Hi Roland,
Maybe the pbsnodes give
the ntype cluster info. You :

It seems the head node get
the different domain. In the /etc/hosts

But I don’t how tell the
pbs_server he should use the cluster.local. J thanks!

[torqueusers] how to get Environment Variables
Hi Chaucer,
beside our production system we have a test system with two nodes.
One of them is server,
but I can run jobs with qsub -l nodes=2.
Do all your nodes have the "ntype" "cluster"?
Regards,
Roland

Subject: ??: [torqueusers] how to
get Environment Variables
Hi Roland,
The Environment variables problem is OK now. but I encounter
another problem:
There are four nodes including the head node. But I only can submit
3-node job by qsub. When I submit a 4-node job it gives:
c0-0
c0-1
c0-2
cluster
totalnum=4 numhosts=3
there are not enough hosts on which to start all processes
1. no mpd is running on this host
2. an mpd is running but was started without a
"console" (-n option)
mpdtrace: cannot connect to local mpd (/tmp/mpd2.console_ccao);
possible causes:
mpdallexit: cannot connect to local mpd (/tmp/mpd2.console_ccao);
possible causes:
1. no mpd is running on this host
2. an mpd is running but was started without a
"console" (-n option)
It seems I can’t run the job on head node(cluster) with pbs. But I
can run 4-node job directly (without qsub).
When I use pbsnodes to check it seems all nodes are in free status.
Can you help me on this? Many thanks!
Best wishes,
Chaucer

Hi Chaucer,
Could you provide the part of your script, which
is reading PBS env variables?

Environment Variables
Hi all,
Does any one know how can
I get the the PBS environment variables in the run script file. When I qsub my
script file it gives:
PBS_NODEFILE: Undefined
variable.
PBS_ENVIRONMENT: Undefined
variable.
Many thanks!
Chaucer
