Hi Richard, Information about PETSc’s support for GPU would be super helpful. Btw, I noticed that in PETSc User 2019 meeting<https://www.mcs.anl.gov/petsc/meetings/2019/index.html> 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?

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? --Richard
