I'm trying to locate the system call "mmap()", or a Cray equivalent
under Unicos. Does such a beast exist ?

Also, does anybody have sample code that they are willing to share,
for high speed (network/disk) io under Unicos, using large data sets ?
I'm primarily interested in the kind of tuning one can do to maximize
the transfer rate.

Will summarize responses, if this is of general interest.


Vinod.
