[petsc-dev] GPU and multi-core threaded support in next release?

[Karl Rupp]

Hi all,

I see less problems with OpenCL than with CUDA. Things are getting 
better on the CUDA side, since CUSP and thrust have reached a certain 
level of maturity. Anyway, I agree that it's better (in terms of 
providing good support for GPU-related functionality) to direct people 
to petsc-dev (master) rather than trying to keep maint somehow up-to-date.

Are there any plans to go for shorter release cycles? If (and only if) 
so, the burden on 'maint' is smaller and we could consider GPUs for the 
release.

Best regards,
Karli

That is will we continue with requesting users to use petsc-dev for some (all) of the functionality?  If so, we should turn off the support in the release and print a nice helpful error message when configure is run requested an unsupported mode telling people to use petsc-dev. So we don't get tons of email from people who didn't read the docs carefully.
