AVX version #1

Hi, I'm pretty interested in testing your CSR5 format, but unfortunately do not have an AVX2 cpu. Do you possibly have an AVX version of csr5_spmv_avx2.h, which you could send me?

Best regards, Andreas

Hi Andreas,

Our current implementation of the CSR5-based SpMV uses some vectorized bit (integer) operations not naturally supported by AVX intrinsics. But it's definitely worth a try to develop an AVX version using FP intrinsics for going around. I'll post any new findings here.

Best,

Weifeng
