ECMWF HPCFECMWF operates a Cray based High Performance Computing Facility (HPCF). It consists of two identical Cray XC40 clusters with their own storage, but with equal access to the high performance working storage of the other cluster. This provides the benefit of having one very large system but the dual clusters add significantly to the resiliency of the system. Each cluster has 20 cabinets of compute nodes and 13 cabinets of storage. The compute nodes contain two Intel Xeon "Broadwell" processors each with 18 cores. Four compute nodes sit on one blade, sixteen blades sit in a chassis and there are three chassis per frame. This gives a maximum of 192, or 6,912 processor cores per cabinet.
