The new way of calculating fairshare

The new way of calculating fairshare

Dear users,

We would like to inform you that starting from Thursday, March 9th, 2023, we are changing the method of calculating fairshare. We are adding a new coefficient called "spec", which takes into account the speed of the computing node on which your job is running.

Until now, "usage fairshare" was calculated as  usage = used_walltime*PE , where "PE" represents processor equivalents expressing how many resources (ncpus, mem, scratch, gpu...) the user allocated on the machine.

From now on it will be calculated as usage = spec*used_walltime*PE , where "spec" denotes the standard specification of the main node (spec per cpu) on which job is running. This coefficient takes values from 3 to 10.

We hope that this change will allow you to use our computing resources even more efficiently. If you have any questions, please do not hesitate to contact us.
