Segfaults

[skinnerr]

I've been working with block-cyclic ordering, and I think I have it implemented correctly now. Everything compiles fine, but when I run the program (in serial, and regardless of block size) I encounter a segmentation fault in main(), some time after all the initial print statements. I'm pretty sure it happens during the actual benchmarking. Any ideas on how to determine the cause of the problem?

Valgrind is excellent. You can also run in a debugger, in which case it will trap on invalid memory access. Remember to compile with debugging symbols (-g).
