Perhaps --with-64-bit-indices=1 would help this use case? if using latest petsc version - the following build might work: --with-cc=win32fe_cl --with-cxx=win32fe_cl --with-64-bit-indices=1 --download-metis --download-parmetis .... Satish On Fri, 27 Dec 2024, Matthew Knepley wrote:

Dear Developer:

I am a PETSc user and I have the following error when calculating 1 million grids using PETSc in my windows computer. It came up after calculating it for a while,

This is an out-of-memory error. Perhaps you are holding onto memory? You can run a small run using -malloc_debug and it will show unfreed memory at the end.

Thanks,

Matt
