Hi Ashwin,
I put together a branch with our GPU bug fixes:
https://github.com/Tech-XCorp/petsc/
There is only one branch in this repo: gpu-master. Be aware that this
branch is even
Thanks Dominic! I'll give you some feedback soon!

Hi Karli,
PR #178 gets you most of the way. src/ksp/ksp/examples/tests/ex32.c uses
DMDA's which require a few additional fixes. I haven't opened a pull
request for these yet but I will do that before Thursday.
Regarding the rebase, wouldn't it be preferable to just resolve the
conflicts in

Hi,
I am new to PETSc and trying to determine if GPU speedup is possible
with the 3D Poisson solvers. I configured 2 copies of 'petsc-master' on
a standalone machine, one with CUDA toolkit 5.0 and one without (both
without MPI):
Machine: HP Z820 Workstation, Redhat Enterprise Linux 5.0

Hi Dominic,
I've got some time available at the end of this week for a merge to

Best regards,
Karli
