Reduceron has been implemented on various FPGAs with clock frequency ranging from 60 to 150 MHz depending on the FPGA. A high degree of parallelism allows Reduceron to implement graph evaluation very efficiently. This fork aims to continue development on this, with a view to practical applications. Comments, questions, etc are welcome.
