Dear Alan,
I have installed pbs (torque) on my headnode and when I tried to run pbsnodes
-a I only saw the server. I thought I should see all my nodes on the cluster.
See the output:
[EMAIL PROTECTED] ~]# /opt/pbs/bin/pbsnodes -a
isxp1313c.sims.cranfield.ac.uk
state = down
np = 2
ntype = cluster
[EMAIL PROTECTED] ~]#
Why is the state=down? In the manual it should be state=free.
Could it be because I used the following configurations for the command:
/opt/pbs/bin/qmgr
Qmgr: set server operators = [EMAIL PROTECTED]
Qmgr: create queue batch
Qmgr: set queue batch queue_type = Execution
Qmgr: set queue batch started = True
Qmgr: set queue batch enabled = True
Qmgr: set server default_queue = batch
Qmgr: set server resources_default.nodes = 1
Qmgr: set server scheduling = True
Qmgr: quit
Could it be that
Qmgr: set server resources_default.nodes = 1, should be:
Qmgr: set server resources_default.nodes = 9?
Please how can I view all the nodes in the cluster Alan?
Regards
Gokop

No. Don't do this, ever! As Charles Bacon pointed out to you in his
reply yesterday, you need to generate a grid proxy from your user
certificate from a normal user account, not as root. You do not want
to map a grid user to the root account or allow this kind of access.
Perhaps you could provide (off-line if needed) a description of what
you are trying to achieve with your grid test instance? If you would
like to get a quick start on a working test implementation of grid
technology, there are several excellent tutorials, including the
following:
http://www.globusconsortium.org/tutorial/
See especially Chapter 6.
If your goals are more widespread, for example trying to create a
virtual organization for work in a certain area, you might check into
the Open Science Grid, EGEE, GLite or other comprehensive
distributions aimed at this task.
Note for your certificates to be accepted for use in essentially any
major grid, you will need to obtain host and user certificates issued
by a certificate authority accredited by the International Grid Trust
Federation (IGTF), information for which is available at
http://gridpma.org
Note: my own project to build a state-wide grid has produced an easy-
to-install implementation of a subset of the Virtual Data Toolkit
implementation of GT4.x and a few other simple components,
information for which is available at the link
http://tigreportal.hipcat.net
Click on the link that says "Administrators" and then the tab for
"Server Stack Installation" for information on installing the server
components, or on the link that says "Documentation" then the tab for
"Client Stack Installation" for information on installing the
components typically used for client and job submission. (It is not
necessary to join the project to use this software stack, which was
designed to make an easy on-ramp for users and administrators to get
started with grid technology with the aim of joining larger
projects.) The VDT forms the basis for this implementation.
Hope this helps,
