In the previous exercise we showed how ecflow provides simple load management.

The limits can still allow several hundred jobs to be submitted at once. This can cause problems:

  • Excessive disk/io in job generation
  • Server busy in job generation, and slow to respond to the GUI.
  • Overload queueing systems like PBS/SLURM

Hence we need a load management that can limit the number of submission. When the Job becomes active the limit token is released.


We could have more than 2 active jobs, since we are only control the number in the submitted state.

If we removed the -s then we can only have two active jobs running at one time

This will allow the configuration of the suite, depending on the load the disk/io and queuing system can sustain.

Here is the simple illustration that modifies the previous example:

Let us modify our suite definition file:
