I meant no-mpi, libMPI, tMPI.

Sure but then you are already missing many possible configurations.
I'm wondering whether it would make sense to pick randomly
configurations from the all-vs-all configuration matrix. The most
important configurations would already be tested by the Gerrit
auto-trigger and with the random selection all odd combinations have a
change to get picked over time.

No the build time is currently much higher on all VMs. The IO
performance is a significant factor.

It should be easy to setup. I'm happy to help anyone who wants to add
more Jenkins jobs.
