MKL_VERBOSE timestamps

Istvan77 — Mon, 17 Mar 2025 07:22:38 GMT

Hi, currently setting MKL_VERBOSE to 1 or 2

causes the MKL library to print out lines such as

MKL_VERBOSE DGEMM(N,N,....) 3.52us CNR:OFF Dyn:1 FastMM:1 TID:10 NThr:1

This contains the duration of the call, but not its start time.

is there a way to include a timestamps as well which specifies when the called routines execution starts (or ends)?

Thanks

István

MKL_VERBOSE doesn't provide timestamps information. But you could call dsecnd() API in oneMKL to get a relative timestamp. Just need to modify the source code though.

Thanks for the reply. I was hoping though it can provide timestamps as well, as for example cublas logging.
