Faucet: An Open Source SDN Controller for High-Speed Production Networks

Open standards such as OpenFlow and P4 promised to improve the landscape by opening access to these devices via a programmable API, but they still require someone to write a controller to re-implement normal switch functionality, such as forwarding and routing, in a multi-vendor, standards-...

Assessing Progress in Automation Technologies

To assess the state of adoption of machine learning (ML) and AI, we recently conducted a survey that garnered more than 11,000 respondents. As I pointed out in previous posts, we learned many companies are still in the early stages of deploying machine learning: Companies cite “lack of data” and “...

What Is Machine Learning? We Drew You Another Flowchart

The vast majority of the AI advancements and applications you hear about refer to a category of algorithms known as machine learning. (For more background on AI, check out our first flowchart here.) Machine-learning algorithms use statistics to find patterns in massive* amounts of data. And data,...

Slurm Job Scheduling System

In previous articles, I examined some fundamental tools for HPC systems, including pdsh (parallel shells), Lmod environment modules, and shared storage with NFS and SSHFS. One remaining, virtually indispensable tool is a job scheduler. One of the most critical pieces of software on a shared cluster...

A Pioneering Scientist Explains Deep Learning

Buzzwords like “deep learning” and “neural networks” are everywhere, but so much of the popular understanding is misguided, says Terrence Sejnowski, a computational neuroscientist at the Salk Institute for Biological Studies. Sejnowski, a pioneer in the study of learning algorithms, is the author...
