[petsc-users] loading huge matrix with MatLoad in parallel implementation

[Yujie]

Dear PETSc developers,

When the program based on PETSc runs in parallel mode, how much size
of the matrix can MatLoad load?
Does the program need to save the whole matrix in one CPU, or is each
CPU in charge of the part of the matrix?

For example, I have one matrix of ~30G. There are two CPUs on each
nodes with totally16G memory. I have 8 nodes. I use 16CPUs for
running. Can I load this matrix using MatLoad? Thanks a lot.

Regards,
Yujie
