Clustermonkey has a post pointing to summer HPC learning programs from the ARC at Georgetown. I’ll copy most of it here without a guilty conscience since it’s educational:
Want to become a cluster ninja and move one step closer to that world domination goal? If you answered, yes, your opportunity awaits this Spring and Summer. One might consider this a shameless plug, but in the interest of world domination (yours not mine) I invite you to take a look at the upcoming raft of advanced cluster short courses. These courses are brought to you by the ARC at Georgetown University (http://www.gridswatch.com). More information can be found at the ARC HPC Training Page.
