Dear Devs, is the PCBJACOBI solver fully ported to GPU in the latest petsc-dev version? if not, is there any intention to do so in the near future?
I have a convection-dominated (with strong discontinuities in the flow field) MHD problem where PCASM and PCBJACOBI both work fine with KSPGMRES. Looking for a speedup in my code (which is using a petsc-dev version about two-months old), the only GPU alternative I found was PCJACOBI. This is indeed considerably faster on GPU, but does not converge (neither does, consistently, its CPU counterpart) if not for a few iterations before blowing up. Any other alternative for GPU-based preconditioners or solvers worth trying at the moment?
