[[Microsoft Catapult cluster ]]
The Microsoft Catapult system consists of 432 two-socket Intel Xeon-based nodes, each with 64 GB of memory and an Altera Stratix V D5 FPGA with 8 GB of local DDR3 memory. FPGAs communicate to their host CPUs via a PCIe Gen3 x8 connection, providing 8GB/s guaranteed-not-to-exceed bandwidth, and each FPGA can read and write data stored on its host node using this connection. The FPGAs are connected to one another via a dedicated network using high-speed serial links. This network forms a two dimensional 6x8 torus within a pod of 48 servers, and provides low latency communication between neighboring FPGAs. This design supports the use of multiple FPGAs to solve a single problem, while adding resilience to server and FPGA failures.
