Your EC2 is probably on a Xeon, yes? My Z620 is a Xeon.

type "git log" in the cado-nfs directory to find out what commit version you're running:

I don't remember how to "get" an earlier commit, but I'm sure it's in the docs. I know I had to do that in the past, but my memory is only good for a short period of time.

I will have to run up a Colab session and check these numbers also.
