  1. 25. Operation and benchmarking of a commercial datacentre
    Peter Love (Lancaster University (GB))
    25/03/2015, 14:00
    Computing & Batch Services
    This contribution describes the usage and benchmarking of a commercial data centre running Openstack. Different cloud provisional tools are described highlighting the pros and cons of each system. A comparison is made between this facility and a standard grid T2 site in terms of job throughput and availability. Usage of the centre’s local object store is also described.

  2. 6. Remote evaluation of hardware
    Dr Tony Wong (Brookhaven National Laboratory)
    25/03/2015, 14:25
    Computing & Batch Services
    The RHIC-ATLAS Computing Facilty (RACF) at BNL has traditionally evaluated hardware on-site, with physical access to the systems. The effort to request evaluation hardware, shipping, set-up and testing has consumed an increasing amount of time and the process has become less productive over the years. To regain past productivity and shorten the evaluation process, BNL has started a pilot...

  3. 38. Evaluation of Memory and CPU usage via Cgroups of ATLAS workloads running at a Tier-2
    Gang Qin (University of Glasgow (GB))
    25/03/2015, 14:50
    Computing & Batch Services
    Modern Linux Kernels include a feature set that enables the control and monitoring of system resources, called Cgroups. Cgroups have been enabled on a production HTCondor pool sited at the Glasgow site of the UKI-SCOTGRID distributed Tier-2. A system has been put in place to collect and aggregate metrics extracted from Cgroups on all worker nodes within the Condor pool. From this...

  5. 36. Looking for a fast benchmark
    Dr Michele Michelotto (INFN Padua & CMS)
    25/03/2015, 16:05
    Computing & Batch Services
    The WLCG community has requested a fast benchmark to quickly assess the perfomances of a worker node. A good candidate is a python script used in LHCb

  6. 57. Evaluation of low power Systems on Chip for scientific computing
    Dr Lucia Morganti (INFN)
    25/03/2015, 16:30
    Computing & Batch Services
    Systems on Chip (SoCs), originally targeted for mobile and embedded technology, are becoming attractive for HEP and HPC scientific communities, given their low cost, huge worldwide shipments, low power consumption and increasing processing power - mostly associated with their GPUs. A variety of development boards are currently available, making it foreseeable to use these power-efficient...

  7. 65. A look beyond x86: OpenPOWER8 & AArch64
    Liviu Valsan (CERN)
    25/03/2015, 16:55
    Computing & Batch Services
    x86 is the uncontested leader for server platforms in terms of market share and is currently the architecture of choice for High Energy Physics applications. But as more and more importance is given to power efficiency, physical density and total cost of ownership we are seeing new processor architectures emerging and some existing ones becoming more open. With the introduction of AArch64,...

  10. 19. Batch Processing at CERN
    Jerome Belleman (CERN)
    27/03/2015, 09:00
    Computing & Batch Services
    The CERN Batch System comprises 4000 worker nodes, 60 queues and offers a service for various types of large user communities. In light of the developments driven by the Agile Infrastructure and the more demanding processing requirements, it is faced with increasingly challenging scalability and flexibility needs. This production cluster currently runs IBM/Platform LSF. Over the last...

  11. 45. Grid Engine at GridKa
    Manfred Alef (Karlsruhe Institute of Technology (KIT))
    27/03/2015, 09:25
    Computing & Batch Services
    The Grid Computing Centre Karlsruhe (GridKa) is using the Grid Engine batch system since 2011. In this presentation I will talk about the experiences with this batch system, including multi-core job support, and first experiences with cgroups.

    27/03/2015, 09:50
    Computing & Batch Services
    An update on the current status of SLURM usage in the Nordics, as well as recent developments in improving support for LHC type jobs including tuning for efficient scheduling of multicore grid jobs. Also an overview of some remaining challenges will be given together with discussion on how to address them.

  14. 31. Two years of HTCondor at the RAL Tier-1
    Andrew David Lahiff (STFC - Rutherford Appleton Lab. (GB))
    27/03/2015, 11:05
    Computing & Batch Services
    After running Torque/Maui for many years, the RAL Tier-1 migrated to HTCondor during 2013 in order to benefit from improved reliability, scalability and additional functionality unavailable in Torque. This talk will discuss the deployment of HTCondor at RAL, our experiences and the evolution of our pool over the past two years, as well as our future plans.

  15. 27. Future of Batch Processing at CERN
    Jerome Belleman (CERN)
    27/03/2015, 11:30
    Computing & Batch Services
    While we are taking measures to face the limitations discussed earlier on in our IBM/Platform LSF cluster, we have been working on setting up a new batch system based on HTCondor. There has been some progress with the pilot service which we described last HEPiX. We also went on investigating some of the more advanced functions which will lead up to the production state of the new CERN...

  16. 32. HTCondor within the European Grid and in the Cloud
    Andrew David Lahiff (STFC - Rutherford Appleton Lab. (GB))
    27/03/2015, 11:55
    Computing & Batch Services
    With the increasing interest in HTCondor in Europe, an important question for sites considering migrating to HTCondor is how well it integrates with the standard grid middleware, in particular integration with the information system and APEL accounting. Also, with the increasing interest and usage of private clouds, how easily a batch system can be integrated with a private cloud is another...

  17. 55. DrainBoss: A Drain Rate Controller for ARC/HTCondor
    Stephen Jones (Liverpool University)
    27/03/2015, 12:20
    Computing & Batch Services
    This talk describes DrainBoss, which is a proportional integral (PI) controller with conditional logic that strives to maintain the correct ratio between single-core and multi-core jobs in an ARC/HTCondor cluster. DrainBoss can be used instead of the HTCondor DEFRAG Daemon.
