Executor factory not found

[reikdas]

I tried performing SpMM over the following matrix market files:
https://sparse.tamu.edu/HB/662_bus
https://sparse.tamu.edu/HB/bcspwr06
https://sparse.tamu.edu/TAMU_SmartGridCenter/ACTIVSg2000

The command I used to execute SpMM was - python3 run_matrix.py -m 662_bus.mtx -t 1 -b 512 -o temp.csv

But I got an error that looks like:

Error: Executor factory not found: c22a5_AVX512_512_4x4 for kernel desc: sop::KernelDesc<float, sop::CSRStorageTypes<float*, int>, sop::PackingDesc<(sop::PackingStrategy)2, (sop::PackingStrategy)2>, (sop::UPanelReorderingStrategy)1>
   /home/reikdas/spreg2/spmm_nano_kernels/include/MatMulSpecialized.h:166

Would anyone be able to point me to what might be happening here?

Hi @reikdas sincerest apologies about the delay, can you please provide the full output of the script? Unfortunately im not able to reproduce this on my end I get:

Sp. Reg.  : 83.44 us  correct

in the output you should see the filename for a yaml file created in the tmp directory (e.g. above I get /tmp/sp_reg_tiling_dlmc_test/AVX512/yamls/no_filelist_AVX512_5e125.yaml ), could you please share the contents of this file too please?

You must have solved the problem already, but for anyone who's facing this issue, you might have not turned on AVX512 when configuring with CMake.
