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?
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.
