This is real hard work, Chris. U built every unit, the multiplier, the adder and the rest of alu stuff. These units are the most time consuming and difficult to debug too. Impressive. Whats ur next target.

Just visited the first Cray-1 (so they tell me) at NCAR in Boulder, CO. I threw a few photos up on a web page if anyone is interested at http://homepage.mac.com/cheilman/NCAR_Cray_1/. I grew up in Eau Claire just south of Chippewa Falls, WI where Cray Research was founded (and almost ended up working there years ago). I recall studying the architecture back in grad school. Thanks for the memories!

Brilliant! Just shows that the difference between a large team of engineers building the world's most powerful supercomputer and a hobbyist building it for fun is around 30 years (or less).

Great job, Chris, really impressive! So, from your description of the hardware architecture of the Cray-1 it seems modern CPUs haven't actually moved much in terms of architecture compared to their grand-dad :D

This is beyond awesome, Chris. I can't believe Xilinx didn't offer you some freebies and promote your project as a publicity stunt (maybe you should have tried Altera).

Shall we play a game? How about Global Thermonuclear War?

This is absolutely fantastic! Do you ever sleep? I don't know where you work, but I hope they allow you to use your obvious creativity and intelligence without a lot of restrictions.

I thought the name Chris Fenton sounded familiar...I ran across your DIY wooden laptop page a few years ago and bookmarked it. I thought that was awesome, but you've really outdone yourself this time!

Hi Ryan -- this really is impressive isn't it -- as I said before, I think Chris has a bright future ahead of him...

LATEST ARCHIVED BROADCAST
As data rates begin to move beyond 25 Gbps channels, new problems arise. Getting to 50 Gbps channels might not be possible with the traditional NRZ (2-level) signaling. PAM4 lets data rates double with only a small increase in channel bandwidth by sending two bits per symbol. But, it brings new measurement and analysis problems. Signal integrity sage Ransom Stephens will explain how PAM4 differs from NRZ and what to expect in design, measurement, and signal analysis.
