Elemental is available via PETSc (http://mcs.anl.gov/petsc), which is part of ACTS. We might be able to talk ACTS into giving Jack a session at the tutorial session next year. (Disclaimer: I'm a PETSc developer and helped with the Elemental interface.)

Honestly, I doubt it. Getting added to such a list has both political and merit-based components.

Interesting. I had the impression it was just meant to be a repository for DOE-related numerical tools.

That's a shame, because having collections of useful tools like that makes it a lot easier to keep track of options.

Given that a few dozen US-based students attend ACTS every year, I hardly see how it is a game-changer w.r.t. the widespread acceptance of Elemental. I think the internet is doing just fine so far.
