Over the past several years, Facebook has developed software that can read stories, answer questions, play games, and even learn things. Now, the company is taking its artificial intelligence efforts to the next level: hardware.

The social network on Thursday unveiled new AI hardware its researchers have developed to train neural networks, and open-sourced the design, offering other organizations a blueprint for how to set up their own AI-specific infrastructure. Designed in collaboration with Nvidia, the Open Rack-compatible hardware is designed for AI computing at a large scale.

Dubbed "Big Sur," the hardware includes eight high-performance GPU boards of up to 33 watts each. Compared to Facebook's previous system, "we can train twice as fast and explore networks twice as large," Facebook's Kevin Lee and Serkan Piantino wrote in a blog post.

"Distributing training across eight GPUs allows us to scale the size and speed of our networks by another factor of two," they added.

It's also "far more versatile and efficient" than the off-the-shelf solutions Facebook was using in the past. Many high-performance computing systems require special cooling to operate, but Facebook has designed its new servers for "thermal power and efficiency," allowing the company to operate them in its own free-air cooled, Open Compute standard data centers. Facebook also ditched components that don't get used very much and made it so that components that fail often — like hard drives — can be removed and replaced within "seconds."

"We want to make it a lot easier for AI researchers to share techniques and technologies," Lee and Piantino wrote. "As with all hardware systems that are released into the open, it's our hope that others will be able to work with us to improve it."

Meanwhile, Facebook also on Thursday said its AI Research team is more than tripling its investment in GPU hardware, and enabling other teams across the company to use neural network in their products and services.

My Experience

I'm PCMag's managing editor for consumer electronics, overseeing an experienced team of analysts covering smart home, home entertainment, wearables, fitness and health tech, and various other product categories. I have been with PCMag for more than 10 years, and in that time have written more than 6,000 articles and reviews for the site. I previously served as an analyst focused on smart home and wearable devices, and before that I was a reporter covering consumer tech news. I'm also a yoga instructor, and have been actively teaching group and private classes for nearly a decade. 

Prior to joining PCMag, I was a reporter for SC Magazine, focusing on hackers and computer security. I earned a BS in journalism from West Virginia University, and started my career writing for newspapers in New Jersey, Pennsylvania, and West Virginia.

The Technology I Use

My little Florida beach bungalow is brimming with smart home tech. I have a smart speaker or display in every room, allowing me to control other connected devices by voice. The Nest Hub on my bedside table lets me set wake-up alarms, control my smart light bulbs, and set the temperature on my smart thermostat. I use the Amazon Echo Show 8 on my kitchen counter to browse recipes, reorder protein powder, check the weather, and watch the news while I do dishes. 

Because I suffer from allergies, air purifiers are essential. My favorite model is the Dyson Purifier Cool TP07, which doubles as a fan and continuously sends indoor pollution data to its companion mobile app. 

My pitbull Bradley sheds, so a good robot vacuum is a must. I currently use a premium Ecovacs Deebot that can both vacuum and mop, empty its own dustbin, and wash its own mop cloth. 

For fitness, I like to mix up my routine with cycling, indoor rowing, running, and strength training in addition to yoga. I take classes on the Tonal 2 smart strength training machine, I row indoors on an Aviron machine, and track my beach runs with an Apple Watch while listening to music on my Apple AirPods Pro. On the weekends, I love riding e-bikes like the rugged, beach-friendly Aventon Aventure for fun and fitness.

My job involves a lot of virtual meetings, so a quality webcam, microphone, and ring light are important. I use the Jabra PanaCast 20 webcam, the Elgato Wave: 3 microphone, and a Yesker tripod ring light. 

As for my preferred phone platform, I'm an iPhone person, but I've also extensively used Android for product testing.
