MasterSlave Schedule Override

This page documents how to override the MasterSlave job schedule for a workstation. It is of use for excluding MasterSlave jobs from a workstation for a period of time. Once the schedule override expires, the workstation will return to its default MasterSlave schedule.

Short and sweet

To exclude MasterSlave from running on a workstation named yourworkstation today and tomorrow,

run this command:
/proj/axaf/simul/bin/overrideSlave -H yourworkstation today tomorrow

Any MasterSlave jobs running on your workstation before you execute the above command line will finish running. No new jobs will be submitted.

There will be one process (per MasterSlave user) remaining on your workstation. This process is the client and tells MasterSlave not to submit any jobs during the time period requested. It can be identified by running ps -auxwww on your workstation; it is the executable MasterSlave.SlaveClient

    Additional days may be specified using the syntax specified in the Operands section.

    An alternative host may be specified using the -H option. See the Options section.
