thanks! I seem to be getting the same answer on cpu and gpu in 3d w/ double.
However, increasing the dof with -refinement_limit 0.01, the residual is
differing slightly (see below).
in single precision, do you have an idea of the upper bound limit on
degrees of freedom
such that the sieve gpu FEM

Ah well, I was getting around to fixing this. The problem is a little
deeper. The C versio
I'm pretty sure I pulled the latest on this petsc-dev and Generator, but

I have some existing libMesh code that I would like to use with this ex52
GPU code example.
I think it may be reasonable to use the existing code for setup of initial
conditions and jacobian calc,
But then use the GPU residual calculation.

I had trouble compiling in single precision using the some of the external
package options I was using for double.

Excellent. Now, my thinking was that GPUs are most useful doing single
work, but
I can see the utility of double accuracy for a residual.
My inclination is to define another type, say GPUReal, and use it for all
kernels.

thanks! its running, but I seem to be getting different answer for cpu/gpu ?
i had some floating point problems on this Tesla M2070 gpu before, but
adding the '-arch=sm_20' option seemed to fix it last time.
is the assembly in single precision ? my 'const PetscReal jacobianInverse'

should this possibly be PetscScalar ?

Andy Terrel already busted me about this today. I pushed a new tarball to
the ftp site, so this will work
thanks! when generating the header file ex52.h

Hi,
I had a question about the status of example 52.

Can this example be used with a DM obj
