how to invoke ILP64?

[kgore4]

Can anyone tell me how to switch MKL to ILP64 on linux?  I've set MKL_LP64_ILP64=ilp64 in the environment before starting python

I'm getting errors which googling hints at using ILP64 instead of LP64 may solve the issue. The python line is amat=bmat+scalar*(amat-bmat) where the dimensions are 46717 square.

Intel MKL ERROR: Parameter 1 was incorrect on entry to vsSub.

Intel MKL ERROR: Parameter 1 was incorrect on entry to vsLinearFrac.

Intel MKL ERROR: Parameter 1 was incorrect on entry to vsAdd.

Thank you. We have reproduced the issue, and are working towards a resolution. We will update this post to notify you of a fix.

The choice between LP64 and ILP64 is made at the time of compilation, so setting the variable in the environment will not make a difference for Python. 

Thank you,
