I found that zhetri seems not to be threaded in MKL 11.0.
In my program, zhetri uses only one thread, but zgetri uses four threads.
Does anyone know detail about this problem.
Platform: Core i7 2600K
MKL: MKL 11.0 update 1
link option: icc -mkl=parallel
Sorry, I corrected my mistakes in this post. (hetrf -> hetri)
zhetri is not threaded, but you can use the zhetri2 which uses a faster algorithm an also benefits from level 3 BLAS and threading is avaialable in that.
