[Beowulf] picking out a job scheduler

[Nathan Moore]

Torque was really easy to install, but it seems like my /etc/hosts  
file must be screwed up, as I can't get the cluster nodes to  
respond.  Specifically, within a cluster of 3 machines, each having  
an /etc/hosts file of:

	127.0.0.1       localhost.localdomain   localhost
	199.17.152.17   runner
	199.17.152.135  muscovey
	199.17.152.13   pekin
	(( other workstations follow ))

Now, when I have the pbs_server running on runner, and the pbs_mom  
daemons running on muscovey, pekin, and runner, I et the following  
status message,

	[root at runner torque-2.1.6]# pbsnodes -a
	pekin
	     state = down
	     np = 1
	     ntype = cluster

	muscovey
	     state = down
	     np = 1
	     ntype = cluster

	runner
	     state = down	
	     np = 1
	     ntype = cluster

I realize this is a pretty low-level question, but what the heck is  
wrong with my /etc/hosts file?

regards,

NT


ps,  the trouble shooting message given by torque is,

	[root at runner torque-2.1.6]# momctl -d 3

That's correct, it (and ANU-PBS, another fork) seem to be the defacto  
queuing
systems in the state and national HPC centers down here.

Torque is just *so* much better than OpenPBS used to be (not that it was
particularly hard).

cheers,
Chris
