-m "host_name host_group ..."

Changes the list of hosts for which job slots specified with -nare reserved. At job submission, LSF considers the hosts in the specified order.

If you also specify a resource requirement string with the -Roption, -mis optional.

The hosts can be local to the cluster or hosts leased from remote clusters.

-njob_slots Changes the number of job slots to reserve. job_slots must be less than or equal to the actual number of sltos for the hosts selected by -mor -Rfor the reservation.

If you also specify the reservation for system use with the -soption, -nis optional.

-R "res_req" Changes the host selection for the reservation according to the specified resource requirements. Only hosts that satisfy the resource requirement expression are reserved. -Raccepts any valid resource requirement string, but only the select string takes effect.

If you also specify a host list with the -moption, -Ris optional.

Platform LSF.

The size of the resource requirement string is limited to 512 bytes.

-ttime_window Replaces the time window with a new one to shift a recurring reservation. You cannot modify the start time of a recurring reservation that has current active instance.

To specify a time window, specify two time values separated by a hyphen (-), with no space in between:

time_window = begin_time-end_time

Times are specified in the format:

[day:]hour[:minute]

where all fields are numbers with the following ranges:

◆day of the week: 0-6 (0 is Sunday)

◆hour: 0-23

◆minute: 0-59

Specify a time window one of the following ways:

◆hour-hour

◆hour:minute-hour:minute

◆day:hour:minute-day:hour:minute

The default value for minute is 0 (on the hour); the default value for day is every day of the week.

You must specify at least the hour. Day of the week and minute are optional. Both the start time and end time values must use the same syntax. If you do not specify a minute, LSF assumes the first minute of the hour (:00). If you do not specify a day, LSF assumes every day of the week. If you do specify the day, you must also specify the minute.

You can specify multiple time windows, but they cannot overlap. For example:

timeWindow(8:00-14:00 18:00-22:00)
