Cluster Partitions

Tempest currently has the following partitions:

Partition
Descritpion
priority
The primary priority-access partition
unsafe
Preemptible partition with access to all unused CPU node resources
test
Partition for small test jobs
gpupriority
The primary priority-access GPU partition
gpuunsafe
Preemptible partition with access to all unused GPU node resources
gputest
Partition for small GPU test jobs
legacy
Fairshare partition with older hardware
nextgen
Fairshare partition with the newest hardware
nextgen-long
Same as nextgen, but with a longer max runtime
nextgen-gpu
Fairshare partition with the newest GPU hardware
 nextgen-gpu-long
Same as nextgen-gpu, but with a longer max runtime

 

For a more detailed description of the partitions, see the partition information.
