Job Limits

Each LC platform is a shared resource. Users are expected to adhere to the following usage policies to ensure that the resources can be effectively and productively used by everyone. You can view the policies on a system itself by running:

Web version of Mica

There are 5 generally available machines on the SCF. Please consider your needs to decide which machine is best for your flavor of work.

• Agate—a 48 node machine for up to 36 core jobs (no interconnect)
• Mica—a small machine for debugging (8hr job limit)
• Jadeita—a machine for small jobs
• Magma—a machine for small to medium jobs
• Jade—a machine for large jobs (4 jobs/user limit)

Mica is now in General Availability mode and all jobs are scheduled per node in two pools. Remember you can run using qos=standby to get additional resources if there are a lot of empty nodes.

• pbatch—290 nodes (10440 cores), batch use only
• pdebug—16 nodes (576 cores), debug use only.
• pvis—67 nodes (2412 cores), interactive / visualization work.

Pools Max nodes/job Max runtime
---------------------------------------------------
pbatch 32 8 hours
pdebug 8(*) 2 hours
pvis 32 4 hours
---------------------------------------------------

NOTE: there is also a limit of 48 nodes per user per bank. This limit is aggregated across all of a users jobs on mica: pbatch + pdebug + pvis.

(*) pdebug is for debugging and other interactive work.

• Jobs are node scheduled
• Limit your work to 8 nodes on a per user basis.
• Do not use pdebug for production work or chain jobs
• Using more than these limits can result in job removal without notice.
