Updates:
   (Jan 2017, avx512 and opencl): added two versions: AVX-512 for Knights Landing Phi (KNL) and OpenCL for nVidia GPUs.
   (Jul 2016, phi): fixed the same two issues in the original AVX2 version. Thanks Jan Philipp Ecker!
   (Jul 2016, avx2): Improved performance of y-vector update. Thanks Jan Philipp Ecker!
   (Jul 2016, avx2): Fixed a bug in processing small matrices. Thanks Jan Philipp Ecker!
   (Apr 2016, cuda): Fixed a bug in timing. Thanks Shigang Li!


CPU (AVX2) version

  1. Set environments for the Intel C/C++ Compilers. For example, use source /opt/intel/composer_xe_2015.1.133/bin/compilervars.sh intel64,
  2. Run make,
  3. Run ./spmv example.mtx.
  1. Intel Core i7-4770R CPU with Ubuntu 14.04 64-bit Linux installed.
  2. Intel Xeon E5-2667 v3 dual-socket CPUs with Redhat 6.5 64-bit Linux installed.
  1. Currently, only 64-bit double precision SpMV is supported.
