Barry, Thanks for the kind response. I am building slepc 3.7.3 and when I configure –with-64-bit-indices=1, I am getting the following error.
./configure --with-64-bit-indices=1 --prefix=/lustre/atlas/proj-shared/csc209/ramki/slepc ERROR: Invalid arguments --with-64-bit-indices=1 Use -h for help When I run ./configure –h, I am getting the following options. Let me know if I am missing something.

It is possible that some integer operations are overflowing since C int can only go up to about 4 billion before overflowing. You can building with a different PETSC_ARCH value using the additional ./configure option for PETSc of --with-64-bit-indices and see if the problem is resolved.

This is a 1D row distributed sparse uniform random matrix with 1e-6 sparsity over 36 processors. It works fine for smaller matrices of sizes with 1.2 million x 1.2 million. Let me know if you are looking for more information. > > -- > Regards, > Ramki > > <slepc.e609742.zip>
