• Keyword descriptions

  CYCLE
  	CYCLE
  	If farming should process all jobs in a cyclic way, stopping only if MAX_JOBS_PER_GROUP is exceeded.
  	This optional keyword cannot be repeated and it expects precisely one logical.
  	The lone keyword behaves as a switch to .TRUE.
  	Default value: .FALSE.

  DO_RESTART
  	DO_RESTART
  	Restart a farming job (and should pick up where the previous left off)
  	This optional keyword cannot be repeated and it expects precisely one logical.
  	The lone keyword behaves as a switch to .TRUE.
  	Default value: .FALSE.

  GROUP_PARTITION
  	GROUP_PARTITION 2 2 4 2 4
  	gives the exact number of processors for each group.
  	This optional keyword cannot be repeated and it expects a list of integers.

  GROUP_SIZE
  	GROUP_SIZE 2
  	Gives the preferred size of a working group, groups will always be equal or larger than this size.
  	This optional keyword cannot be repeated and it expects precisely one integer.
  	Default value: 8

  MASTER_SLAVE
  	MASTER_SLAVE
  	If a master-slave setup should be employed, in which one process is used to distribute the tasks. This is most useful to load-balance if not all jobs have the same length, and a lot of CPUs/groups are availabe.
  	This optional keyword cannot be repeated and it expects precisely one logical.
  	The lone keyword behaves as a switch to .TRUE.
  	Default value: .FALSE.

  MAX_JOBS_PER_GROUP
  	MAX_STEP 4
  	maximum number of jobs executed per group
  	This optional keyword cannot be repeated and it expects precisely one integer.
  	Default value: 65535
  	Alias names for this keyword: MAX_JOBS

  NGROUPS
  	NGROUPS 4
  	Gives the preferred number of working groups.
  	This optional keyword cannot be repeated and it expects precisely one integer.
  	Alias names for this keyword: NGROUP

  RESTART_FILE_NAME
  	RESTART_FILE_NAME <FILENAME>
  	Name of the restart file to use for restarting a FARMING run. If not specified the name is determined from PROJECT name.
  	This optional keyword cannot be repeated and it expects precisely one string.

  WAIT_TIME
  	WAIT_TIME 0.1
  	Time to wait [s] for a new task if no task is currently available, make this zero if no clock is available
  	This optional keyword cannot be repeated and it expects precisely one real.
  	Default value: 5.00000000E-01
