Due to our diverse lab equipment, we are running various setups of solvers. Each single FPGA device hosts several solver instances, which we call slices. Some of the FPGA setups are represented by only a single available board.

Slice Equivalent measured in the number of 100 MHz Slices of the same computational power.

The clock frequencies might appear forbiddingly low as compared to the multi-gigahertz general purpose CPUs. The power of our designated design is the avoidance of any instruction set overhead and the tremendous concurrency even on a single chip.

As we can only utilize the idle time of these of our lab resources, we are constantly searching for sponsors of high-performance FPGAs.
