Parallel Computing Workshop, Day 5

Today was devoted to hybrid MPI/CUDA programs. The focus was on where in your code you should use each technology, which boils down to using CUDA for processing and MPI for communications. The instructors warned us that CUDA was fairly unforgiving and Southern Man achieved a number of fairly spectacular segmentation faults with his code. In the afternoon we did more benchmarking and learned how to build our own cluster (a topic selected by popular demand a few days ago).
