mkl_sparse_spmm: Internal memory allocation failed.

Sid — Fri, 09 Mar 2018 22:45:21 GMT

Hi There,

I'm trying to debug why mkl_sparse_spmm returns with SPARSE_STATUS_NOT_INITIALIZED status and a system with plenty of free memory. Would appreciate help on this.

Thanks,

Hello,

Can you please provide more details about the way you use mkl_sparse_spmm and the MKL version?
I'd also appreciate if you attach a small reproducer so that I'll be able to investigate this case thoroughly.

Best regards,
Maria

Please take a look at the

Please take a look at the example - mklroot\examples\spblasc\source\ sparse_spmm.c Everything works as expected with 2018 u1.

Thanks, I'm going to upgrade

Thanks, I'm going to upgrade to 2018u1 and give it another try.

Here is an example that fails

Here is an example that fails with allocation failure: https://gist.github.com/sgolestane/a24265a0d0c04db3d31ec2c4b6e6b672 It may be coincident that the result of the calculation is an all zero matrix.

Hello Sid,

Thank you for pointing out the issue with zero resulting matrix.
Also initially you were speaking about returned status SPARSE_STATUS_NOT_INITIALIZED, does this problem still exist?

Best regards,
Maria

Hi Maria,

Hi Maria,

Yes. mkl_sparse_spmm returns with status SPARSE_STATUS_NOT_INITIALIZED when the result matrix is zero.

I checked with MKL 2018 u2

Gennady_F_Intel — Sat, 07 Apr 2018 02:51:19 GMT

I checked with MKL 2018 u2 and don't see this problem.

Hi Gennady,

I just installed MKL 2018 u2 for macos (m_mkl_2018.2.164.dmg) and still getting status 2:
