Today’s data centres have an efficiency problem – much of their energy is used not to process data, but to keep the servers cool. A new server architecture under development by the EU-funded COMPUSAPIEN project could solve this. As the digital revolution continues to accelerate, so too does our demand […]

The Cloud Sustainability Days, organised by the EPFL EcoCloud Center, are beginning. LINK TO LIVE COVERAGE PROGRAM Please use the basement entrance: This conference is organised by the EPFL EcoCloud Center for sustainable cloud technologies, with the participation of the Swiss Datacenter Efficiency Association, the EPFL FUSTIC association, members of […]

Researchers at Ecocloud, the EPFL Center for Sustainable Cloud Computing, have pioneered an innovative approach to implementing virtual memory in data centers, which will greatly increase server efficiency. Virtual Memory has always been a pillar for memory isolation, protection and security in digital platforms. The use of virtual memory is […]

DNN training and inference have similar basic operators but with fundamentally different requirements. The former is throughput bound and relies on high precision floating-point arithmetic for convergence while the latter is latency-bound and tolerant to low-precision arithmetic. Both workloads require high computational capabilities and can benefit from hardware accelerators. The disparity in resource requirements forces datacenter operators to choose between custom accelerators for training and inference or training accelerators for inference.

In their paper, the researchers introduce a nanowire-based device to create high-electron-mobility tri-gate transistors for power-conversion applications. Based on nanoscale structures, the novel transistor design significantly reduces heat loss during the energy conversion process.

Contrary to expectations, the experiment revealed that the respondents held on to their views firmly, regardless of the celebrity inputs or their esteem in the eyes of the respondents. It was also clear that respondents liked to hear an opinion identical to their own even if it came from a disliked celebrity. Conversely, a dissenting opinion by a celebrity or expert reduced the respondent’s empathy for that person.

Two EPFL students have developed PowerSGD, an algorithm that allows compression of the needed bandwidth without compromising the accuracy of the training.

CrowdNotifier, a new protocol developed in part at EPFL. It alerts people who attended an event where there was a risk of COVID-19 infection.

Researchers from EPFL and INRIA have developed the first online FL system called FLeet, which makes it possible to carry out machine learning on mobile devices in real-time without any impact on learning tasks.
