VTune hotspot analysis: LAY16_Loop_M16gas_1?

Jump to solution
Hello,

I get the following results using the latest VTune and MKL on Linux:

Top Hotspots
Function CPU Time
LAY16_Loop_M16gas_1 1.182s
mkl_blas_dgemm_pst 1.079s
LAX16_N4_Loop_M16gas_1 0.706s
tmatrix::delete_column_with_gap 0.583s
mkl_trans_mkl_domatcopy2_n 0.359s
[Others] 4.426s

I would like to tackle them but I have no idea what these LAY16_Loop_M16gas_1 or LAX16_N4_Loop_M16gas_1 are, or more importantly where they are originating from ...

Can anyone advice?

Thanks in advance,
Best regards,
Giovanni

Hello,

These are some internally function calls in the MKL. They look fine to be there.

Thanks,
