We should have this number in the config file. So when Administrator enter server config file (config_processing.php), each server should have the max processing number go with it.

Thanks.

You may want to determine this from the cluster itself. You can query various info using commands such as:
qmgr -c "list queue @guppy"
qmgr -c "list node @guppy"
(or pbsnodes command is similar)

This will tell you the number of nodes, number of processors per node, which processors are currently in use, how much memory, wall time, etc. it available. It can give a lot of information that the user may want to know before submitting a job. For instance, if only three out of four nodes are free, then you may want to submit a job for three nodes rather than wait for all four to become free. Also, if a node needs to be taken down for maintainance, the web page would automatically be updated with the max nodes available, preventing a job request from being queued indefinitely because too many nodes were requested.

You may still want extra control on top of that, for instance, restricting users to less than the maximum number of nodes/procs available. Probably best to configure those types of restrictions on the server (qmgr) and then let the user query what resources are available to them. This would also be ideal in the case where you may want to give certain users more/less restriction than others. You can set up multiple queues where each one has different resource allocations.

Eric will add this field to the config file for now (getNumberofProcer). We will return to this issue after the 2.0 release. Please do not Close this issue OR create a new one for the Dynamic option.

For now, we change the Global variable $PROCESSING_HOST to an array holding the name of the host pair with the number of processing nodes. (example provided in the config.php.template).

To test this: edit your config file. Add more than 2 processing host.
Select any tools in image processing pipeline.
You should see a list of hosts show up.
and select processing node more than the number setup in the config file.
You should get an error.

Thanks.

My favorite command is:

pbsnodes -a | egrep "resources_available.(mem|ncpus)" | sort | uniq -c
