Use the version of mpich built into the ecpe4s/ubuntu20.04:23.05 image instead of building a new one. This replaces an mpich that used ch3/tcp with one that uses ch4/ofi.

@scottwittenburg this looks great, I will give a better review in the coming days |

@scottwittenburg does this improved the perf of mpich tests? Maybe we have to run the CI a few times to check this. Note that previously ADIOS2+MPICH+ch4/ofi was very flaky, maybe is not the case anymore with a newer MPICH version. |
No, this didn't help at all, and since it took about an hour (like the previous mpich tests), I'm not sure running more times will help. I may close it, or else use this PR as a way to test other approaches. |
|
@scottwittenburg I guess that this was superseded by #3883, shall we close? |
|
Yes, thanks. |
