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 talk, 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, I’ve carried CRAY-1 logic design to both MySQL table design and PHP coding. After this talk, you will as well.

Fun talk discussing some core concepts that often get overlooked. It was very interesting to learn how the CRAY-1 worked. Great enthusiasm, audience participation, and insights give. I highly recommend attending this talk if given again!

I like the material shared, the examples, and to know about the past too, the differences between the cray-1 hardware functionalities agains PHP functions. Also, it's evident that Ed enjoys giving this talk more than anyone else, he puts passion on it.
