We really missed the boat by not rebranding as PETAi ("intelligence is
the easy part") and registering pet.ai.

Re: [petsc-dev] OpenMP for GPU course
These are well-organized events that puts application teams together with compiler developers and the like. I served as a mentor for the Boulder hackathon last year (joining a NASA team that included PETSc user Gaetan Kenway) and learned a lot. It's highly recommended to prepare for the event by focusing the code you want to work on to something concrete and easily modifiable, and to have a test suite that can be easily run to evaluate correctness and performance. In our case, Michael Barad had done an exemplary job in that preparation.
