New parameter in PBS: spec

New parameter in PBS: spec

Dear users,

it is now possible upon submission of computational job to define minimal CPU speed of the computing node, i.e. to make sure that the computing node the job will run on will have CPU of defined speed or faster. For this purpose a new PBS parameter spec is used. It's numerical value is obtained by methodology of https://www.spec.org/. To learn more about spec parameter usage, visit our wiki at https://wiki.metacentrum.cz/wiki/About_scheduling_system#CPU_speed.

Setting up requirement on CPU speed can make the job run faster, but it will on the other hand limit the number of machines the job has at it's disposal, which can result in longer queuing times. Please bear this in mind while using the spec parameter. 

Best regards,

your Metacentrum
