Big Iron: PHP Lessons from Cold War Supercomputing

Edward Barnard Beginner

The original CRAY-1 Supercomputer was a 5-ton monster with just 8 MB of main memory, yet programming it can be a fun way to explore subtleties of PHP coding. In this session we indulge in programming "big iron" on "bare metal."  We’ll look at CRAY-1 hardware instructions with the aim of understanding logic operations, boolean algebra, and octal arithmetic. As a Cray Research veteran, Edward has carried CRAY-1 logic design to both MySQL table design and PHP coding. After this session, you will as well.
