| < < | What if you want to change the number of available matlab licenses, urgent queues or CPLEX instances? You would be tempted to go into "complex configuration" and change the value "default" on the consumable's definition. However, this would break everything, so don't do it! Instead, go to "Host configuration", then choose the "execution host" tab and select the host "global". Then under "consumables/fixed attributes" you'll see the consumables: matlab, cplex, urgent. Change the totals here! | |||||||
| > > | What if you want to change the number of available matlab licenses, urgent queues or CPLEX instances? You would be tempted to go into "complex configuration" and change the value "default" on the consumable's definition. However, this doesn't work. (I think all this does is determine how many units of the consumable get used by requests to use the consumable that don't specify a number of units.) Instead, go to "Host configuration", then choose the "execution host" tab and select the host "global". Then under "consumables/fixed attributes" you'll see the consumables: matlab, cplex, urgent.

| The 'matlab-7.2' part may change as new versions of matlab become available... | ||||||||
| Added: | ||||||||
| > > | There are 22 CPLEX licenses bought as part of the CFI grant that purchased the cluster. Unless the department buys more someday, that's it... If you want to create a new consumable, you do want to go to "complex configuration". Give it a name and nickname, make it "int" and "<=", consumable, requestable and unforced, default=0. Then set the number of available units through host configuration as above. | |||||||
Maximum array job instances and tasks | ||||||||
| Changed: | ||||||||
| < < | These variables (max_aj_instances and max_aj_tasks) are in cluster configuration. Max_aj_instances used to be 20,000; KLB changed it to 100,000 on 10/13/06 because we seemed to have hit the maximum. Max_aj_tasks is 1,000,000. | |||||||

Max_aj_instances used to be 20,000; KLB changed it to 100,000 on 10/13/06 because we seemed to have hit the maximum. (This made the cluster essentially unresponsive for about an hour afterwards; I'm not sure it was a good idea...) Max_aj_tasks is 1,000,000. | |||||||
