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? -Paul > We (AMD FirePro) have a customer using PETSc and trying to port their > thermal/ablation solver code to OpenCL. > > Do you support AMD GPUs and OpenCL? > > Ref: Comparing the AMD FirePro S10000 to the Nvidia Tesla K10, K20 and > K20X > <http://fireuser.com/blog/comparing_the_amd_firepro_s10000_to_the_tesla_k10_k20_and_k20x> > > AMD FirePro^(TM) S10000 Server Graphics > <http://www.amd.com/us/products/workstation/graphics/firepro-remote-graphics/S10000/Pages/S10000.aspx#1> > > Heterogeneous Compute - Tools <http://developer.amd.com/tools/> > > Regards, > > *Antoine Reymond* > > Sr. Strategic Alliances Manager > > AMD Professional Graphics > > O: +(1) 949 336 6244 M: +(1) 949 870 2200 > > 52324A_FireProTechLogo_S_E s Visit us at: Twitter > <https://twitter.com/AMDFirePro>| amd.com > <http://www.fireprographics.com/> > -------------- next part -------------- An HTML attachment was scrubbed...
