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

Bind the Lightweight Processes with lwpids 12345 and 12346 to locality domain 2:

mpsched -l 2 -G 12345 -G 12346

Print the processors in the same proximity set as processors 0 and 4:

mpsched -b 0 4

Print the system topology at the locality domain, proximity set, socket, core and processor level:

mpsched -S
