 This table shows cluster cpu/memory usage for ''qsub'' jobs in terms of "Slot Equivalent Time" by periods of 'day' and 'division'. ''qlogin'' jobs/sessions are not reported. This table shows cluster cpu/memory usage for ''qsub'' jobs in terms of "Slot Equivalent Time" by periods of 'day' and 'division'.

-The goal of this report is to help with deciding what how many slots per "High-speed Project Slot Quota" to request for your group. For a discussion on slots and Project Slot Quotas, [[cluster_billing#slot_groups|click here]]. Note that slots are added to Project Slot Quotas in increments of 16, so there is a 16-slot minimum for a High-speed Project Slot Quota.+The goal of this report is to help with deciding what how many slots per "High-speed Project Slot Quota" to request for your group.

 +Quick notes on slots and Project Slot Quotas: 
 + 
 +  * A "slot" is a cpu core and 6GB of RAM (3GB on the basic nodes). 
 +   
 +  * Each Group/Lab/Billing-Entity has a "Basic Project Slot Quota" as a part of the required Basic Account. See the link above for details. This report is meant for deciding how many slots to choose for the optional "High-speed" Project Slot Quotas. 
 + 
 +  * A user can be in any number of different Project Slot Quotas, and can be in Project Slot Quotas that belong to different Group/Lab/Billing-Entities.  
 + 
 +  * Users can have different per-user slots quotas within a Project Slot Quota. 
 + 
 +  * Slots are added to Project Slot Quotas in increments of 16, so there is a 16-slot minimum for a High-speed Project Slot Quota.
  
 __NOTE__ Project Slot Quotas will be put into use very soon. Once this is done, each job will be assigned to an SGE project (with the same name as a Project Slot Quota) to track and limit resources by Project Slot Quota. For users who work with multiple groups or labs, this means their quotas will then be set based on the project they assign to their jobs, allowing them to work flexibly with multiple labs. However, the report below is from jobs that do not include that information, so users who work within multiple groups have their usage below reported only as a part of their 'home' group/lab. __NOTE__ Project Slot Quotas will be put into use very soon.

 The "Slot Equivalent Time" (SET) is the period of time a job runs, multiplied by the SE of the job, reported in units of days or 'divisions'. The "Slot Equivalent Time" (SET) is the period of time a job runs, multiplied by the SE of the job, reported in units of days or 'divisions'.
