SYNOPSIS

       rt_server  [-hV]  [-o  ior-file]  [-m manager-ior] [-P period] [-f run-
       time] <-t task-ior|-n name> [compute1 [compute2 ...]]

DESCRIPTION

       The rt_server utility exports a CORBA object that  generates  synthetic
       computing  load  when  periodically driven by the rt_client(1) command.
       Its primary purpose is to serve as an interesting process that the  CPU
       Broker  can manage.  The process communicates with the Broker using the
       task object specified by -t or creates its own  if  -n  is  used.   The
       actual amount of CPU it consumes in a given period is determined by the
       computeN arguments.  These arguments specify a loop of time values that
       determine  how  much  of  the period it should spend consuming the CPU.
       The values can be a number with units  (e.g.  "60000000us",  "60000ms",
       "60s", or "1m") or without, in which case it is assumed to be microsec-
       onds.  When a period completes, it will switch to the next value in the
       sequence.   The  default sequence oscillates between consuming half the
       period and a quarter of the period.

       Available options:


       -h     Print out a usage message.

       -V     Print out a version number.

       -o ior-file
              The output file for the object's IOR. (Default: ./rtserver.ior)

       -m manager-ior
              The Broker::Manager IOR for this machine.  (Default: file://man-
              ager.ior)

       -P period
              The period of the process.  The value can be a number with units
              (e.g. "60000000us", "60000ms", "60s", or "1m")  or  without,  in
              which  case  it is assumed to be microseconds.  (Default: 1 sec-
              ond)

       -f run-time
              The amount of time to run for.  The value can be a  number  with
              units (e.g. "60000000us", "60000ms", "60s", or "1m") or without,
              in which case it is assumed to be microseconds.  (Default:  for-
              ever)

       -t task-ior
              The  IOR  for the Broker::RealTimeTask that has been created for
              this process.  This is incompatible with the -n option.

       -n name
              The name to use when creating a  Broker::RealTimeTask  for  this
              process.  This is incompatible with the -t option.

EXAMPLES

       To start a process with a period of half a second and consumes 100 mil-
       liseconds and 125 milliseconds every other period.

              [nemo@anemone rbroker] rt_server -n rt1 -P 500ms 100ms 125ms

       Now to drive that process we start a client:

              [nemo@anemone rbroker] rt_client -P 500ms
