[SSI-devel] Parallel make on SSI

[Walker, B. J <bru...@hp...>]

Matt,
    Thanks for your interest in the openSSI project and stopping by at
LinuxWorld.   We noticed a couple of things while you playing with the
system - parallel make (make -j18) was not migrating the make program
itself and there wasn't a good way to determine which of your processes
were running on which nodes.

Laura Ramirez, who works on the project, looked into the first issue and
discovered that make -j uses cloning.  As we discussed (I think), we
currently can't split cloned processes between nodes (actually there is
no plan to ever do that).   Without a change to make, the best we are
going to do is to distribute all the things the make spawns (cc's, ar's,
etc.).    Sometime next week we should have an initial look at the
performance impact spreading those processes around the cluster might
have.

As for the "ps" issue, I'll send a note on the ssi-linux-devel list
later today to start a discussion of what we can/should do with ps to
address the issue of knowing where your processes are running.

Note that the "current" release (0.9.9) has problems with NFS.  If
anyone needs a fixed release, Brian has a 0.9.9b.  He wasn't planning on
putting it up on the Web (wait a bit until we have a few more
features/fixes), but will if there is a need.
