[petsc-dev] Fwd: [ECP-PIs] Updates on the planned Aurora and Frontier exascale systems

[Smith, Barry F.]

  PETSc developers,

    Note that this machine will apparently not support either of our two current GPU backends: CUDA or ViennaCL/OpenCL ;-)

Yes, also recommending OpenACC transition to OpenMP and showing
confidence in HIP over CUDA.

Spec sheet on the current generation of these GPUs.

Are they available in any cloud environments and/or is JLSE planning to get some?

 First news I've seen on Frontier. It is not Nvidia!

 No mention of OpenCL!

Folks - we’ll discuss this more during our next all-PI VTC, but FYI details of the Aurora and Frontier systems are becoming available, which is timely and will help us in honing our exascale plans moving into our CD-2 review this fall.
