Exploring alternate computer architectures

The FAbRIC (FPGA Research Infrastructure Cloud) project acquires and maintain comprehensive testbed systems and their tools for open use by all researchers wishing to explore the power of reconfigurable hardware. Reconfigurable hardware has tremendous potential in terms of performance and power efficiency. However, the high cost of such systems, the high cost of the tools needed to program such systems, and need to program at a very low level together put such systems out of reach of most researchers. The default usage model for Fabric is "open source to play", which enables anyone who agrees to let the team publish their open source code to use the facility free of charge. Such a shared platform with industrial-strength tools and open sourced code finally enables true reproducibility of research results and the ability to leverage others' work.

The original Fabric uses Convey FPGA platforms, and a new platform has just been added combining IBM's latest Power 8 processors with NVIDIA GPUs, and FPGAs from Altera and Xilinx, for researchers exploring alternate computer architectures. Supported by grants from IBM and NSF.
