pilots to run in ARM machine

[zhangxiaomei]

We were asked to use some ARM resources. Before trying, I would like to ask if it is possible for pilots to run in ARM machines. How much efforts are needed to make it working? Thanks

Python2 pilots won't work, but Python3 pilots should be already working with ARM (at least DIRACOS2 can be installed). Having said that, I don't think we have ever tried, so it would be beneficial if you try and send us results.

Thanks. I will have a try and let you know.

I have a try on ARM with DIRAC7.3. The tests show the python3 pilots are able to run in ARM machine and pull jobs successfully. Only a minor warning with DB12:
"2022-07-07 01:31:37 UTC ExternalLibrary/root WARN: You are executing DB12 using python3, DB12 score is generally higher than it was with python2
2022-07-07 01:31:37 UTC ExternalLibrary/root WARN: Trying to apply a correction...
