Hardware Overview

The Noctua 2 FPGA infrastructure consists of 36 nodes in the fpga partition and 3 heterogeneous accelerator nodes in the hacc partition. Note that not only the dedicated hacc-nodes, but all nodes with AMD/Xilinx FPGAs are accessible as part of the Heterogeneous Accelerated Compute Clusters (HACC) program via a small project proposal for FPGA researchers worldwide.

A technical description of Noctua 2 and the FPGA partition can be found in the Noctua 2 paper.
