Intel MKL BLACS fatal error

$

Hello,

My program ends prematurely with the following message:

Intel MKL BLACS fatal error: cannot allocate memory, aborted. srun: error: n2176: task 0: Exited with exit code 255

The function call that seem to fail is:

blacs_gridinit(icontext,'r',nprows,npcols)

The first call goes well but the second doesn't (Newton's algorithm), even though function

blacs_exit(1)

is used to exit BLACS. Any idea where it comes from?
