HI,

Is the new 19.10 PGI compiler compatible with the new EPYC Rome processors (including instruction set opts) such as the 7702P?

Are there any issues in compiling OpenACC GPU codes on a system with an AMD CPU?

Hi Ron,

We do support Rome, but since we rely on LLVM for the low level instruction selection, our support level depends on what LLVM support. PGI 19.10 ships with LLVM 8.0 with 9.0 expected to be added next year.

No, we have not seen any issues with compiling OpenACC GPU codes on AMD CPUs, and we do have AMD+NVIDIA GPU systems here that we use for testing.
