0.0.0.1 Manual Tuning

YAIM modules for TORQUE server don't configure all the parameters available for a queue. Several parameters must be set up manually otherwise default values (999999999) are published. The parameters are:

  • resources_default.walltime
  • resources_max.walltime
  • resources_default.cput
  • resources_default.pcput
  • resources_max.cput
  • resources_max.pcput
  • resources_default.procct
  • resources_max.procct
  • max_queuable
  • max_running
  • Priority

The following table shows how GLUE1 and GLUE2 attributes are calculated from the parameters above

GLUE1 Attribute GLUE2 Attribute Torque parameters and behavior
