Are NODES and NODELIST the only env vars that BProc uses (I
gleaned this info from
http://asci-training.lanl.gov/BProc/)?

MTT is set up to detect environment variables and hostfiles
used by Slurm, PBS, N1GE, and LoadLeveler and set a max
value for -np based on those env vars.  While we add the
smarts to MTT to do that for BProc, you could also hardcode
the -np value (e.g., 2) in your ini's "MPI Details" section
like so:

exec = mpirun @hosts@ -np 2 --prefix _prefix() _executable() 
_argv()

Do you access the web through a proxy server? If so, you
need to set your http_proxy/https_proxy env var(s) to that
proxy.

I take it you *do* know your password, but just didn't email
it to the list.

This won't effect your connectivity with the mtt database,
but you probably want to do something like:

mttdatabase_platform = lanl
