Registration for OSG All-Hands Meeting is Open!

Report from CHEP 2015

japan-2015The 21st International Conference in High Energy and Nuclear Physics (CHEP) took place from April 13 to 17 in Okinawa, Japan and had 450 participants from 28 countries. The conference, held approximately every eighteen months, overviews trends in computing technology and practices as applied to high energy and nuclear physics.

This year’s CHEP conference was held just months before Run 2 of the Large Hadron Collider (LHC) is scheduled to commence. This run is expected to produce a larger volume of data and the need for more computing resources than ever before at a physics experiment. To help prepare for the needs of the LHC experiments, an emphasis of the presentations was how to leverage technologies and resources not traditionally used in HEP.

These technologies and resources include High-performance computing (HPC), cloud computing, and virtualization. The latest advancements of technologies that are more commonly used in HEP, and which underpin much of the Open Science Grid, were also presented. In particular, there were parallel session presentations on HTCondor-CE, the OSG Open Facility and glideinWMS. Additionally, a plenary talk given by Oliver Gutsche of Fermilab presented Diversity  Computing Technologies and Strategies for Dynamic Resource Allocation which gave an overview of computing technologies and platforms, including the OSG, used in HEP.

These and many other topics were covered in the over 500 oral and poster presentations, ending with an announcement of the next CHEP, in Fall 2016, in the San Francisco Bay Area.
