Science and applications

The FPGA testbed is funded by ExCALIBUR H&ES programme and intended to give HPC code developers access to a variety of FPGA technologies that they can use to experiment accelerating their codes. Some examples of successes:


If you are interested in using the FPGA testbed prototype for your research, please see https://fpga.epcc.ed.ac.uk/ for details of how to gain access.


The FPGA testbed system is managed by Adrian Jackson and Nick Brown at EPCC.
