HPC Virtualization Fun

Douglas Eadline looks at Virtualization in the HPC space:
“To see how virtualization might play in HPC, let’s consider how programs operate on a cluster. A parallel MPI program is basically a collection of individual programs (processes) running on the same or different node. Messages are essentially a way to copy memory from one program to another. Programs are “placed” on specific idle nodes/cores by a scheduling program (such as PBS, Sun Grid Engine, or Torque). The programs are managed by the all-knowing scheduler and once placed on a node, stay there until complete. Communication takes place over an interconnect, but as far as the scheduler is concerned, what you do with your nodes is your business. This model has worked well for HPC clustering although it is not the only one. Full Story

About Rich
FlexRex began his life as a cartoon character I created a Sun Microsystems. As the world's first "fictional blogger," he appeared in numerous parody films that made fun of the whole work-from-home thing.
