National Research Projects

Dapprox

Swiss National Science Foundation 2017–2022

Dependency-aware Approximate Analytics and Processing Platform

Dapprox is a set of methods and software tools for fast and approximate analyses of resource usage series in real time. The goal is to predict potential anomalies (and propose solutions) by simultaneously taking into account accuracy requirements, maximum delays and available resources.

WiBD

Swiss National Science Foundation 2018–2021

Women in Big Data

The mission of WiBD is to organize activities to promote women in Big Data research with a dual focus on social and technical sciences. W e advocate the importance of an open and broad discussion on building, advancing, and maintaining careers for women in Big Data fields.

LoadOpt

Swiss National Science Foundation 2013–2017

Workload Characterization and Optimization for Multicore Systems

Multicore architectures have become the standard, both for general-purpose PCs and for high-end servers. Such platforms provide an environment that is ideally suited for consolidating multiple applications within the same machine to take full advantage of the available parallelism.

GENiC

European FP7 ICT project 2013–2016

Globally Optimized Energy Efficient Data Centres

The GENiC platform provides a set of services that are loosely coupled on the GENiC controller cluster to support energy optimisation. These provide functionalities to handle data centre (DC) model mapping, sensor telemetry (airflow, temperature and power), workload actuation, fault detection and diagnosis and historical data storage.
