   LON-CAPA relies on an Intel-based architecture.  In order to
   move beyond this state of affairs, we are beginning to develop
   a BSD-based solution, as well as a set of diagnostic scripts
   which should verify LON-CAPA's performance on any computer platform.

   <p>
   For full-time, classroom usage, an adequate LON-CAPA server
   should be/have:
   </p>
   <ul>
   <li>a multiprocessor machine,</li>
   <li>a CPU speed of 1 gigahertz,</li>
   <li>a gigabyte of memory,</li>
   <li>and at least 40 to 80 gigabytes of hard disk space.</li>
   </ul>
   <p>
   A lesser machine can be used for toying around with LON-CAPA
   (LON-CAPA will run for a single user on most any machine).
   </p>
   <p>
   LON-CAPA servers experience significant peaks of activity
   before a homework submission deadline.  To support these critical
   peaks of activity, it is strongly advised that LON-CAPA machines
   fit the above recommendation.
   </p>
   <p>
   If thousands of students start accessing the box as a web server...
   you may want to consider more options.  The design of the LON-CAPA
   system is to naturally and transparently load-balance on multiple
   computer clusters.  So, a simple solution for running an entire
   college campus is to just have an adequate plurality of LON-CAPA
   servers rather than a single, particularly monstrous server.
   </p>
   <p>
   We like to think of high web server usage as "a good problem" though.. :)

   No.  The needs for predictable performance of a LON-CAPA system cause us
   to emphasize support on a restricted set of platforms.  We welcome developers
   who would like to create porting solutions, however based on our timeline,
   you are even more strongly encouraged to help develop the actual educational
   software technology seen by students and instructors.
