@suvarchal, this was different from a previous version that was working on Levante. @basava70 replaced this line to have a variable that contains not only cc80 but cuda12.2,cc80 that is then passed to the -gpu flag during compilation. Does this change make sense to you?

I had to comment this particular line for the OpenACC code to work. I am not sure why. If anyone can let me know why, it will be great. But the code is running with this change.

Hi @basava70, thanks for the changes, I have no further comments |
|
Why was this closed? |
|
I was cleanin up branches that I contributed to and that were already merged to main. By accident I cleaned up production_DE in the process. This then closed the PR. |
|
I have restored the branch, but consider rebasing to main, as production_DE has already been merged. Developments merged into production_DE will be lost unless you make a second merge request of production_DE into main. |
This branch has the working OpenACC code. I had to comment out
set(CMAKE_EXE_LINKER_FLAGS) line in src/CMakeLists.txt, among other things. But adding this line seems to break the code. Review it before merging.
Also this code is taking 25 seconds for 1 day. I think this is in accordance what @suvarchal got in LUMI.
