[petsc-dev] Problem with petsc-dev

[Keita Teranishi]

Barry,

I already see a big difference in MatMult routine of ksp/ksp/examples/tutorials/ex2.c, and I am very happy to try that example program.

Thanks,

   You can run, for example, src/snes/examples/tutorials ex19 with the options -pc_type jacobi -dmmg_nlevels 5  -da_vec_type cuda -da_mat_type aijcuda  and run without those last two options to NOT use the GPU and compare the results with -log_summary. We'd be interesting in seeing those numbers also.
