Basically, is anyone still using it over a self-built system using modules or some similar project? There's some interest in the main Gentoo tree to port to multilib.eclass which I think may be ignoring use cases important to HPC site administrators. In particular, the ability to use emerge and empi to manage multiple mpi/lapack/blas stacks. However, I have no proof aside from positive feedback from back when empi was in development.
I definitely don't want to stand in the way of other motivated developers if everyone using Gentoo for HPC is no longer using empi and instead using systems outside of Gentoo. So, you have a few weeks to speak up. If I don't hear anything back, I'll drop empi and mpi.eclass from the science overlay. -- Justin Bronder
