Regent: ROCm 5.1 retiring from Frontier #1702

Closed syamajala closed 2 days ago

syamajala commented 1 week ago

OLCF is planning on removing ROCm 4.5.2, 5.1.0, and 5.2.0 from Frontier on July 9th. We can either complain or bump the minimum version to 5.4.0.

Regent supports ROCm 5.4.3, so that is fine as far as that goes. However, if I recall correctly, every version newer than 5.1.0 results in the HSA out of resources error we've been tracking with OLCF. Therefore, until we have a fix for that it would probably be best to avoid removing 5.1.0.

We addressed this by moving to ROCm 6.0.0 and LLVM 18. So I don't think we have any remaining reason to object to old versions being removed.
