helmholtz-analytics/heat: Heat 1.0: Data Parallel Neural Networks, and more

Release Notes Heat v1.0 comes with some major updates: new module nn for data-parallel neural networks Distributed Asynchronous and Selective Optimization (DASO) to accelerate network training on multi-GPU architectures support for complex numbers major documentation overhaul support channel on StackOverflow support PyTorch 1.8 stop supporting Python 3.6 many more updates and bug fixes, check out the CHANGELO

helmholtz-analytics/heat: Heat 1.1.0: distributed slicing/indexing overhaul, dealing with load imbalance, and more

Highlights Slicing/indexing overhaul for a more NumPy-like user experience. Special thanks to Ben Bourgart @ben-bou and the TerrSysMP group for this one. Warning for distributed arrays: breaking change! Indexing one element along the distribution axis now implies the indexed element is communicated to all processes. More flexibility in handling non-load-balanced distributed arrays. More distributed operations, incl. meshgrid . For other details, see the CHANGELOG

Key technologies to accelerate the ICT Green evolution An operator's point of view

The exponential growth in networks' traffic accompanied by the multiplication of new services like those promised by the 5G led to a huge increase in the infrastructures' energy consumption. All over the world, many telecom operators are facing the problem of energy consumption and Green networking since many years and they all convey today that it turned from sustainable development initiative to an OPEX issue. Therefore, the challenge to make the ICT sector more energy-efficient and environment-friendly has become a fundamental objective not only to green networks but also in the domain of green services that enable the ICT sectors to help other industrial sector to clean their own energy consumption. The present paper is a point of view of a European telecom operator regarding green networking. We address some technological advancements that would enable to accelerate this ICT green evolution after more than 15 years of field experience and international collaborative research projects. Basically, the paper is a global survey of the evolution of the ICT industry in green networks including optical and wireless networks and from hardware improvement to the software era as well as the green orchestration
