Small Form Factor Data Center

OPERA will provide a datacenter in a box approach with a chassis are able to have up to 180 servers in a single 4.3U chassis.

Heterogeneous architecture

OPERA proposes to look at the problem of how to modify software to take advantage of a heterogeneous architecture with the focus on the constraint of power consumption.

New Generation Servers

In OPERA a new FPGA hardware that will be integrated in a scalable, heterogeneous, datacentre-in-a-box platform will be developed.

Ultra Low Power architecture

OPERA will investigate the definition of new HW/SW methodologies for specific computer vision application with a new approach based on convolutional neural networks.

High performance on ULP Architecture

The results in this area will provide a completely new type of device that will increase substantially the efficiency, with a new type of connections for data between sensor and processing unit.

Metrics for Energy efficiency

OPERA will conduct research to find the right energy efficiency metrics, derived from the researched model and translated in algorithms that are the best fit for the circumstances.

Workload decomposition on scalable Small Form factor DC

OPERA will develop an efficient workload decomposition system that automatically and dynamically executes tasks on the most suitable processing element.

Innovative Power Management

OPERA aim also to deliver a new management tools allowing for predictive workload and tightly integrated with server capabilities through standard interfaces.

ULP working prototype Real Time constraint

The objective of OPERA for this use case is to build a demonstrator of a traffic monitoring system composed by a very low power video traffic sensor and a datacentre-in-a-box that can be used in critical environments.
