yeah, know that you mention it, i remember (old brain here, as well)
But IIRC you created a OMPI version which was called 1.4a1r or something,
where i indeed could use this xterm. When i updated to 1.3.2, i sort
of forgot about it again...

Another question though:
You said "If it includes the -xterm option, then that option gets
applied to the dynamically spawned procs too"
Does this passing on also apply to the -x options?

Thanks
