[petsc-users] Petsc Binary Write - Memory

[venkatesh g]

Hi

I am trying to write very large sparse matrices A and B for solving
generalized Eigenvalue problem

so that I can use SLEPC ex7.c code.

I want to read matrices from file according to that code. And I generate
these matrices from Matlab using PetscBinaryWrite.m

However, it exceeds my 256 GB RAM in one of the machines. So I am unable to
generate these binary matrices.

Kindly let me know how to write them efficiently.

cheers,

Venkatesh
