Getting Started


Portability was a major concern during design and implementation of Hopper. To ensure that it would be widely available on a variety of platforms, we chose the Java programming language as the implementation vehicle. As a result, Hopper can be run on virtually any host that supports modern versions of Java, including most variants of Unix, Mac OS X, and Windows.

Hopper can be run on any of LLNL's production computing hosts simply by typing "hopper" at the command line. (Note that PC users must first run X-Win 32 or equivalent, and Mac users must first start the X11 application.) LLNL users can download Hopper for their local systems from

Hopper's source code will soon be obtainable from this site. At that time Hopper can be freely used and distributed.
