threading for mkl_?bsrmv routines?

Ron_Green — Wed, 22 Jul 2015 22:21:24 GMT

Linux, MKL 11.x

Are the mkl_?bsrmv routines threaded?

We're seeing threading if we use mkl_?csrmv routines. But when using mkl_?bsmrv routines we do not see threading.

Link line is -L$(MKLROOT)/lib/intel64 -lmkl_rt -lpthread -lm

Are the mkl_?bsrmv routines not threaded?

Thanks

Ron

mkl_bsrmv is not parallel. On

Response from MKL engineers:

mkl_bsrmv is not parallel. On the contrary, mkl_bsrgemv is implemented in parallel and has similar functionality.

What I can recommend to customer – use our inspector-executor API of SparseBlas that have been already published in MKL 11.3. We support BSR mv functionality in this API and it is implemented in parallel.
