Cray XC40 Ventus at ECMWF
One of two identical Cray XC40 clusters in ECMWF’s high-performance computing facility (HPCF).
Each cluster had 20 cabinets of compute nodes and 13 of storage and weighed more than 50 metric tonnes. The bulk of the system consisted of compute nodes with two Intel Xeon E5-2695 V4 “Broadwell” processors each with 18 cores.
•~3,600 nodes/130,000 compute cores per cluster
•Combined performance of the two clusters: ~8.5 petaflops peak and ~320 teraflops sustained performance
•Numbers 23 and 24 in the November 2016 Top 500 Supercomputers list
