[petsc-dev] PETSc port to OpenCL

[Karl Rupp]

Hi all,

actually, I forwarded Antoine to this mailinglist. I'm currently working 
on getting ViennaCL into PETSc *before* the release, so for Antoine's 
purposes we should soon be ready.

As Paul put it, it is important to get more context on what your 
customer wants to run. Is your customer using PETSc already?

Best regards,
Karli
