I assume you're referring to my recent post about possibly packaging our
latest beta. Our primary motivation is to get the build tested on a wider
range of platforms than we already have in our CI. We have portability and
correctness as high priorities, and a user base that regularly takes a
released tarball and uses it on some platform that we didn't anticipate
when we released it a few years ago (in an annual cycle). That GROMACS just
builds and runs on whatever your new shiny supercomputer is gave us big
market share in Japan (because we were the only major MD code that could
run on the chips in the K computer), and our never-been-tested-before
performance on the new Cavium ARM nodes that are still just coming out was
mentioned multiple times by others at the recent SuperComputing17
conference. Props to DebiChem for helping us with some of the early
portability testing on ARM and Power!

Hope that helps inform your decision!

Mark
