D.A.V.I.D.E. was taken out of production on January 2020.

D.A.V.I.D.E. : (Development of an Added Value Infrastructure Designed in Europe) is an energy-aware Petaflops Class High Performance Cluster based on Power Architecture and coupled with NVIDIA Tesla Pascal GPUs with NVLink. The innovative design of D.A.V.I.D.E. has been developed by E4 Computer Engineering for PRACE, which has as its ultimate goal to produce a leading edge HPC cluster showing higher performance, reduced power consumption and ease of use. 

D.A.V.I.D.E. entered the TOP500 and GREEN500 list in June 2017 in its air-cooled version, while the current version features liquid cooling and an innovative technology for monitoring and capping the power consumption.

 D.A.V.I.D.E. is based on OpenPOWER platform and is among the harbingers of a new generation of HPC systems which deliver high performances while being environmentally conscious. It has been built using best-in-class components plus custom hardware and an innovative middleware system software.

A key feature of D.A.V.I.D.E. is an innovative technology for measuring, monitoring and capping the power consumption of the node and of the whole system, through the collection of data from the relevant components (processors, memory, GPUs, fans) to further improve energy efficiency. The technology has been developed in collaboration with the University of Bologna.
