What is Aardvark?

Aardvark is a prototype visualization applet for IPPM Surveyor Data.

Where will it run?

It will run inside of any platform which supports java 1.1.6 or greater and Swing 1.1.1 or greater

Why won't it run inside of my browser?

Because the current implementations of java inside most browsers are deficient. Many support an older version of java, and most cannot be coerced to support Swing.

Also, Aardvark writes two files to your local filesystem. To run Aardvark as an applet would require you to drastically reduce your applet security model which would open serious security holes on your machine.

Why is so much of the data missing?

The Surveyor project has evolved with a variety of hardware and software components. Historic data is not available for all moments of the past.

Why is the cache size so small?

The default size of the cache was picked for environments with a limited amount of system resources (ram, swap). If you are running Aardvark on a phat box, feel free to increase the cache size. See the User Guide for more information.

Why do i keep getting "Java stack overflow error"'s or "Java out of memory error"'s?

Try adding "-ms64m -mx64m" to your java invocation line (if you are invoking Aardvark via "runnit.bat" under windows, add these arguments to the invocation line in that file).
