GridPP DIRAC For SiteAdmins

Pilot Role

Please remember to enable the pilot role for all VOs supported by the GridPP DIRAC instance.
If you (as a site admin) notice a distinct lack of jobs submitted via the GridPP DIRAC instance, please contact Simon and Daniela at Imperial.

VAC/Vcycle

To enable automatic configuration of your VAC/Vcycle site, please create the following extension for the service in GOCDB:

PILOT_DN_GridPP <user_data_proxy DN>
PILOT_SE_GridPP <GridPP DIRAC SE NAME>

The update agent runs every 6 h. Please take this into account when doing updates.
Here is an example for the Imperial vcycle site.

GPU

GridPP DIRAC assumes that your GPUs have a dedicated queue per GPU type.
A discussed in the technical meeting, for each GPU queue create an extension tag to the CE: GPU_GridPP_<queue> with value <Software>_<Memory in GiB>[_EX] (note that queue may itself contain underscores).

Software: CUDA, OpenCL
Memory: Integer rounded down to the nearest GiB, zero is OK
_EX: runs in exclusive compute mode
An example would be, here for a Nvidia Tesla K40
GPU_GridPP_my_amazing_queue CUDA_11
