can be used with the -T

, -p, -c, and -l options. policy is one of the following values.

RR Round robin launch policy. Under this policy, successive direct child processes of

the speciﬁed command or process are launched in a round robin fashion across the

other locality domains in the system relative to creating process.

RR_TREE Tree based round robin launch policy. Under this policy, successive child

processes and their descendents are launched in a round robin fashion across the

other locality domains in the system relative to creating process.

LL Least loaded launch policy. Under this policy, child processes are launched on the

least loaded locality domain in the system at the time of creation.

FILL Fill ﬁrst launch policy. Under this policy, successive direct child processes of the

speciﬁed command or process are launched on the same locality domain as their

parent until one has been launched on each processor in the locality domain. At

that point, new processes are created on the next locality domain.

FILL_TREE

Tree based Fill ﬁrst launch policy. Under this policy, successive child processes

and their descendents are launched on the same locality domain as their parent

until one has been launched on each processor in the locality domain. At that

point, new processes are created on the next locality domain.

PACKED Packed launch. Under this policy, successive processes are launched on the same

locality domain as their parent. A different domain is never selected.

NONE No special policy. The default HP-UX launch policy is used.

-T policy Apply the speciﬁed policy to the threads of the process. The scheduling policies are the same

as for the -P option except that they apply to newly created threads instead of processes.

Also, thread policies can only be speciﬁed on commands launched from the command line of

mpsched. The option can be used with the -P, -l, and -c

options.

Operands

The command-line operands are:

command A command including its arguments.

RETURN VALUE

mpsched returns exit status 0 if command is successfully scheduled or -1 if it fails.

EXAMPLES

Execute the a.out ﬁle on processor 2:

mpsched -c 2 a.out

Set the process launch policy for the existing process with pid 24217 to round robin:

mpsched -P RR -p 24217

Bind the processes with pids 1247 and 1842 to processor 4:

mpsched -c 4 -p 1247 -p 1842
