Crash while calling pdmr2d for a large matrix

Hi,

I recently parallelized my fortran90 code using Intel MKL ScaLAPACK.

With relatively smaller matrices it worked fine,

however when I ran my code for a double-precision real matrix of size 40656 by 40656, it crashed.

The error messages are as follows:

MKL_SCALAPACK_ALLOCATE in mr2d_malloc.c is unsuccessful, size = 13223282688

I have tried to resolve this problem or to find a workaround for a week, but I couldn't.

Any help or comments would be greatly appreciated.
