Usage statistics 2016

General Statistics

Number of jobs

Cluster	Number of processed jobs
Euler	|21,710,509
Brutus	|24,624,958
|Total	|46,335,467

Number of users*

Cluster	Number of users
Euler	|2,020
Brutus	|717
|Total	|2,311

* Only users that submitted at least one job were counted. Double countings from users that used both clusters have been removed in the total.

Number of support requests**

Support channel	Number of support requests
OTRS ticket system	|1,332 (1,767)

** The total number of support requests in 2016 is larger than the number shown in this table, as not all support requests were handled through OTRS. The fist number includes all SIS::HPC queues and the number in parenthesis also includes the ticket from the SIS top level queue, which will no longer be included from 2018 on.
