Pilot GPU nodes on Biowulf cluster (Biowulf)Date: 30 November 2010 09:11:30
From: Susan Chacko (susanc@HELIX.NIH.GOV)
Graphics processing units (GPUs) are specialized microprocessors originally designed for video and rendering. More recently, compute-intensive programs in the life sciences have been ported to GPUs to explore potential performance benefits of their massive compute power. A pilot GPU cluster has been installed to investigate the performance of GPUs for the types of computations that are performed here at NIH. The Biowulf GPU nodes contain: * 2 x Nvidia M2050 (Tesla Fermi), each: 2.8 GB memory, 448 cores * 2 x Intel Xeon X5650 (2.67 GHz), each: 12 cores * 48 GB DDR3 memory * 450 GB disk (7200 rpm SATA) * Each node is connected to two networks: QDR Infiniband (32 Gb/s) and 1 Gb/s ethernet. The GPU nodes are integrated with the Biowulf cluster and can be accessed via 'qsub' as usual. We have installed and tested the CUDA versions of NAMD, Amber and several bioinformatics programs on these nodes. Details about submitting jobs to these nodes and the results of our benchmarks are available at http://biowulf.nih.gov/gpu.html Users are invited to investigate these GPU nodes for their jobs. Please let us know of any benchmarks you run, and of any other GPU-enabled programs that you would like installed. Biowulf/Helix staff.
