CPU Limit on Linux servers

The default limit of CPU time is 1200 seconds (20 minutes).  This can be increased in your shell control file.  In order to increase this time, follow these instructions:

  • open the .cshrc file in your home directory with your favourite editor
    • e.g. change limit cputime from 1200 to, for example, 10800 (3 hours), or unlimited
    • e.g. change limit memory from 1000megabytes to, for example, 20000megabytes, or unlimited
  • stacksize and datasize are other values that may need modification if your application hits limits
  • log out and log back in again for changes to take effect
