I'm trying to get PVM to spawn processes on remote workstations on a LAN
comprised of SGI workstations running IRIX v5.2.  pvm_spawn refuses to spawn
processes on any but my own workstation.  The /tmp/pvml.xxxx file looks like
this:

	[t80040000] ready  3.3.7   Mon Jul 24 17:25:18 1995
	[t80000000] pl_startup() pvmd@delaware: EOF
	[t80000000] pl_startup() pvmd@iowa: EOF
	[t80000000] pl_startup() pvmd@utah: EOF
	[t80040000] startack() host delaware expected version
	[t80040000] startack() host iowa expected version
	[t80040000] startack() host utah expected version
	

I start up pvm via pvmd, type in the passwords, and then put it in the
background:

	pvmd pvm_hosts

The pvm_hosts file looks like this: 

	# PVM host file for parallel h.261 coder
	# Runs on SGI machines
	
	wisconsin	so=pw
	#alabama		so=pw
	#alaska		so=pw
	#florida		so=pw
	#maine		so=pw
	#nebraska	so=pw
	#missouri	so=pw
	delaware	so=pw
	iowa		so=pw
	#hawaii		so=pw
	#indiana		so=pw
	utah		so=pw

My workstation is wisconsin.

I tried forcing pvm_spawn to start processes on specific workstations
instead of letting it decide where to put things, but the pvm_spawn calls
fail with no explanation from pvm_perror; i.e., "Error: 0".

My ~/pvm3/lib is linked to the system pvm3.7.7/lib directory, so that
doesn't seem to be the problem.

Any help anyone can provide will be graciously accepted.  If you post a

Thanks!
