[petsc-dev] [GPU] Problem with petsc-dev

[Keita Teranishi]

Barry,

The SNES example program fails at DACreate_2D().  I am not using MPI to build the program (it's Linux white box). Do I need MPI to run the code?

Thanks,

[0]PETSC ERROR: DACreate_2D() line 1338 in src/dm/da/src/da2.c

[0]PETSC ERROR: --------------------- Error Message ------------------------------------

   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.
