CUDA is cool if you know how to use it.

Re: HW 11 Results

Problem 4, with NP=128

Max array size handled: 260,000,000
GPU Execution Time: 534.310 ms
Handcrafted MPI Execution Time: 5462.871 ms
MPI_Reduce Execution Time: 5206.865 ms

It's interesting that my results are so different from Chetan's. I'll have to try NP=5.
