==== Openlava Elim ====

Pulling some information together for Openlava users documenting the ability to write your own monitor resources which the scheduler will then manage. This is handy so jobs go in PENDing mode while waiting for custom resoures to become available instead of crashing immeditaley upon submission.

  * Old example reporting local and network based scratch space availability.
    * Written because NFS does file locking poorly, hence /localscratch, does not have to be large.
    * What the heck is an [[cluster:49|eLIM]]?

  * Newer example showing the integration of GPU availability into Openlava using eLim.
    * [[cluster:119|Submitting GPU Jobs]]

  * Example of managing licenses.
