WLCG GDB organized a meeting last March about batch systems. With an audience mostly from grid sites, it has been a successful review of the main batch systems used in the community by sites with concrete experience. This presentation will summarize what was presented and the main conclusions of this meeting.

It’s been almost a year since we first started running ATLAS and CMS production jobs at RAL using HTCondor, and 6 months since we fully migrated from Torque/Maui. This talk will discuss our experience so far and future plans.

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...

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...

Current Linux distributions including support for a new kernel enhancement called control groups (cgroups).
This talk is about how Univa Grid Engine integrates the Linux cgroup subsystems for better
resource isolation, utilization, and limitation in the job execution and resource allocation context. Example configurations and use cases for today's NUMA compute nodes are discussed.

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...

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...

The RACF has evaluated the Intel Ivybridge and AMD Opteron cpu's before an anticipated purchase of Linux servers for its RHIC and USATLAS programs in 2014. Price performance considerations are no longer sufficient as we must consider long-term power, cooling and space capacities in the data center. This presentation describes how these long-term considerations are increasingly altering...

At INFN-T1 we are facing the problem of TCO of computing nodes, which count for the bigger part of our electricity bill.
Intel recently introduced the Avoton SOC, targeted on the microserver, entry communication infrastructure and cloud storage market. We benchmarked this CPU and evaluated the possible adoption of this technology in our computing farm.
