[petsc-dev] Additive Schwarz Method + ILU on GPU platforms

[Angus, Justin Ray via petsc-dev]

Hello,

A project I work on uses GMRES via PETSc. In particular, we have had good 
successes using the Additive Schwarz Method + ILU preconditioner setup using a 
CPU-based code. I found online where it is stated that “Parts of most 
preconditioners run directly on the GPU” 
(https://urldefense.us/v3/__https://petsc.org/release/faq/__;!!G_uCfscf7eWS!bw6qeKcY7MKSvlEgcogdKR7fpjZSOFvka6zfDprUZ_sJHdE-YZmRD6UTqWQW3_uGVBII4P-AG0zaGTLbI67_fQ$
 ). Is ASM + ILU also available for GPU platforms?
