Hi Rick, Mark Gebhart, another grad student at UT, has been working on PARSEC v2.1 as a follow-on to what he and I were able to complete last fall. We are just about finished with modifications to the build scripts included in the package, and we can forward everything along when we polish it up. At this point, I think we have all benchmarks compiled, and 10-11 of the 13 working. More updates soon, Joel
