We have been trying for some time to write a reliable flush routine for the SCC L2 cache. We often thought we had a solution, but further testing proved us wrong. Michiel's work (his persistence, advice, and contributed code) has finally given us an SCC L2 flush routine. This work is described in http://marcbug.scc-dc.com/bugzilla3/show_bug.cgi?id=195
We have had the latest RCCE in the trunk for quite some time. The only reason we did not make a new release tag was because the emulator was broken. Andreas fixed some key bugs in the emulator that now allow us to tag a release. We now have a RCCE 1.1.0 called http://marcbug.scc-dc.com/svn/repository/tags/RCCE_v1.1.0/. Andreas is also active in the SCC Forum and has helped out a number of SCC users. Thanks, Andreas.
The latest public release of the Barrelfish research operating system from the Systems Group at ETH Zurich now includes support for the SCC. For additional information go to: http://www.barrelfish.org/
