I'm trying to package GNUBatch for OpenCSW [1]. I've created a package and installed GNUBatch quite successfully. I can start it, run jobs with gbch-r and they're executed. I even get an email about it every time.

Now, the question is how do I get it to run the job on other nodes? I've been through the manuals but haven't been able to find much info on the subject. I can't find much info on how to create different queues, only how to write expressions to select them.



You firs need to have each other node set up so it sees "exported" jobs and variables from its peers - you should be able to change job parameters remotely etc.

You may have to run gbch-hostedit to set up other nodes' IP addresses and stop/restart the scheduler.

I think I've got the host file correctly configured. When I'm in gbch-hostedit I can see the (correct) IP of the host.

However, I'm not sure how to verify the file and the connection to the other hosts.

This is my setup:

$ cat /opt/csw/etc/gnubatch.hosts
# Host file created on 24/09/09 at 18:59:19

skybert-6       s6      probe,manual,trusted

When I'm trying to access a variable on a remote node (assuming this is the correct syntax) I'm getting:

$ gbch-var skybert-6:CLOAD
gbch-var: Unknown variable skybert-6:CLOAD

I did try to run "gbch-conn skybert-6" which seemed to work just fine after switching the connection type to manual.

Are there any log files I can look at?
