What is Enzian?
Enzian is a powerful computer for doing systems software research. You can use a single Enzian on its own, or connect a rack of them together.
Enzian is a cache-coherent 2-node asymmetric NUMA system where one node is a 48-core CPU and one node is an FPGA. It has a maximum of 640GiB of DDR4 RAM, and has up 480Gb/s of network bandwidth, both split between the two nodes. The board looks like this:
