- I am interested in knowing typical values for communication startup
- costs on various distributed memory machines such as CM-5, nCUBE,
- Intel IPSC, Delta, Paragon, etc. What I mean by communication startup
- cost is the time it takes to begin the actual message transmission
- from the time the user program makes the appropriate function call.
- This should include all the operating system or runtime system overheads
- in initiating the communication in addition to hardware setup time.
- I would appreciate if anyone can point to any papers/reports that
- discuss about these overheads or give the values for any system.
-
- If there is sufficient interest, I will post a summary of replies.

- Thanks,
