"vi" & Supercomputer Performance

[Mike Muuss]

Dan -

The problem with using NFS is that, in the scenario under discussion,
the Cray would be required to NFS transfer the *entire* file to the
editor running on the workstation, and then receive the *entire* file
back to the Cray again using NFS.

For changing a few lines in a medium-sized source file, this is STILL
more expensive of Cray time than running the editor locally on the Cray.

For highly modularized source code, where the source files are only
a few dozen Kbytes, using NFS in this way is certainly a performance "win".
But running a GREP through your sources via NFS is likely to be a big
loose.

Face it, folks:  using the Cray interactively in the edit-compile-test
cycle is a good, efficient use of time.  Both Cray time and user time.
	Best,
