[petsc-users] how good is PETSc+GPU's ?

[Gaurish Telang]

I would like to know how well PETSc works with GPU's and the kind of
Speed-ups one can get if one uses PETSc along with GPU's.

Has it been used for scientific studies so far?

[ I think this bit of information (
http://www.mcs.anl.gov/petsc/petsc-as/documentation/faq.html#gpus ) has been
that way for a long time, and hence the above question.

This 2010 article( http://www.mcs.anl.gov/petsc/petsc-2/features/gpus.pdf )
does not mention any comparative studies of the preliminary implementation
of PETSc for use with GPU's with other software libraries. ]

Sincere thanks,

Gaurish
