Computer Cluster Ordered
Last week, I got word that the 16-core processors were available for order from our supplier. I placed an order for our dedicated cluster that will be composed of
- 8 nodes each with 64 cores and 256GB of RAM
- A total of 512 cores and 2TB of RAM
- QDR Infiniband interconnect
- 48TB of long-term storage space. Scratch space is … Continue Reading ››

Talk: GRBs – Recent developments from Fermi
Peter Mészáros (PSU)
- Are the photons from leptonic or hadronic origin? X-ray to radio: leptonic, MeV: probably leptonic; GeV: debated.
- GRBs are a possible origin for ultra-high energy cosmic rays. For gravitational waves, theoretically but not detected yet.
- GRB 080916c: Adbo+ (2009, Science, 323, 1688): GeV photons "lag" behind MeV photons. Why?
- (Jacob & Piran 2008): Quantum gravity? Energy-dependent … Continue Reading ››

GPU Meeting (04 Oct 2011)
Lionel London (CRA) – GPU Computing in Matlab
- Matlab Parallel Computing Toolbox (PCT) vs. Jacket
- PCT allows for multi-cpu and GPU computing. Limited to 12 cores on the local machine. Very high level.
- GPU computing with PCT requires an nVidia card with v1.3 compute capabilities. GPGPU with Jacket has relaxed requirements but is very expensive ($4k for 5 … Continue Reading ››
Discussion: Doing Science in the Open
Michael Nielsen
Yesterday I attended a discussion with Michael Nielsen and the GT faculty, where open science was the subject. We covered various venues for promoting collaborative science projects. Some were completely new to me. Let's cover a few examples that were discussed.
