45. A decade of Condor experience at Fermilab

Steven Timm (Fermilab)

16/10/2012, 11:00

Computing & Batch Services

Presentation

The Condor Batch System has been used at Fermilab for a decade in the Run II Reprocessing and Analysis, the USCMS Tier 1 facility, and the FermiGrid General Purpose Grid Cluster. In this talk I present an overview of the operational stability, the scalabilty, and the best practices we have learned to build a 27,000 job slot campus grid using the Condor system.

19. CERN Batch System, Monitoring and Accounting

Jerome Belleman (CERN)

16/10/2012, 11:30

Computing & Batch Services

Presentation

The CERN batch service runs a 60k CPU core cluster using Platform LSF. We present some of the challenges of running a service at this scale, and describe the current planning of how we aim to evolve the current system to a more dynamic, larger scale service. As part of this, we recently undertook a project of developing new monitoring tools and upgrading the batch accounting system; we...

36. LRMS Migration at GridKa

Manfred Alef (Karlsruhe Institute of Technology (KIT))

16/10/2012, 12:00

Computing & Batch Services

Presentation

This talk describes the scheduled migration to another LRMS at GridKa: - Problems and limitations of the LRMS which is currently used at GridKa - Selection and tests of a new one - Configuration details, e.g. fair-share configurations, and experiences with a first sub-cluster which is already managed by the new LRMS

Computing & Batch Services

Presentation

CC-IN2P3 has been running OGE for more than one year now. After describing the current context, I will report the difficulties encountered, solved or not, and the new enhancements we would like to get.

18. Setting up the CSP mode in a Gridengine production cluster

Andreas Haupt (Deutsches Elektronen-Synchrotron (DE))

17/10/2012, 15:00

Computing & Batch Services

Presentation

All the currently available Gridengine implementations don't provide any authenticated access with the default setup. This opens a big and easily exploitable security hole which might be considered severe especially in multi-community clusters. This talk will describe in detail the attack vector available in such setups. It will furthermore give a step-by-step guide to activate the...

49. Slurm Experiences for WLCG in the Nordics

Erik Mattias Wadenstein (Unknown)

17/10/2012, 16:00

Computing & Batch Services

Presentation

Many compute clusters in the nordics run Slurm, this includes the grid connected ones. This talk looks at the experience, which parts works well, what could use improvements, and some comparisons to other batch systems.

43. Testing SLURM batch system for a grid farm: functionalities, scalability, performance and how it works in a GRID environment

Dr Giacinto Donvito (INFN-Bari)

17/10/2012, 16:30

Computing & Batch Services

Presentation

We will show all the work done in order to install and configure the batch system itself together with the security configuration needed. In this presentation we will show the results of the deep testing that we have done on SLURM, in order to be sure that it will cover all the needed functionalities like: priorities, fairshare, limits, QoS, failover capabilities and others. We will report...
