You can also set a default request in `qconf -mc` for complexes which can't be requested.

During execution of the job you can see it in `qstat -j <job_id>`, but in `qacct -j <job_id>` the reserved one is recorded. > 2.-) It talks about "reserved resources", but -l talks about > "requested" resources. So, do I have to force users to reserver > requested resources? Two words for the same. While it was most likely a clear statement in the past, with the introduction the advance reservation it could be misleading. But changing the name of the settings to read "*_REQUESTED_*" could make former cluster configurations invalid. You could even argue it should be "*_GRANTED_*". -- Reuti >> -- Reuti > Many thanks for your replies Reuti, > Arnau > > PS: do you know what has happen with gridengine.org domain and mailing > list? it has been un-available for few days.. > _______________________________________________ > users mailing list > [email protected] > https://gridengine.org/mailman/listinfo/users _______________________________________________ users mailing list [email protected] https://gridengine.org/mailman/listinfo/users
