Computing & Batch Services

A short introduction and status report

53. Integrating HPC and HTC at BNL -- a year later

Dr Tony Wong (Brookhaven National Laboratory)

18/10/2017, 09:30

Computing & Batch Services

This presentation discusses the new responsibilities of the Scientific Data & Computing Center (SDCC) in high-performance computing (HPC) and how we are leveraging effort and resources to improve BNL community's access to local and leadership-class facilities (LCF's).

51. Techlab update

Romain Wartel (CERN)

Computing & Batch Services

Techlab is a CERN IT activity aimed at providing facilities for studies improving the efficiency of the computing architecture and making better utilisation of the processors available today.
It enables HEP experiments, communities and project to gain access to machines of modern architectures, for example Power 8, GPUs and ARM64 systems.
The hardware is periodically updated based on community...

52. HEPiX Benchmarking Working Group - Status Report October 2017

Manfred Alef (Karlsruhe Institute of Technology (KIT))

Computing & Batch Services

The HEPiX Benchmarking Working Group has worked on a fast benchmark to estimate the compute power provided job slot or a IaaS VM. The Dirac Benchmark 2012 (DB12) is scaling well with the performance at least of Alice and LHCb when running within a batch job. Now the group has started the development of a next generation long running benchmark as a successor of the current HS06 metric.

85. Running Jobs Everywhere: an Overview of Batch Services at CERN

Jerome Belleman (CERN)

18/10/2017, 11:15

Computing & Batch Services

Batch services at CERN have diversified such that computing jobs can
be run everywhere, from traditional batch farms, to disk servers, to
people's laptops, to commercial clouds. This talk offers an overview
of the technologies and tools involved.

3. Migration from Grid Engine to HTCondor

Thomas Finnern (DESY)

Computing & Batch Services

The migration of the local batch system BIRD required the
adaptation of different properties like the Kerberos / AFS support, the
automation of various operational tasks and the user and project access. The
latter includes, inter alia, fairshare, accounting and resource access. For
this, some newer features of HTCondor had to be used. We are close to the
user release. Building common...

49. Migrating a WLCG tier-2 to a Cray XC-50 at CSCS-LCG2

Francesco Giovanni Sciacca (Universitaet Bern (CH))

18/10/2017, 11:50

Computing & Batch Services

Founded in 1991, CSCS, the Swiss National Supercomputing Centre, develops and provides the key supercomputing capabilities required to solve important problems to science and/or society. The centre enables world-class research and provides resources to academia, industry and the business sector. Through an agreement with CHIPP, the Swiss Institute of Particle Physics, CSCS hosts a WLCG tier-2...

44. Optimising the resource needs for the LHC computing: ideas for a common approach

Andrea Sciaba (CERN)

18/10/2017, 12:15

Computing & Batch Services

The increase of the scale of LHC computing expected for Run 3 and even more so for Run 4 (HL-LHC) over the course of the next 10 years will most certainly require radical changes to the computing models and the data processing of the LHC experiments. Translating the requirements of the physics programme into resource needs is an extremely complicated process and subject to significant...
