IBM speeds deep learning by using multiple servers

For everyone frustrated by how long it takes to train deep learning models, IBM has some good news: It has unveiled a way to automatically split deep-learning training jobs across multiple physical servers — not just individual GPUs, but whole systems with their own separate sets of GPUs. Now the bad news: It’s available only in IBM’s PowerAI 4.0 software package, which runs exclusively on IBM’s own OpenPower hardware systems. [ Roundup: TensorFlow, Spark MLlib, Scikit-learn, MXNet, Microsoft Cognitive Toolkit, and Caffe machine learning and deep learning frameworks. | Cut to…

[Feature] Can deep reefs rescue shallow ones?

The colorful and diverse ecosystems of shallow coral reefs are threatened by pollution, overfishing, and global warming. Scientists wonder whether the little-studied, dimly lit deep coral reefs may serve as a lifeboat for shallow reefs under stress. Studies are just getting started to rigorously test this "deep reef refuge hypothesis," first proposed in 1996. A recent paper in Science Advances is one of the first, testing whether deep populations of corals might reseed shallow ones. Researchers suspect reseeding may happen in only a few coral species, but say the deep…

[Book Review] Deep exposures

Crystalline, a new exhibition showcasing the work of Irish artist Siobhán McDonald at the Centre Culturel Irlandais in Paris, France, brings together works created from relics of past scientific ventures to the frozen north and materials developed for an upcoming exploration of the Sun. The items are recomposed into artistic pieces that convey a melancholic contemplation of human striving and its consequences and the haunting histories that science both creates and records.
