MIC runs on S2 (reading asci files). I had to fix matrix initialization in spmv. I thought I had
done that already. Don't know what happened.
Runs in both binary and asci read mode. Tested on S2 at MSI.
Branch: gordon.
Note: reading an asci file in binary mode will run on the GPU but the results are meaningles.
REading a binary file in ascii mode produces junk and crashes the GPU.
Choose binary versus asciss in spmv.all manually through #ifdef
