schedctl


Overview:

   The 'schedctl' command controls various aspects of scheduling behavior. It is used to manage scheduling activity, kill the scheduler, and create resource trace files.
 

Format:

    schedctl { -k | -n | -r [ <RESUMETIME> ] | { -s | -S } [ <ITERATION> ] }
 

Flags:

   -k

      shutdown the scheduler at the completion of the current scheduling iteration

   -n

      dump a node table trace to <STDOUT> (for use in simulations)

   -r [ <RESUMETIME> ]

      resume scheduling in <RESUMETIME> seconds or immediately if not specified

   -s [ <ITERATION> ]

      suspend scheduling at iteration <ITERATION> or at the completion of the current scheduling iteration if not specified. If <ITERATION> is followed by the letter 'I', maui will not process client requests until this iteration is reached.

   -S [ <ITERATION> ]

      suspend scheduling in <ITERATION> more iterations or in one more iteration if not specified. If <ITERATION> is followed by the letter 'I', maui will not process client requests until <ITERATION> more scheduling iterations have been completed.

Example:

Shut maui down

> schedctl -k

maui shutdown
 

Example:

Stop maui scheduling

> schedctl -s

maui will stop scheduling immediately
 

Example:

Resume maui scheduling

> schedctl -r

maui will resume scheduling immediately
 

Example:

Stop maui scheduling in 100 more iterations. Specify that maui should not respond to client requests until that point is reached.

> schedctl -S 100I

maui will stop scheduling in 100 iterations
