[BProc] Re: More LAM / BProc changes

[Daniel G. <dg...@ti...>]

Brian,

Success!!! (well, at least apparently).  The thing lamboots fine, starts
the lamd on all the nodes, and seems to run mpi jobs, so until further
testing it looks like we are in business!

I agree with you about BProc's lack of documentation, but I still like
the system.  It is the only cluster software that makes the cluster
seem like a single system image.  I have been running different versions
of it for over 2 years, and I insist on it for all my clusters.  It may
be time to hack on the BProc guys for more documentation (Erik...).

Anyway, thanks for your work on LAM, and let me know if I can be of more
help.

Regards,
Daniel
