MKL Stack overflow

Adhiachari__Subraman — Wed, 03 Jun 2020 08:56:30 GMT

Hi,

I am trying to use the MKL library for a sparse matrix solution. I have used a few example cases to input my matrix. My matrix size is 10600.While I define the row and column indexes using the CSR format, however my modified example does not show any error during compilation but while running always fails at "Unhandled exception at 0x0230BF28 (mkl_core.dll) in pardiso_example.exe: 0xC0000005: Access violation writing location 0x0000080A". This happens with any example that I try to modify. Is there a matrix size limit internally set in the MKL lib files?

Any help here is greatly appreciated.

Thanks

Subbu

Subbu,

These sizes have to work without a problem. Could you give us the reproducer to check the problem with the current version of MKL?

Subu, you could try the newest ( v.2020 update 2) version of MKL and give us the reproducer in the case of any further issues.
