At the last HEPix meeting we described the results of a proof of concept study to run batch jobs on EOS disc server nodes. By now we have moved forward towards a production level configuration and the first pre-production nodes have been setup. Beside the relevance for CERN this is also a more general step towards a hyper-converged infrastructure.

he goal of the HTCondor team is to to develop, implement, deploy, and evaluate mechanisms and policies that support High Throughput Computing (HTC) on large collections of distributively owned computing resources. Increasingly, the work performed by the HTCondor developers is being driven by its partnership with the High Energy Physics (HEP) community.
This talk will present recent changes...

PDSF, the Parallel Distributed Systems Facility, has been in continuous operation since 1996 serving high energy physics research. It is currently a tier-1 site for Star, a tier-2 site for Alice and a tier-3 site for Atlas. We are in the process of migrating PDSF workload from commodity cluster to the Cori a Cray XC40 system. The process will involve preparing containers that will allow PDSF...

The High Luminosity LHC upgrade (HL-LHC) presents new challenges and demands with a predicted 50x increase in computing needs over the next 8 to 10 years. High Performance Computing capabilities could help to equalize the computing demands due to... -

HPL and HPCG Benchmark on Brookhaven National Laboratory SDCC clusters and various generations of Linux Farm nodes has been conducted and compared with HS06 results. While HPL results are more aligned with CPU/GPU performance. HPCG results are impacted by memory performances as well.

In this work, we present a fast implementation for analytical image reconstruction from projections, using the so-called "backprojection-slice theorem" (BST). BST has the ability to reproduce reliable image reconstructions in a reasonable amount of time, before taking further decisions. The BST is easy to implement and can be used to take fast decisions about the quality of the measurement,...
