Hi Barry,

Thanks for the explanation! Removing the calls to
PetscMalloc(Re)SetCUDAHost solved that issue.

Just to clarify, all PetscMalloc(s) happen on the host and there is no
special PetscMalloc for device memory allocation ? (Say for an operation
sequence PetscMalloc1(N, &ptr), VecCUDAGetArray(cudavec, &ptr) )

Thank You,
