Sometime ago I wrote about Adapteva, a company that ran a very successful Kickstarter campaign to create an affordable supercomputer (I think $99 for a machine capable of 26 GFLOPS qualifies as an affordable supercomputer). Oh, and it's open source!
Not only have they shipped the first batch of machines but they have also started taking orders through their Web site.
The final product spec is:
- Zynq-7020 dual-core ARM A9 CPU (runs Linux)
- Epiphany Multicore Accelerator (16 cores for $99 now; 64 cores, price to be announced)
- 1GB SDRAM
- MicroSD Card
- USB 2.0 (two)
- Four expansion connectors [option]
- Ethernet 10/100/1000
- HDMI connection
- Ships with free open source Epiphany development tools that include C compiler, multicore debugger, Eclipse IDE, OpenCL SDK/compiler, and run time libraries.
- Dimensions are 3.4” x 2.1”
What I think is really exciting is that you can cluster these boards ... like this:
The picture above shows:
... the first large scale Parallella cluster. The system consisted of 42 Parallella boards (for a total of 756 CPUs), with the total power consumption coming in under 500 Watts. This makes it possibly one of the densest clusters in the world thanks to the Parallella board!
So, 42 boards ... that's $4,185 for a performance of 1,092 GFLOPS at less than half a watt per GFLOP ... not bad for something that's desktop scale.
