The 13th MVAPICH User Group (MUG) Conference is coming up (Aug 18-20 in Columbus). It's a great event for focused technical presentations around MPI and network performance. Great speaker lineup too. Wish I could make it in-person, but virtual attendance is free

This is a huge milestone. We reworked the core to add compiler dependencies, and we're introducing a stable package API.
🚀1.0 also adds concurrent builds, better includes, and much more -- read it all in the release notes!

Sure you can type ⬆️ ⬆️ ⬆️ ⬆️ ⬆️ ⬆️
To get back to that command you need.
But did you also know, you can just type:
! 25
To get the 25th command?
So let me ask you this…
Do you feel lucky punk?
DO YOU FEEL LUCKY???

"All scripts are part of the supplementary materials."
The supplementary materials:
!123
!42
!11
!25
echo "done"
!1
Truth be told, !11 is faster to type and I cannot remember it either. Game on!
