METIS fails with non-diagonal Identity matrix

[Dinesh_S_]

Numerical factorization stage seems to break with multi processors run for sparse Identity matrices for METIS or parallel METIS

HI Danish,

Can you put these lines in your code and rerun example with last MKL that you have?

char buf[buf_len];

MKLVersion ver;

printf("\nIntel(R) MKLrelease version:\n");

MKL_Get_Version_String(buf, buf_len);

printf("%s\n", buf);

MKL_Get_Version(&ver);

printf("    Major version:          %d\n", ver.MajorVersion);

printf("    Minor version:          %d\n", ver.MinorVersion);

printf("    Update version:         %d\n", ver.UpdateVersion);

printf("    Product status:         %s\n", ver.ProductStatus);

printf("    Build:                  %s\n", ver.Build);

printf("    Platform:               %s\n", ver.Platform);

printf("    Processor optimization: %s\n", ver.Processor);

I see the issue on  windows MKL2017.2 and MKL2017.3, but it passed correctly on MKL2017.4

ok I will do that. I recall that I have tried 2018 Update1 but faced with same issue

Dinesh, please check if the problem you reported still exists with the latest MKL 2019 u3.
