[petsc-dev] PETSc port to OpenCL

[Paul Mullowney]

Hi Antoine,

I don't think one can claim that PETSc supports OpenCL right now. 
However, I think progress has definitely been made in getting core 
vector computations (for a Krylov algorithm) to run via OpenCL.

Karl, do you have any comment on this?

Once those are in place, it wouldn't be too difficult to get a prototype 
matrix class into PETSc where the other core pieces of a solve, mainly 
SpMV (and potentially the triangular solves) run on AMD devices.

The real question is, what algorithms does your customer want to run? 
i.e. is it a KSP solve? What is the preconditioner? How big is the 
system? Are multiple GPUs neeeded?
