[petsc-users] MatView for huge matrix output

[Yujie]

Dear PETSc developers,

I want to output an about 36K*36K dense matrix using MatView in binary
format. I use RedHat Enterprise 5 64bits system. However, when the
file size of output matrix reaches about 2.7G, the codes pause and
don't response for a long time (almost 3 hours). Could you help me
figure out what happened? Thanks a lot.

Regards,
Yujie
