[petsc-users] MPI and Matrix Sharing

[Franco Milicchio]

Dear all,

I am currently implementing a FEM software that runs on single hosts, as the DOF number is not big enough to distribute it. However, I need to solve several right hand sides, and to speed the process up, I’d like to share the matrix between processes, so that I could reuse the factorization.

My question is simple: is this a viable approach? 

Thanks,
	Franco
