositories only, meaning that a number of default settings and dependencies
+were unmet for EGI standards. Short after, however, HTCondor--CE RPMs were made
+available on the same official repository of HTCondor.
+
+\subsubsection{Setup}
+
+To setup the configuration for the HTCondor and HTCondor--CE, puppet modules
+are available. Unfortunately the puppet system at our site is not compatible
+with these modules as they depend on \tmtextit{hiera}, which is not supported
+at our site. These were later adapted to make them compatible with our
+configuration management system. In the meanwhile, the setup was finalized
+looking at the official documentation.
+
+\subsubsection{Configuration}
+
+The first configuration was completed manually. The main documentation
+source for the HTCondor--CE is that of the OSG website~\cite{OSGDOC},
+which refers to a tool \tmtextit{osg-configure} not present on the
+general HTCondor--CE release.  Because of this, the setup was completed
+by trial and error. Once a working setup was obtained, a set of
+integration notes were added to a public wiki~\cite{INFNWIKI}.  This
+should help other non OSG users to get some supplementary hint to
+complete their installation.
+
+\subsubsection{Accounting}
+
+As of 2018, the official EGI accounting tool, APEL~\cite{APEL}, has no support for
+HTCondor--CE. On the other hand, INFN--T1 has a custom accounting tool in
+place for several years now~\cite{DGAS}. Thus, it's all about finding a suitable way to
+retrieve from HTCondor the same information that we retrieve from CREAM--CE
+and LSF.
+
+A working way to do so has been by using python and the \tmtextit{python
+bindings}, a set of api interfaces to the HTCondor daemons. These can be used
+to query the SCHEDD at the CE and retrieve a specified set of data\quad about
+recently finished jobs, which are subsequently inserted to our local
+accounting database. A noticeable fact to note, is that the grid information
+(User DN, VO, etc.) are directly available together with all the needed
+accounting data. This simplifies the accounting problem, as it is no more
+necessary to collect grid data separately from the BLAH component and then
+look for matches with the corresponding grid counterpart.
+
+This solution have been used during 2018 to provide accounting for
+HTCondor--CE testbed cluster.
+
+\subsection{Running HTCondor--CE}
+
+After some time to become confident with the main configuration tasks, the
+testbed begun working with jobs submitted by the 4 LHC experiments from
+September 2018. The system proved to be stable and smooth, being able to work
+unattended. This confirms that this system can be a reliable substitute for
+CREAM--CE and LSF.
+
+\subsection{Running HTCondor}
+
+The HTCondor batch system is a mature product with a large user base. We have
+put less effort at investigating it deeply. We already know that most or all
+of needed features will work well. Rather, some effort have been put on
+dealing with configuration management.
+
+\subsubsection{Configuration management}
+
+Eventhoutgh a standard base of puppet classes have been adapted to our
+management system, an additional python tool have been written to improve
+flexibility and readiness. The tool works by reading and enforcing on each
+node of the cluster a set of configuration directives written on text files
+accessible from a shared filesystem. The actual set and the read order depends
+on the host role and name. Doing so, a large cluster can be quite easily
+managed as a collection of set of host sets. The tool is quite simple and
+limited but it can be improved as needed when more complex requirements should
+arise.
+
+\subsection{The migration plan}
+
+After using the testbed cluster a possible plan for a smooth migration have
+been devised:
+\begin{itemizedot}
+  \item Install and setup a new HTCondor cluster, with a few more HTCondor--CE
+  and an initial small set of Worker Nodes
+  \item Enable the LHC VOs on the new cluster
+  \item Add more WN to the new cluster gradually
+  \item Enable other Grid VOs
+  \item Finally, enable submission from local submissions. These are made from
+  a heterogenous set of users, with a potentially rich set of individual needs
+  and can require a considerable administrative effort to meet all of them.
+\end{itemizedot}
+
+\subsection{Conclusion}
+
+A testbed cluster based on HTCondor--CE on top of HTCondor batch system has
+been deployed to evaluate these as a substitute for CREAM--CE and LSF. The
+evaluation has mostly focused on the HTCondor--CE, as it is the most recent
+product. Apart for a few minor issues, mainly related to gaps in the available
+documentation, the CE proved to be a stable component. The possibility to
+perform accounting has been verified.

+\section{Introduction}
+
+   
+ATLAS \cite{ATLAS-det} is one of two general-purpose detectors at the Large Hadron Collider (LHC). It investigates a wide range of physics, from the search for the Higgs boson and standard model studies to extra dimensions and particles that could make up dark matter. Beams of particles from the LHC collide at the center of the ATLAS detector making collision debris in the form of new particles, which fly out from the collision point in all directions. Six different detecting subsystems arranged in layers around the collision point record the paths, momentum, and energy of the particles, allowing them to be individually identified. A huge magnet system bends the paths of charged particles so that their momenta can be measured. The interactions in the ATLAS detectors create an enormous flow of data. To digest the data, ATLAS uses an advanced trigger system to tell the detector which events to record and which to ignore. Complex data-acquisition and computing systems are then used to analyse the collision events recorded. At 46 m long, 25 m high and 25 m wide, the 7000-tons ATLAS detector is the largest volume particle detector ever built. It sits in a cavern 100 m below ground near the main CERN site, close to the village of Meyrin in Switzerland.
+More than 3000 scientists from 174 institutes in 38 countries work on the ATLAS experiment.
+ATLAS has been taking data from 2010 to 2012, at center of mass energies of 7 and 8 TeV, collecting about 5 and 20 fb$^{-1}$ of integrated luminosity, respectively. During the complete Run-2 phase (2015-2018) ATLAS collected and registered at the Tier 0 147 fb$^{-1}$ of integrated luminosity at center of mass energies of 13 TeV.
+The experiment has been designed to look for New Physics over a very large set of final states and signatures, and for precision measurements of known Standard Model (SM) processes. Its most notable result up to now has been the discovery of a new resonance at a mass of about 125 GeV \cite{ATLAS higgs}, followed by the measurement of its properties (mass, production cross sections in various channels and couplings). These measurements have confirmed the compatibility of the new resonance with the Higgs boson, foreseen by the SM but never observed before.
+
+
+
+\section{The ATLAS Computing System}
+
+ 
+ 
+ The ATLAS Computing System \cite{ATLAS-cm} is responsible for the provision of the software framework and services, the data management system, user-support services, and the world-wide data access and job-submission system. The development of detector-specific algorithmic code for simulation, calibration, alignment, trigger and reconstruction is under the responsibility of the detector projects, but the Software and Computing Project plans and coordinates these activities across detector boundaries. In particular, a significant effort has been made to ensure that relevant parts of the “offline” framework and event-reconstruction code can be used in the High Level Trigger. Similarly, close cooperation with Physics Coordination and the Combined Performance groups ensures the smooth development of global event-reconstruction code and of software tools for physics analysis.
+
+\subsection{The ATLAS Computing Model}
+The ATLAS Computing Model embraces the Grid paradigm and a high degree of decentralisation and sharing of computing resources. The required level of computing resources means that off-site facilities are vital to the operation of ATLAS in a way that was not the case for previous CERN-based experiments. The primary event processing occurs at CERN in a Tier 0 Facility. The RAW data is archived at CERN and copied (along with the primary processed data) to the Tier 1 facilities around the world. These facilities archive the raw data, provide the reprocessing capacity, provide access to the various processed versions, and allow scheduled analysis of the processed data by physics analysis groups. Derived datasets produced by the physics groups are copied to the Tier 2 facilities for further analysis. The Tier 2 facilities also provide the simulation capacity for the experiment, with the simulated data housed at Tier 1 centers. In addition, Tier 2 centers provide analysis facilities, and some provide the capacity to produce calibrations based on processing raw data. A CERN Analysis Facility provides an additional analysis capacity, with an important role in the calibration and algorithmic development work. ATLAS has adopted an object-oriented approach to software, based primarily on the C++ programming language, but with some components implemented using FORTRAN and Java. A component-based model has been adopted, whereby applications are built up from collections of plug-compatible components based on a variety of configuration files. This capability is supported by a common framework that provides common data-processing support. This approach results in great flexibility in meeting both the basic processing needs of the experiment, but also for responding to changing requirements throughout its lifetime. The heavy use of abstract interfaces allows for different implementations to be provided, supporting different persistency technologies, or optimized for the offline or high-level trigger environments.
+The Athena framework is an enhanced version of the Gaudi framework that was originally developed by the LHCb experiment, but is now a common ATLAS-LHCb project. Major
+design principles are the clear separation of data and algorithms, and between transient (in-memory) and persistent (in-file) data. All levels of processing of ATLAS data, from high-level trigger to event simulation, reconstruction and analysis, take place within the Athena framework; in this way it is easier for code developers and users to test and run algorithmic code, with the assurance that all geometry and conditions data will be the same for all types of applications ( simulation, reconstruction, analysis, visualization).
+One of the principal challenges for ATLAS computing is to develop and operate a data storage and management infrastructure able to meet the demands of a yearly data volume of O(10PB) utilized by data processing and analysis activities spread around the world.  The ATLAS Computing Model establishes the environment and operational requirements that ATLAS data-handling systems must support and provides the primary guidance for the development of the data management systems.
+The ATLAS Databases and Data Management Project (DB Project) leads and coordinates ATLAS activities in these areas, with a scope encompassing technical data bases (detector production, installation and survey data), detector geometry, online/TDAQ databases, conditions databases (online and offline), event data, offline processing configuration and bookkeeping, distributed data management, and distributed database and data management services. The project is responsible for ensuring the coherent development, integration and operational capability of the distributed database and data management software and infrastructure for ATLAS across these areas.
+The ATLAS Computing Model defines the distribution of raw and processed data to Tier 1 and Tier 2 centers, so as to be able to exploit fully the computing resources that are made available to the Collaboration. Additional computing resources are available for data processing and analysis at Tier 3 centers and other computing facilities to which ATLAS may have access. A complex set of tools and distributed services, enabling the automatic distribution and processing of the large amounts of data, has been developed and deployed by ATLAS in cooperation with the LHC Computing Grid (LCG) Project and with the middleware providers of the three large Grid infrastructures we use: EGI, OSG and NorduGrid. The tools are designed in a flexible way, in order to have the possibility to extend them to use other types of Grid middleware in the future.
+The main computing operations that ATLAS have to run comprise the preparation, distribution and validation of ATLAS software, and the computing and data management operations run centrally on Tier 0, Tier 1 sites and Tier 2 sites. The ATLAS Virtual Organization allows production and analysis users to run jobs and access data at remote sites using the ATLAS-developed Grid tools.
+The Computing Model, together with the knowledge of the resources needed to store and process each ATLAS event, gives rise to estimates of required resources that can be used to design and set up the various facilities. It is not assumed that all Tier 1 sites or Tier 2 sites are of the same size; however, in order to ensure a smooth operation of the Computing Model, all Tier 1 centers usually have broadly similar proportions of disk, tape and CPU, and similarly for the Tier 2 sites.
+The organization of the ATLAS Software and Computing Project reflects all areas of activity within the project itself. Strong high-level links are established with other parts of the ATLAS organization, such as the TDAQ Project and Physics Coordination, through cross-representation in the respective steering boards. The Computing Management
+Board, and in particular the Planning Officer, acts to make sure that software and computing developments take place coherently across sub-systems and that the project as a whole meets its milestones. The International Computing Board assures the information flow between the ATLAS Software and Computing Project and the national resources and their Funding Agencies.

+\section{The role of the Italian Computing facilities in the global ATLAS Computing}
+
+Italy provides Tier 1, Tier 2 and Tier 3 facilities to the ATLAS collaboration. The Tier 1, located at CNAF, Bologna, is the main center, also referred as “regional” center. The Tier 2 centers are distributed in different areas of Italy, namely in Frascati, Napoli, Milano and Roma. All 4 Tier 2 sites are considered as Direct Tier 2 (T2D), meaning that they have an higher importance with respect to normal Tier 2s and can have primary data too. They are also considered satellites of the Tier 1, also identified as nucleus. The total of the Tier 2 sites corresponds to more than the total ATLAS size at the Tier 1, for what concerns disk and CPUs; tape is not available in the Tier 2 sites. A third category of sites is the so-called Tier 3 centers. Those are smaller centers, scattered in different places in Italy, that nevertheless contributes in a consistent way to the overall computing power, in terms of disk and CPUs. The overall size of the Tier 3 sites corresponds roughly to the size of a Tier 2 site. The Tier 1 and Tier 2 sites have pledged resources, while the Tier 3 sites do not have any pledge resource available.
+In terms of pledged resources, Italy contributes to the ATLAS computing as 9\% of both CPU and disk for the Tier 1. The share of the Tier 2 facilities corresponds to 7\% of disk and 9\% of CPU of the whole ATLAS computing infrastructure. The Italian Tier 1, together with the other Italian centers, provides both resources and expertise to the ATLAS computing community, and manages the so-called Italian Cloud of computing. Since 2015 the Italian Cloud does not only include Italian sites, but also Tier 3 sites of other countries, namely South Africa and Greece.
+The computing resources, in terms of disk, tape and CPU, available in the Tier 1 at CNAF have been very important for all kind of activities, including event generation, simulation, reconstruction, reprocessing and analysis, for both MonteCarlo and real data. Its major contribution has been the data reprocessing, since this is a very I/O and memory intense operation, normally executed only in Tier 1 centers. In this sense CNAF has played a fundamental role for the fine measurement of the Higgs [3] properties in 2018 and other analysis. The Italian centers, including CNAF, have been very active not only in the operation side, but contributed a lot in various aspect of the Computing of the ATLAS experiment, in particular for what concerns the network, the storage systems, the storage federations and the monitoring tools. The Tier 1 at CNAF has been very important for the ATLAS community in 2018, for some specific activities:
+
+\begin{itemize}
+\item improvements on the WebDAV/HTTPS access for StoRM, in order to be used as main renaming method for the ATLAS files in StoRM and for http federation purposes;
+\item improvements of the dynamic model of the multi-core resources operated via the LSF resource management system and simplification of the PanDA queues, using the Harvester service to mediate the control and information flow between PanDA and the resources.
+\item network troubleshooting via the Perfsonar-PS network monitoring system, used for the LHCONE overlay network, together with the other Tier 1 and Tier 2 sites;
+\item planning, readiness testing and implementation of the HTCondor batch system for the farming resources management.
+\end{itemize}
+
+\section{Main achievements of ATLAS Computing centers in Italy}
+
+The Italian Tier 2 Federation runs all the ATLAS computing activities in the Italian cloud supporting the operations at CNAF, the Italian Tier 1 center, and the Milano, Napoli, Roma1 and Frascati Tier 2 sites. This insures an optimized use of the resources and a fair and efficient data access.  The computing activities of the ATLAS collaboration have been constantly carried out over the whole 2018, in order to analyse the data of the Run-2 and produce the Monte Carlo data needed for the 2018 run.
+ 
+The LHC data taking started in April 2018 and, until the end of the operation in December 2018, all the Italian sites, the CNAF Tier 1 and the four Tier 2 sites, have been involved in all the computing operations of the collaboration: data reconstruction, Monte Carlo simulation, user and group analysis and data transfer among all the sites. Besides these activities, the Italian centers have contributed to the upgrade of the Computing Model both from the testing side and the development of specific working groups. ATLAS collected and registered at the Tier 0 ~60.6 fb$^{-1}$ and ~25 PB of raw and derived data, while the cumulative data volume distributed in all the data centers in the grid was of the order of ~80 PB. The data has been replicated with an efficiency of 100\% and an average throughput of the order of ~13 GB/s during the data taking period, with peaks above 25 GB/s. For just Italy, the average throughput was of the order of 800 MB/s with peaks above 2GB/s. The data replication speed from Tier 0 to the Tier 2 sites has been quite fast with a transfer time lower than 4 hours. The average number of simultaneous jobs running on the grid has been of about 110k for production (simulation and reconstruction) and data analysis, with peaks over 150k, with an average CPU efficiency up to more than 80\%. The use of the grid for analysis has been stable on ~26k simultaneous jobs, with peaks around the conferences’ periods to over 40k, showing the reliability and effectiveness of the use of grid tools for data analysis.
+ 
+The Italian sites contributed to the development of the Xrootd and http/webdav federation. In the latter case the access to the storage resources is managed using the http/webdav protocol, in collaboration with the CERN DPM team, the Belle2 experiment, the Canadian Corporate Cloud ant the RAL (UK) site. The purpose is to build a reliable storage federation, alternative to the Xrootd one, to access physics data both on the grid and on cloud storage infrastructures (like Amazon S3, MicroSoft Azure, etc). The Italian community is particularly involved in this project and the first results have been presented to the WLCG collaboration.
+ 
+The Italian community also contributes to develop new tools for distributed data analysis and management. Another topic of interest is the usage of new computing technologies: in this field the Italian community contributed to the development and testing of muon tracking algorithms in the ATLAS High Level Trigger, using GPGPU. Other topics in which the Italian community is involved are the Machine Learning/Deep Learning for both analysis and Operational Intelligence and their applications to the experiment software and infrastructure, by using accelerators like GPGPU and FPGAs.
+ 
+The contribution of the Italian sites to the computing activities in terms of processed jobs and data recorded has been of about 9\%, corresponding to the order of the resource pledged to the collaboration, with very good performance in term of availability, reliability and efficiency. All the sites are always in the top positions in the ranking of the collaboration sites.
+ 
+Besides the Tier 1 and Tier 2 sites, in 2018 also the Tier 3 sites gave a significant contribution to the Italian physicists community for the data analysis. The Tier 3 centers are local farms dedicated to the interactive data analysis, the last step of the analysis workflow, and to the grid analysis over small data sample. Several italian groups set up a farm for such a purpose in their universities and, after a testing and validation process performed by the distributed computing team of the collaboration, all have been recognized as official Tier 3s of the collaboration.

+\section{Impact of CNAF flooding incident on ATLAS computing activities}
+
+
+
+The ATLAS Computing Model was designed to have a sufficient redundancy of the available resources in order to tackle emergency situations like the flooding occurred on November 9th 2017 at CNAF.  Thanks to the huge effort of the whole community of the CNAF,  the operativity of the data center restarted gradually from the second half of February 2018. A continuous interaction between ATLAS distributed computing community and CNAF people was needed to bring the computing operation fully back to normality. The deep collaboration was very successful and after one month the site was almost fully operational and the ATLAS data management and processing activities were running smoothly again. Eventually, the overall impact of the incident was limited enough, mainly thanks to the relatively quick recovery of the CNAF data center and to the robustness of the computing model.
