High-Availability Storage With GlusterFS 3.0.x On Debian Squeeze - Automatic File Replication (Mirror) Across Two Storage Servers This tutorial shows how to set up a high-availability storage with two storage servers (Debian Squeeze) that use GlusterFS. Each storage server will be a mirror of the other storage server, and files...

Vincent Hindriksen from StreamComputing writes that it can be difficult to determine if your CPU supports OpenCL, so he put all the information in one handy place. Often it is not clear how OpenCL works on CPUs. If you have a 8 core processor with double threading, then it mostly is...

In an effort to measure the size of the universe, researchers are using the Jaguar supercomputer at ORNL to simulate the explosions of white dwarf star supernova. The physics of supernova explosions is something astrophysicists have been trying to figure out for about 50 years now,” said Stan Woosley, principal investigator of an Innovative and Novel Computational Impact on Theory and Experiment (INCITE) project and professor of astrophysics at the University of California–Santa Cruz. “It is an...

  Our GTC 2012 coverage continues as Dan Olds examines the growth of the CUDA environment from 150,000 downloads in 2007 to 1.5 million today: More importantly, there are 35 NVIDIA-fueled hybrid supercomputers on the Top500 list today. The NDUT Tianhe-1A system, with 14,300 CPUs and 7,100 NVIDIA GPUs, held...
