In this video from the recent Argonne Training Program on Extreme-Scale Computing, Bill Gropp from the University of Illinois Urbana-Champaign presents: MPI and Hybrid Programming Models. “Blue Waters ...

While many application tuning guides focus on understanding the performance of an application on a single node, a very scalable application will use multiple node to achieve very high performance.

I haven't found any terribly good web tutorials on learning MPI. I have several ideas of things I can enhance by porting them to MPI (evolutionary code, can be massivly parallel), but I haven't found ...

Research Computing at the University of Colorado Boulder is one of 17 satellite sites across the country for the XSEDE HPC Monthly Workshop on April 18 and 19. This month’s two-day workshop focuses on ...

I've been covering various scientific programs the past few months, but sometimes it's hard to find a package that does what you need. In those cases, you need to go ahead and write your own code.

We describe a program for the parallel implementation of multiple runs of XSTAR, a photoionization code that is used to predict the physical properties of an ionized gas from its emission and/or ...
