Please do not flood the queues with a large number of jobs at the same time. The FairShare algorithm will generally ensure that every user and group gets the appropriate share of the computer by reducing the priority of jobs belonging to users/groups who have used more than their share in the recent past.

WebbJobs are scheduled on the HPC using Simple Linux Usage Resource Manager (SLURM) and resources allocated using the “Fairshare” algorithm to ensure fair access and allocation of resources to each user and College. Please note: These resources are only available to … WebbSLURM ¶ The tool we use to ... Each job’s position in the queue is determined through the fairshare algorithm, which depends on a number of factors (e.g. size of job, time requirement, job queuing time, etc). The HPC system is set up to support large …
WebbSLURM implements another factor of fairness such that not only the Raw Usage of an account is used to calculate the FairShare, but also the Raw Usage of its parent (i.e. the sum of all siblings). This allows that accounts of different parents with the same charged usage and the same shares, get different FairShare due to their sibling accounts.

WebbThe higher the priority your job is assigned, the more likely it is to run sooner. We have implemented the Slurm Fairshare feature. Basically, how this works is that the more you use Falcon - the lower priority your jobs have when compared to a user that has not been using as many compute resources. WebbYour current fairshare factor Each of these factors is normalised to a value between 0 and 1, is multiplied with a weight and the resulting values combined to produce a priority for the job. The current job priority formula on Tursa is: Priority = [10000 * P (QoS)] + [500 * P (Age)] + [300 * P (Fairshare)] The priority factors are:
WebbSlurm’s fair-share factor is a floating point number between 0.0 and 1.0 that reflects the shares of a computing resource that a user has been allocated and the amount of computing resources the user’s jobs have consumed. The higher the value, the higher is …
