| + | ==== Exemple ==== | ||
| + | Si on considère une liste de jobs alloués dans la file de plus basse priorité, ALL : | ||
| + | <code> | ||
| + | root@cluster-head:~# squeue -l | ||
| + | Mon Feb 22 15:06:28 2016 | ||
| + | JOBID PARTITION NAME USER STATE TIME TIMELIMIT NODES NODELIST(REASON) | ||
| + | 2115 K20 bash scaminad RUNNING 54:49 UNLIMITED 1 cluster-r720-k20-1 | ||
| + | 2131 all MPI IDL abeelen RUNNING 0:59 UNLIMITED 1 cluster-r820-2 | ||
| + | 2130 all MPI IDL abeelen RUNNING 1:27 UNLIMITED 1 cluster-r820-1 | ||
| + | 2128 all MPI IDL abeelen RUNNING 5:30 UNLIMITED 1 cluster-r730-k20-1 | ||
| + | 2125 all MPI IDL abeelen RUNNING 23:07 UNLIMITED 1 cluster-r720-phi-2 | ||
| + | 2124 all MPI IDL abeelen RUNNING 24:14 UNLIMITED 1 cluster-r720-phi-1 | ||
| + | 2123 all MPI IDL abeelen RUNNING 23:05 UNLIMITED 1 cluster-r720-k20-2 | ||
| + | 2122 all MPI IDL abeelen RUNNING 26:42 UNLIMITED 1 cluster-r720-2 | ||
| + | 2121 all MPI IDL abeelen RUNNING 27:28 UNLIMITED 1 cluster-r720-1 | ||
| + | </code> | ||
| + | Et qu'on fait une allocation dans une file de priorité supérieure à celle de ALL : | ||
| + | <code> | ||
| + | root@cluster-head:~# salloc -N 2 -p K20 --exclusive | ||
| + | salloc: Granted job allocation 2132 | ||
| + | root@cluster-head:~# squeue -l | ||
| + | Mon Feb 22 15:06:40 2016 | ||
| + | JOBID PARTITION NAME USER STATE TIME TIMELIMIT NODES NODELIST(REASON) | ||
| + | 2132 K20 bash root RUNNING 0:04 UNLIMITED 2 cluster-r720-k20-2,cluster-r730-k20-1 | ||
| + | 2115 K20 bash scaminad RUNNING 55:01 UNLIMITED 1 cluster-r720-k20-1 | ||
| + | 2131 all MPI IDL abeelen RUNNING 1:11 UNLIMITED 1 cluster-r820-2 | ||
| + | 2130 all MPI IDL abeelen RUNNING 1:39 UNLIMITED 1 cluster-r820-1 | ||
| + | 2125 all MPI IDL abeelen RUNNING 23:19 UNLIMITED 1 cluster-r720-phi-2 | ||
| + | 2124 all MPI IDL abeelen RUNNING 24:26 UNLIMITED 1 cluster-r720-phi-1 | ||
| + | 2122 all MPI IDL abeelen RUNNING 26:54 UNLIMITED 1 cluster-r720-2 | ||
| + | 2121 all MPI IDL abeelen RUNNING 27:40 UNLIMITED 1 cluster-r720-1 | ||
| + | 2128 all MPI IDL abeelen SUSPENDE 5:38 UNLIMITED 1 cluster-r730-k20-1 | ||
| + | 2123 all MPI IDL abeelen SUSPENDE 23:13 UNLIMITED 1 cluster-r720-k20-2 | ||
| + | </code> | ||
| + | Les 2 jobs qui tournaient sur des machines de la file K20 se retrouvent suspendus. | ||
