Re: [BProc] bproc 4.0 bproc_nodeinfo issue

[Luke <lo...@du...>]

You may want to note that -3 means BPROC_NODE_NONE.  From my debugging 
runs, on the first pass through that loop you're getting back garbage in 
the string from bproc_nodestatus.

I definitely agree with Greg as well-  Unless there's something about 
LAM on bproc that I'm missing, it would be bad to require that parallel 
processes are present on the master.
