[Sunhelp] Processor Groups

[Vinay Bharel]

NAME
     pbind - control and query bindings of processes  to  proces-
     sors

SYNOPSIS
     pbind -b processor_id pid ...

     pbind -u pid ...

     pbind  [ -q ]  [ pid ... ]

DESCRIPTION
      pbind controls and queries bindings of processes to proces-
     sors. pbind  binds all the LWPs (lightweight processes) of a
     process to a processor, or removes or displays the bindings.

     When an LWP is bound to a processor,  it  will  be  executed
     only  by  that  processor  except  when  the  LWP requires a
     resource that is provided only by  another  processor.   The
     binding  is  not  exclusive,  that is, the processor is free
     execute other LWPs as well.

     Bindings are inherited, so new LWPs and processes created by
     a  bound LWP will have the same binding. Binding an interac-
     tive shell to a processor, for example, binds  all  commands
     executed by the shell.

     Superusers may bind or unbind any process, and  other  users
     can  use  pbind  to bind or unbind any process for which the
     user has permission to signal, that is, any process that has
     the same effective user ID as the user.
