[edit] tutorial
This is an outline of a future tutorial.
[edit] general info
- Monitor cluster status with ganglia
- use ssh to enter the cluster
- use ssh or rsh to get between nodes if necessary
- use MPI to program and start your job if appropriate
- use Xming or similar to access the system from windows if you need graphics
[edit] specific info
(These should probably be expanded--ask if you need details.)
- Use the batch queue systems appropriate for your cluster to schedule your jobs, such as Lava or Sun grid engine
- Watch out for hidden performance penalties if hyperthreading is enabled.
- your job can be optimized in various ways.
- please use ganglia to make sure your job is not left running accidentally and does not interfere with others' jobs.
- Be aware of disk quotas, move files to an appropriate storage location (or delete) when you are done with them.
