This adds a couple of changes to this project

  • Enables CUDA in the project, under the __CUDACC__ define
  • Adds a CUDA-aware MPI distribution scheme
  • Adds GALATIC to the includes, allowing access to its methods
  • Combines all of these to add the method Mult_AnXBn_DoubleBuff_CUDA

Initial results are below:
delaunay matrix runtime (s), 183M (n=100)
rmat matrix runtime (s), 8M (n=100)

Add first optimizations
f92d58b 
- Begin to add optimizations (remove excessive copies, reverse multiplication order, etc.)
- Add some debug statements to find seg fault, to be removed later
- Need to offload some kernels (tupling, merging, decompressing) to GPU, and expand to CSC
