[petsc-users] slepc NHEP error

[Kannan, Ramakrishnan]

1. I am seeing this error happening in titan as well
2. Export OMP_NUM_THREADS=1, didn’t alleviate and the error still remains the same.
3. I will try petsc-32 bit and check if the error remains the same.
4. I will build my own petsc 64 bit after my trial with 32 bit.

    I don't have access to this machine. You can try setting OMP_NUM_THREADS=1 before launching, not sure if this will make a difference.

    What I was suggesting is to build PETSc locally in your account with --download-fblaslapack --with-64-bit-indices, and build SLEPc against this one.
