multi-threaded matrix multiplication

Dear Intel MKL developers,

I am integrating the MKL subroutine mkl_zcsrmultcsr in my MPI code. I tested a case with 16 processors, and mkl_zcrsmultcsr is called in every processor in parallel. Once it is called, multi-threaded computing is automatically activated.

The problem I encountered is that 12 processors among all processors work fine while the other 4 processors give memory corruption errors, moreover, these 4 processors can vary during each test. I am not sure what the problem would be. Your advise is well appreciated.

best,

Likun
