Thanks Karl, Matt,
I thought I created all vectors of CUSP type. I'll double check.
I was trying to find vectors that I may have accidentally setup not with
CUSP type through somehow interface with the SNES solver?
I'll also double check w/ the cuda examples as Karl suggested.
There are 6 Tesla M
Please read the large boxed message about debugging mode.

Hi David,
the cuda-runtime might spawn threads in addition to PETSc. How many GPUs
do you have on your system?
You might also want to compare with the CUDA examples. If they also run
at ~800% CPU utilization, then it's definitely due to the CUDA runtime.
Note that there might full CPU utilizat
Thanks Jed.
I was trying to run it in dbg mode to verify if all significant parts of
the solver were running on the GPU and not on the CPU by mistake.
I cant pinpoint what part of the solver is running on the CPU. When I run
top while running the solver there seems to be ~800% CPU utilization
that
thanks Matt,

Hi,
I'm using petsc 3.3p4
I'm trying to run a nonlinear SNES solver on GPU with gmres and jacobi PC
using VECSEQCUSP and MATSEQAIJCUSP datatypes for the rhs and jacobian
matrix respectively.
When running top I still see significant CPU utilization (800-900 %CPU)
during the solve ? possibly from so
