PARDISO_64 compiler assisted offload

[Ivan_K_6]

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.

Thank you, Gennady.

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!

[Ying_H_Intel]

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

Ivan, the problem is reproduced on our side. Affected the latest 11.3 version too. We will keep you updated when the problem would be fixed.

Ivan, please check if the issue exists on your side with the latest update - MKL 11.3 update 1 and let us know the results.

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.
