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,
-Mike
