Hello, I'm using cuda enabled hypre and it works fine when i configure petsc to download hypre and set --CUDAFLAGS='-default-stream legacy'. But when I set --CUDAFLAGS="-default-stream per-thread" I get high residuals with the gmres solve on hypre. Is this option compatible with hypre? Am I missing a synchronization point? Please let me know your input.
