Resource Limits in the FastX Environment

Limits are imposed on users and processes by the system to ensure equal access to the shared FastX servers. In particular we limit the maximum number of processes per user, the maximum amount of virtual and resident memory per process, and the amount of CPU consumed per process.

Current limits are as follows:

resource limit description
nproc 15556 maximum number of processes
cpu 4320

minutes of cpu time per process

rss 16GiB

maximim in memory size of any one process

as 96GiB maximum virtual size of any one process


These limits are "hard" limits meaning that once the limit is reached the process will be killed.  To see the limits under which you are currently operating you can run the ulimit command from a shell.
