PETSc algebraic solvers now run on GPU systems from NVIDIA and AMD. This sometimes provides an alternative high-performance, low-cost solution technique.

We recommend working with petsc master (git branch) if you wish to work witht his feature.

If you use the PETSc GPU code in your published work, please cite the following paper:

WARNING: Using GPUs effectively is difficult! You must be dedicated and willing to get into the guts of GPU usage if you are serious about using GPUs.
