mlloyd - A few years back we decided to stay away from the high speed SERDES and use a source synchronous LVDS interface instead. This way we could attach to low cost as well as high end FPGAs.  The interface does use a fair amount of pins (8 data lanes) but can provide up to 16Gb/s total bandwidth with a 500MHz clock. This turned out to be a good choice because the low cost zynq 7010 and 7020 don't currently support high speed serdes.

@Adapteve: Once we put together a cluster of 1,000 of these Parallella boards...

Once you do, I want to see pictures!!!

Congratulations, Andreas, on shipping your product and nearing your large milestones.  I am curious about your eLink interface between the Zynq and Epiphany.  Since you designed the Epiphany from scratch, is it able to make use of the high-speed transceivers offered by the Zynq?  We commonly interface processors to FPGAs in my business, and it is always a challenge to find processors that have high-speed buses that we can use to communicate with our FPGAs.

The Parallella actually has a ~10Gb/s memory mapped low-latency link (through the "PEC" connector) that can be used to to construct some interesting large scale topologies. See the specs here.http://www.parallella.org/board

Does anyone know why they didn't include some type of high speed message passing bus?

The supercomputing capability of such a scalable setup seems limited to the latency/throughput of the ethernet bus.

Rick- Thanks! Once we put together a cluster of 1,000 of these Parallella boards we will definitely be getting up into real "supercomputer" territory, although the definition is a moving target.

Congrats, Andreas. It will be interesting to see what people do with these boards--perhpas will will get a mini-Top 500.

Dylan- Thanks! Shipping 6,300 boards is the one that really matters to us. The expectations of 5,000 KS backers has been a big weight to carry for 9 months now. Fortunately for us they have been incredibly patient and understanding. We'll definitely keep you posted. If you don't hear from us something i wrong:-)

Thanks! We did reach profitability briefly but were not able to sustain the momentum. As you know, profitability is not a stable state:-)
