HP-UX Operating System
HP-UX on the V2500/V2600
• Fill First—Fill a locality first, then spill over to another locality, as
needed. Once all localities are filled, start over as needed.
• Packed—Place all threads or processes in the same locality; do not
spill over.
• Least Loaded—Place each thread or process in the locality that is
least-loaded at the time of its creation.
Gang scheduling of threads and processes is supported through the
mpsched -g option and the MP_GANG HP-UX environment variable.
Details are provided in the gang_sched(7) man page and in the
section “Process and Thread “Gang Scheduling”” on page 122.
More details about HP-UX programming, scheduling, and launch
enhancements are available in the HP-UX V11.10 online man pages and
in the HP-UX SCA Programming and Process Management White Paper.
