Re: [Mars-sim-users] Mars-sim profiling project

[Scott D. <mar...@gm...>]

Hi Jake,

I'm sorry the sim has been running so slowly on your machine.  It's
been a while since I've tried it using OpenJDK 6; my normal
development/testing environment is Ubuntu 10.04 with Oracle/Sun Java
1.6 (usually through Eclipse).  I'll do some run tests with the
OpenJDK to see if there are significant performance differences.

There is indeed a memory leak bug in version 3.01 (the last stable
release) in which the old simulation is not properly cleared out of
memory when a new simulation is created or loaded.  This bug is fixed
in the current development build, along with some performance
improvements.  I still plan on trying to improve the application
performance for the next release (I've been using the VisualVM
profiler that comes with the Oracle/Sun JDK).

You may want to check out the latest development version of the
project from the subversion code repository.  The project uses maven
as a build tool, and can be set up in Eclipse (with plugins) or built
through the command line.

The subversion code repository check out info is here:
http://sourceforge.net/scm/?type=svn&group_id=3286

If you want to set up an Eclipse development environment, this is the how-to:
http://sourceforge.net/apps/mediawiki/mars-sim/index.php?title=Getting_Started_with_MSP

If you'd like to set up a command line development environment, you'll
need subversion and maven installed on your system (through ubuntu
apt-get).  Check out from the code repository, then run the following
maven goals to compile, install, and run the program:
mvn compile
mvn install
cd mars-sim-min
mvn exec:java -Dexec.mainClass="org.mars_sim.msp.MarsProject"

The sim can also be run headless (without the UI) with the -headless
argument.  This may be useful for profiling.

I hope this is useful to you.  Please let me know if you have any
questions or run into problems.
