To view and change the setup of hosts use qconf -XY [file] with the following options:. This is extremely important to set up for any cluster, to enable to limit the amount of memory that each job can request to avoid memory issues for user jobs. Then run qconf -Ap pe. Now smp can be used as a PE in the qsub argument. Next thing is to add the new PE smp into the all. The combination of the two more often than not means that SGE is not running on the compute node. E is a worse state to see.
It means that there was a major problem on the compute node with the system or the job itself. SGE intentionally marked the queue as state "E" so that other jobs would not run into the same bad problem.
E states do not go away automatically, even if you reboot the cluster. Once you think the cluster is fine you can use the "qmod" command to clear the E state.
When deleting a job, sometimes a "dr" will show up, indicating that the job is not running correctly and cannot be easily deleted. In this case, log in as "su", then "qdel " to delete the job forcefully. If it does not work, do "qdel -f " to delete the job. If a node continues to be in E state after clearing the error multiple times by qmod, then it is likely that there is a hardware error.
If you job fails in a node the node should show up as 'au' status in qstat , you can restart the job in a different node. Default value is intr,softload. This value cannot contain spaces. If this threshold is exceeded, a load critical alert appears in the Monitor.
Similar to the Load Warning parameter, you set this parameter in terms of the system load scaled by number of CPUs.
Default value is 3. If this threshold is exceeded, a load warning alert appears in the Monitor. Default value is 1. You set the value in hours. If the value drops below this threshold, a memory critical alert appears in the Monitor. You set the value in terms of megabytes of free virtual memory. If the value drops below this threshold, a memory warning alert appears in the Monitor.
You set the parameter value in terms of megabytes of free virtual memory. Once you deploy the master host, you cannot edit this value and it remains in effect for all further deployments of compute and submit hosts. You can edit this setting again only if you uninstall the master host.
When you deploy the master host using N1GE, this parameter is set automatically to the master host. If the master host has been previously deployed using N1GE, then the proxy host is set to this host and cannot be changed until the master is uninstalled.
