Hi Antoine,<br>
<br>
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. <br>
<br>
Karl, do you have any comment on this?<br>
<br>
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.<br>
<br>
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?<br>
<br>
