ns2 simulator with gcc compiler using only 1 processor(?)
Hi!
I am using the ns2.31 simulator in Ubuntu 9.04.
I have developed my program and when I simulate it (calling ns2 from Ubuntu default shell, that uses gcc), I notice that only 1 of the 2 processors available in my notebook seems to be used (simulations are very heavy and my notebook stays around 25 minutes with the processor usage at 50%, but for example if I try opening firefox or open office, it requires minutes to do it and it blocks frequently).

I am not an expert and I'd like to understand why the processors are not at 100% (maybe only 1 of the 2 processors is used? Is there some way to force shell/gcc to use both?).

Maybe I didn't get the real problem, I hope someone can help!
Thank you a lot!!Smilie

NAME

       morse - A robotics simulator based upon the Blender Game Engine

SYNOPSIS

       morse [command] [options]

DESCRIPTION

       Morse,  the  Modular  OpenRobots Simulation Engine, uses the Blender Game Engine to provide a general purpose robot simulator.  A robot and
       its environment are defined in Morse by creating a model in Blender. Actuator and sensor objects are attached to a model, and may be inter-
       acted  with  via a variety of middleware protocols. Simulations can be programmed via Python scripts or inside of Blender itself. Currently
       supported middleware includes YARP, MOOS, ROS, Pocoslibs, as well as a plain socket interface.

COMMANDS

       [None] Launches the simulator interface with a default scene

       create filename
	      Creates a new empty scene and launches the simulator interface

       run filename
	      Runs a simulation without loading the simulator interface

       exec filename
	      Runs the given Python script with a default scene

       check  Checks the environment is correctly setup to run morse

       help   Displays information regarding the program

       version
	      Displays the version number
