Solaris 10 u5 (due soon) begins to offer support for shared contexts. My understanding is that this is the type of problem it is aimed at. If you are running a recent release of something that claims to be SunOS 5.11, you would already have this. If you already have the shared context enhancement, then either I am wrong about what it is supposed to do, or the shared context code is not being triggered by your code. -- Mike Gerdts http://mgerdts.blogspot.com/ _______________________________________________ perf-discuss mailing list perf-discuss@opensolaris.org
