I am using Intel MKL version 11.2 update 3 (latest I believe) on Mac OS X Yosemite (10.10.3). Specifically I am noticing that the PARDISO direct sparse solver is crashing in the 64 bit mode (compiled with -DMKL_ILP64 -m64). It runs fine in the 32 bit mode. My matrix size is 10000 with about 1 million non-zeros. Are there any known issues with the above system configurations ? Any help is appreciated.
