Theoretical astrophysics represents a major research effort in Australia, with a growing reliance on High Performance Computing to solve some of the most complex problems in astrophysics. The computing landscape is rapidly evolving, with a significant shift underway from classical CPU-based technologies to GPU technologies. The time is ripe for significant investment to take advantage of this new computational paradigm, and in December 2009 the AAL selected a proposal for the
GPU Super-computer for Theoretical Astrophysics Research (gSTAR)
for consideration as part of the $10M Investment Plan for EIF-funded astronomy infrastructure.
gSTAR will be a next generation GPU-based computing cluster for computational astrophysics housed within the Swinburne Center for Astrophysics and Supercomputing. The AAL investment will buy the Australian astronomy community a ~600 Teraflop machine with 200 Terabytes of storage to tackle next-generation computational problems not possible with existing CPU-only architectures.
In preparation for gSTAR, we invite potential users and other interested colleagues to a one day workshop on March 24th at Swinburne University. The workshop will have the joint aims of introducing users to the GPU architecture, informing the community about the relative capabilities, and discussing current and future applications. Approximately 20-30 minutes will be allocated for each oral presentation. There will be no formal proceedings, but contributions will be available on the web after the workshop.
This workshop follows the two day 2010 ANITA Workshop on the 22nd and 23rd (link) and is sponsored by Swinburne University’s Centre for Astrophysics and Supercomputing. Registration is free, and morning and afternoon tea will be provided.
