How to compile

Configure using config.mk. Make sure the TAG is set to the proper compiler configuration file. For example TAG = GCCa64fx to include the file 'include_GCCa64fx.mk'.
For using LIKWID (optional): LIKWID library has to be installed (https://github.com/RRZE-HPC/likwid), ENABLE_LIKWID has to bet to true in config.mk. Proper paths has to be set in include_LIKWID.mk
After configuration run make to compile

How to run

Get options using ./spmv-[TAG] -h
For running with HPCG matrix of size 128^3 on 1 CMG using SELL-32-1, currently only C=1 (CRS) and C=32 code is optimised:

OMP_NUM_THREADS=$thread OMP_PLACES=cores OMP_PROC_BIND=close ./spmv-[TAG] -S 128 -C 32 -Z 1
