        Status report from Tokyo Tier-2 for the one year operation after whole scale system upgrade 15m
        The Tokyo Tier-2, which is located at International Center for Elementary Particle Physics (ICEPP) in the University of Tokyo, was established as a regional analysis center in Japan for the ATLAS experiment. The official operation with WLCG was started in 2007 after the several years’ development since 2002. In December 2012, we have replaced almost all hardware as the third system upgrade to deal with analysis for further growing data of the ATLAS experiment. The number of CPU cores are increased by a factor of two from the previous system (9984 cores including CPUs for service instance), and the performance of individual CPU core is improved by 20 % according to the HEPSPEC06 benchmark test at 32bit compile mode. The score is estimated as 18.03 per core under Scientific Linux 6 by using Intel Xeon E5-2680 2.70 GHz. As of February 2013, 2560 CPU cores and 2.00 PB of disk storage have already been deployed for ATLAS. They have been operated stably with 95% availability in one year operation after the system upgrade. Since the number of CPU cores in the new worker node was increased from 8 cores to 16 cores, the local I/O performance for the data staging area might become a possible bottleneck for the job throughput. We have evaluated the performance by making a special worker node, which have a SSD for the local storage, at the mixture situation of running real ATLAS production jobs and analysis jobs. In consequence, we could confirm that SAS-HDD attached with nominal worker nodes at Tokyo Tier-2 is not a bottleneck for the long batch type jobs at least for the situation of 16 jobs running concurrently in one node. In this report, we would like to introduce several results of the evaluation of the local I/O performance with some experiences on the site operation.

        The talk will discuss the problems which arise from managing and distributing secrets like root passwords, keytabs, certificates in a large site. Secrets are needed in the process of installing and administrating of compute and storage systems. They should be accessible by authorized admins and from the system they belong to. There should be a way to audit the information to enforce the policies from your security department. For example quality and lifetime of passwords. In the presentation we will describe the workflows at DESY/Hamburg and show systems we use today and their deficits. Then we will describe our upcoming solution, and threats we still see.

        Future of Batch Processing at CERN 25m
        The CERN Batch System is comprised of 4000 worker nodes. 60 queues offer a service for various types of large user communities. In light of the recent developments driven by the Agile Infrastructure and the more demanding processing requirements, the Batch System will be faced with increasingly challenging scalability and flexibility needs. Last year the CERN Batch Team has started to evaluate three candidate batch systems: SLURM, HTCondor and GridEngine. This year as we are reaching a conclusion, one of our candidates is HTCondor. In this talk we give a short reminder of our requirements and our preliminary results from last year. Then we'll focus on HTCondor, our experience with it thus far, our testing framework and the results of our performance tests. Finally, we give a summary of the foreseeable challenges we would have to face if we decide to migrate the CERN Batch Service to Condor.

        The Art of Running HTCondor as a batch system 25m
        HTCondor is a well known platform for distributed high-throughput computing and often resembles a the Swiss-Army-knife of computing - there's a bit of something for everyone. With a user manual weighing in at about 1,100 printed pages, there's no wonder that sysadmins can overlook some of the most exciting features. This presentation will be dedicated to uncovering the hidden gems for running HTCondor as a batch system - useful features that are well-hidden, under-appreciated, or very recently added. This broad overview will include topics in worker node resource management, scripting, monitoring, deployment, and debugging the system.

        CC IN2P3 experience with Univa Grid Engine 25m
        After 20 years using a home made batch system named BQS (Batch Queuing System), CC-IN2P3 decided to move to Grid Engine in order to offer the scalability and robustness needed for multi-experiment production, HEP et non HEP. The site migrated from BQS to Oracle Grid Engine in 2011, then switched to Univa’s version after only two years, in June 2013. The talk presents the assessment of the change from Oracle to Univa and gives an overview of the configuration equilibrating user requirements and constraints of the site’s infrastructure, especially for multi-core jobs. Finally, plans for the deployment of new features are shown and requests to Univa are explained.

        Scheduling of multicore jobs 25m
        Nowadays, the Worldwide LHC Computing Grid consists of multi and manycore CPUs. A lot of work is undertaken by the experiments and the HEP community, in order to use these resources more efficiently. As a result, the parallelization of applications has been the main goal so far in order to allow a parallel execution of jobs. However, experiments must also consider how to schedule multicore jobs within the Computing Grid. Taking into account the trend of going towards manycore architectures, tasks might not scale sufficiently well on large number of cores. Since non linear speedup can drastically decrease overall throughput, a scheduler must define the best degree of parallelism for each job. The aim of the presentation is to define the scheduling problem and to present algorithms to solve it. Related problems, like estimation of job runtimes, will be also discussed.

        WLCG perfSONAR-PS Update 25m
        As reported at the last HEPiX meeting, the WLCG has been supporting the deployment of perfSONAR-PS Toolkit instances at all WLCG sites over the last year. The WLCG perfSONAR-PS Deployment Task Force has now wrapped up its work in April 2014. The perfSONAR network monitoring framework was evaluated and agreed as a proper solution to cover the WLCG network monitoring use cases: it allows WLCG to plan and execute latency and bandwidth tests between any instrumented endpoint through a central scheduling configuration, it allows archiving of the metrics in a local database, it provides a programmatic and a web based interface exposing the tests results; it also provides a graphical interface for remote management operations. In this presentation we will provide an update on the status of perfSONAR in WLCG and future plans for commissioning and maintaining perfSONAR in the scope of the WLCG Operations Coordination initiative and its role in supporting higher level services that are under development.

        Measuring WLCG data streams at batch job level 25m
        Batch system monitoring and related system monitoring tools allow tracking data streams at different levels. With the introduction of federated data access to the workflows of WLCG it is becoming increasingly important for data centers to understand specific data flows regarding storage element accesses, firewall configurations, or the scheduling of workflows themselves. For this purpose a proof of concept has been implemented at the GridKa Tier1 center for monitoring data streams of batch jobs. The approach aims for a direct integration into the existing batch system to enhance batch job statistics by adding continuous traffic profiles for WLCG jobs and pilots. The presentation will introduce the general concept of the developed tool and integration into the batch system as well as first results of measurements at GridKa.

        Open Compute at CERN 25m
        The Open Compute Project, OCP (http://www.opencompute.org/), was launched by Facebook in 2011 with the objective of building efficient computing infrastructures at lowest possible cost. The technologies are released as open hardware design, with the goal to develop servers and data centers following the model traditionally associated with open source software projects. In order to try out the hardware we acquired two OCP twin servers (http://hyvesolutions.com/resources/docs/2013Hyve1500Datasheet.pdf) in 2013. The servers have been tested and compared with our production hardware. Some results from this testing will be presented as well as the future plans for a possible larger deployment.

        Batch system data locality via managed caches 25m
        Modern data processing solutions increasingly rely on data locality to achieve high data access rates and scalability. In contrast the common HEP system architectures emphasis uniform resource pools with minimal locality, allowing even for cross-site data access. The concept for the new High Performance Data Analysis (HPDA) Tier3 at KIT aims at introducing data locality to HEP batch systems. Coordinating dedicated cache drives on worker nodes, existing storage hierarchies are extended into the active batch system. The presentation will illustrate the considerations of extending the classic batch architecture and showcase the planned software and hardware architecture of the HPDA T3.

        Lavoisier : a data aggregation framework 25m
        Many of us need tools for service monitoring adapted to our site specificities, or tools to do custom processing on user data. Regardless of the use-cases, we have to develop (or get developed) applications that aggregate, process and format data from heterogeneous data sources. Lavoisier (http://software.in2p3.fr/lavoisier) is a framework, which enables building such applications by assembling reusable software components (i.e. plugins). These applications can then be used through a RESTful web service API, a web interface or a command line interface with little effort. The Lavoisier framework is developed by CC-IN2P3 and used by several projects; the Operations Portal of the European Grid Infrastructure (EGI), the VAPOR portal, and some CC-IN2P3 internal tools. The presentation will give an overview of Lavoisier, and explain how it can help to easily get a maintainable, performant, robust and secure data aggregation application, while focusing on business code.

        As the Agile Infrastructure is moving forwards at CERN, more and more services are migrating to it. New tools are put in place to get the most out of its strengths while we learn lessons from the problems we hit when converting services from Quattor. At CERN, a number of services have made some significant progress in the migration to the new infrastructure; the batch service, several interactive services, CEs and VOMS are but a few examples. In this talk, we will describe some aspects of the migration process, such as virtualisation, Puppet configuration and alarming. We will discuss the strengths of the Agile Infrastructure which make running services easier, and expose the problematic areas for which we will present some of the future projects which are to address them.

        Cluster Consolidation at NERSC 25m
        This talk will provide a case study of cluster consolidation at NERSC. In 2012, NERSC began deployment of "Mendel", a 500+ node, Infiniband-attached, Linux "meta-cluster" which transparently expands NERSC production clusters and services in a scalable and maintainable fashion. The success of the software automation infrastructure behind the Mendel multi-clustering model encouraged investigation into even more aggressive consolidation efforts. This talk will detail one such effort: under the constraints of a 24x7, disruption-sensitive environment, NERSC staff merged a 400-node legacy production cluster, consisting of multiple hardware generations and ad-hoc software configurations, into Mendel's automation infrastructure. By leveraging the hierarchical management features of the xCAT software package in combination with other open-source and in-house tools, such as Cfengine and CHOS, NERSC abstracted the unique characteristics of both clusters away below a unified management interface. Consequently, both cluster components are now managed as a single, albeit complex, integrated system. Additionally, this talk will provide an update on the PDSF system at NERSC, including improvements to trending data collection and ongoing CHOS development.

        Big Data Transfer over Internet 25m
        In many cases where Big Data phenomenon is taken place there is the need to transfer the Big Data from one point of computer network to another point. Quite often those points are far away from each other. The transfer time is significant factor to transfer the Big Data. During this time the features of the data link might be changed drastically including interruptions of channel operation once or more times during data transfer. There are a number of known utilities/systems which are used for Big Data transfer. The authors investigate which utilities/systems are more suitable for Big Data transfer and which are most important architecture features for such the systems. It is of interest the comparison study of the data transfer methods. The testbed is developed to compare the data transfer utilities and study how Software Defined Networks (SDN) approach affects the Big Data transfer.

        Experiences with ATLAS and LHCb jobs in Vac virtual machines 25m
        We present experiences with running ATLAS and LHCb production jobs in virtual machines at Manchester and other sites in the UK using Vac. Vac is a self-contained VM management system in which individual hypervisor hosts act as VM factories to provide VMs contextualized for experiments, and offers an alternative to conventional CE/Batch systems and Cloud interfaces to resources. In the Vacuum model implemented by Vac, VMs appear spontaneously at sites, with contextualizations provided by the sites using templates provided by the experiments. This system takes advantage of the pilot job frameworks for managing jobs and cvmfs for managing software distribution, which together lead to these contextualizations being extremely simple in practice. Vac is implemented as a daemon, vacd, which runs on each hypervisor host. Each daemon uses a peer-to-peer UDP protocol to gather information from other Vac daemons at the site about what mix of experiment VMs are already running, and acts autonomously to decide which VMs to start using a policy given in its configuration file. The UDP protocol is also used to avoid starting VMs for experiments which have no work available, by detecting when a VM has been started recently and has stopped immediately because the pilot framework client could find no work. Vac has been running LHCb production jobs since 2013 and in 2014 a suitable ATLAS VM contextualization was developed and has been used to run ATLAS production work too. We present some preliminary comparisons of the efficiency of running LHCb and ATLAS jobs on batch worker nodes and in virtual machines using the same hardware.
