How to delete mkl out-of-core temporary files

Hi,

I'm using pardiso_64 in MKL 11.3.3.1.

When run in out-of-core mode, temporary files are generated. I have set the environment variable MKL_PARDISO_OOC_KEEP_FILE = 1 according to https://software.intel.com/en-us/mkl-developer-reference-c-intel-mkl-par... in order to delete temporary files when computations are complete. (I have also tried = 0 as "keep file  = 1" seemed counter intuitive, but that's besides the point).

I assumed that files would be deleted when I called pardiso_64 with phase=-1 in order to release internal memory. But the files are not deleted.

How can I get pardiso to delete temporary out-of-core files?

Best,
Jens
