Hello, all.
I am trying to offload a call to `pardiso_64` to a mic via compiler assisted offload.
`pardiso_64` returns error code `-12` if it is linked against 32 bit libraries. I am following the instructions from the link line advisor, but still getting `-12`. Please see the attached makefile.
MKL version 11.2.3 (`composer_xe_2015.3.187`)
Thanks.

Hello Ivan,
The behavious should be by design.
The manual add the notes:
NOTE
pardiso_64is supported only in the 64-bit libraries. If pardiso_64is called from the 32-bit libraries,
it returns error=-12.
Best Regards,
Ying

Hello, Ying.
Are you implying that offloading to the MIC (xeon phi) inly supports 32 bit architectures?
Thanks!

sorry. I'm misunderstand your question. you worked 64bit with pardiso_64 , right? Please ignore the message I mentioned about the 32bit library.
Regards,
Ying

Philipp, the problem was exactly regard to Pardiso_64 API but not Pardiso. That's why you didn't see the problem.
Yes, that's true - pardiso and pardiso_64 have no differences for compiler assisted offload to MIC when using ILP64 interfaces as well.
