Hello,

I am interesting in using PETSc for iterative solving sparse linear system on multi-GPU systems.

RedHat 5.5, Cuda 3.2

Question1: Is it my problem or a bug of the algorithm?

Don't know why that happens.

Question2: Where can I find simple doc or example, which describe how to solve sparse linear systems on multi-GPU systems using PETSc?

Many of the examples will run in parallel with GPU for example: src/snes/examples/tutorials ex19 -pc_type jacobi -da_vec_type cusp -da_mat_type aijcusp Barry
