The Parallella board was inspired by hardware communities such as Raspberry Pi, BeagleBoard and Arduino, and aims to democratise access to parallel computing by providing an affordable open high-performance computing (HPC) platform.
The platform is being built on the following principles:
- Open Access: all architecture and SDK documents openly published on the Web — no NDAs or special access required.
- Open Source: software platform based on free and open source software (F/OSS) development tools and libraries. Board design files provided under an open source hardware license once the Parallella computer ships.
- Affordable: the goal is to bring the hardware cost to below $100, making it an affordable platform for all.
The key features of the board are: a Xilinz Zynq SoC which provides a Dual ARM® Cortex™-A9 processor plus programmable logic, 16/64-core Epiphany floating-point accelerator (32/100 GFLOPS) and high bandwidth expansion via daughter cards.
The initial run of Parallella computers is being funded via a Kickstarter campaign, which on 27th October 2012 had succeeded in raising $898,921 via 4,965 backers, and with those pledging $99 or more receiving at least one board.
Thanks to generous support from Xilinx the Kickstarter boards will be upgraded to use a Zynq-7020 SoC instead of a Zynq-7010.
The first Parallella prototypes shipped in late December 2012 and comprise of a ZedBoard plus a 16 or 64-core Epiphany FMC.
From a software perspective the prototypes are virtually identical to the final form factor boards.
