[petsc-users] Problem with BLASdot in 3.19.4

Tue Sep 19 01:04:16 CDT 2023

Hi Barry,

Visual Studio 2022 is the problem! The code linked to Petsc 3.18.6 built
with VS 2022 also crashes at the same place. The same errors are shown
below. I don't remember for sure, but I don't think I was able to configure
Petsc 3.19.4 with VS 2019. However, I will still try that next.

Thanks for your help,

Thuc

Thanks a lot Barry, for getting back to me. Will do what you have suggested,
and get back with the results.

Best regards,

Thuc

  Ok, two things are being changed at the same time: the version  of PETSc
and the version of Visual Studio. 

  Could you please try with the new Visual Studio version but the same older
PETSc version? If that works could you try with the old Visual Studio
version but the new PETSc version?

Dear Petsc users and experts,

If someone can direct me how to track this bug, I would really appreciate
it.

The Petsc DLL library version 3.19.4 was built on Windows 10 with Visual
Studio 2022, and with Microsoft MPI 10.1.2 and Intel MKL 2020.3.279. The
same code works fine with Petsc 3.18.6 using the same versions of MS MPI and
Intel MKL, and built with Visual Studio 2019.

When my code calls PetscCall(KSPSolve(...)), it gets to
PetscCall(KSPGMRESCycle(...)), PetscCall(VecNormalize(VEC_VV(0), &res)),
PetscCall(VecNorm(x, NORM_2, &norm)) and then crashes in VecNorm_Seq() at:

                PetscCallBLAS("BLASdot", ztmp[type == NORM_1_AND_2] =
PetscSqrtReal(PetscRealPart(BLASdot_(&bn, xx, &one, xx, &one))));

I tried to step into BLASdot_, but was unable to. I assume BLASdot_ belong
to Intel MKL, and its library does not contain debug information. After the
code exits, the errors are shown below the hash line.

Should I install the latest Intel MKL to work with Petsc 3.19.4?

Many thanks in advance for your help,
