Re: [petsc-dev] Should we add something about GPU support to the user manual?

Hi Gautam,

Apologies for overlooking this. The slides are now available online:

  https://www.mcs.anl.gov/petsc/meetings/2019/slides/mills-petsc-2019.pdf

There isn't a whole lot in terms of GPU results in there, but GPU support is 
currently a very active area of development for the PETSc team and we should 
have a lot more to report soon. (We'll have several presentations at SIAM-PP in 
Seattle on this topic, for instance.)

Best regards,
Richard

Hi Richard,

Information about PETSc’s support for GPU would be super helpful. Btw, I 
noticed that in PETSc User 2019 
meeting you gave a talk 
on "Progress with PETSc on Manycore and GPU-based Systems on the Path to 
Exascale”, but the slides for the talk were not up on the website. Is it 
possible for you to share those slides or post them on the online?

Thanks,
-Gautam

Fellow PETSc developers,

I've had a few people recently ask me something along the lines of "Where do I 
look in the user manual for information about how to use GPUs with PETSc?", and 
then I have to give them the slightly embarrassing answer that there is nothing 
in there. Since we officially added GPU support a few releases ago, it might be 
appropriate to put something in the manual (even though our GPU support is 
still a moving target). I think I can draft something based on the existing 
tutorial material that Karl and I have been presenting. Do others think this 
would be worthwhile, or is our GPU support still too immature to belong in the 
manual? And are there any thoughts on where this belongs in the manual?

Agreed. That way we can make it very clear that this is WIP, interfaces
will change, etc.
