 ===== Using the CfN Cluster =====
-See the other pages of this wiki for details on using the CfN cluster. This page is only to learn about differences between the PICSL and CfN clusters.

 Your username should be the same as on the PICSL cluster.

 This differs from the PICSL cluster data quotas, which are //per-user//. For now, quotas for the PICSL drives (/data/picsl, /data/tesla-data, /data/tesla-home) will remain unchanged, and per-user. At some point we'll merge these into per-project quotas for better management.
+===== Front-end Program/Process Limits =====
+Programs/commands/jobs/processes that are run on the front-end itself (chead) are limited to using 5GB of RAM, and 5 minutes of CPU time (not realworld time), at which point they are terminated. See [[ClusterBasics | Cluster Basics]]
 ===== Slots, Cores & Memory =====
 The CfN cluster handles slots, cores and memory differently. On PICSL, if you requested more slots, you got both more memory and more cpu cores. On CfN, the requests for these resources are separate. Please see [[using_ogs_sge#resources_memory_slots_cpu_cores|the details]] CfN cluster guide in the rest of the wiki.
