Hi, Does Anyone have any information regarding the overhead for Ada rendenezvous in a parallel environment? It would be nice to get a handle on the amount of overhead It take for a rendenezvous. Tony Sterrett sterrett@nosc.mil

I would suggest getting in touch with your vendor and asking for any benchmarks related to tasking, specifically: PIWG C/T tests (PIWG :== Performance Issues Working Group) Hartstone test (from SEI, real-time applicability) Rendezvous are much lighter weight than full-blown processes (kind of a fore-runner of the current fashionable 'lightweight threads' POSIX and Unix-ish mechanisms). Don't be too surprised if you start seeing rendezvous implemented on top of OS-supported lightweight threads, especially in multi-processor Unix environments. .Bob. -- Bob Kitzberger Internet : rlk@telesoft.com TeleSoft uucp : ...!ucsd.ucsd.edu!telesoft!rlk 5959 Cornerstone Court West, San Diego, CA 92121-9891 (619) 457-2700 x163 -- =========================== MODERATOR ============================== Steve Stevenson {steve,fpst}@hubcap.clemson.edu Department of Computer Science, comp.parallel Clemson University, Clemson, SC 29634-1906 (803)656-5880.mabell
