OpenAI releases Triton, a programming language for AI workload optimization

All the sessions from Transform 2021 are available on-demand now. Watch now.


OpenAI today released Triton, an open source, Python-like programming language that enables researchers to write highly efficient GPU code for AI workloads. Triton makes it possible to reach peak hardware performance with relatively little effort, OpenAI claims, producing code on par with what an expert could achieve in as few as 25 lines.

Deep neural networks have emerged as an important type of AI model, capable of achieving state-of-the-art performance across natural language processing, computer vision, and other domains. The strength of these models lies in their hierarchical structure, which generates a large amount of highly parallelizable work well-suited for multicore hardware like GPUs. Frameworks for general-purpose GPU computing such as CUDA and OpenCL have made the development of high-performance programs easier in recent years. Yet, GPUs remain especially challenging to optimize, in part because their architectures rapidly evolve.

Domain-specific languages and compilers have emerged to address the problem, but these systems tend to be less flexible and slower than the best handwritten compute kernels available in libraries like cuBLAS, cuDNN or TensorRT. Reasoning about all these factors can be challenging even for seasoned programmers. The purpose of Triton, then, is to automate these optimizations, so that developers can focus on the high-level logic of their code.

“Novel research ideas in the field of deep learning are generally implemented using a combination of native framework operators … [W]riting specialized GPU kernels [can improve performance,] but [is often] surprisingly difficult due to the many intricacies of GPU programming. And although a variety of systems have recently emerged to make this process easier, we have found them to be either too verbose, lack flexibility, generate code noticeably slower than our hand-tuned baselines,” Philippe Tillet, Triton’s original creator, who now works at OpenAI as a member of the technical staff, wrote in a blog post. “Our researchers have already used [Triton] to produce kernels that are up to 2 times more efficient than equivalent Torch implementations, and we’re excited to work with the community to make GPU programming more accessible to everyone.”

Simplifying code

According to OpenAI, Triton — which has its origins in a 2019 paper submitted to the International Workshop on Machine Learning and Programming Languages — simplifies the development of specialized kernels that can be much faster than those in general-purpose libraries. Its compiler simiplifies code and automatically optimizes and parallelizes it, converting it into code for execution on recent Nvidia GPUs. (CPUs and AMD GPUs and platforms other than Linux aren’t currently supported.)

“The main challenge posed by our proposed paradigm is that of work scheduling — i.e., how the work done by each program instance should be partitioned for efficient execution on modern GPUs,” Tillet explains in Triton’s documentation website. “To address this issue, the Triton compiler makes heavy use of block-level data-flow analysis, a technique for scheduling iteration blocks statically based on the control- and data-flow structure of the target program. The resulting system actually works surprisingly well: our compiler manages to apply a broad range of interesting optimization automatically.”

The first stable version of Triton, along with tutorials, is available from the project’s GitHub repository.

In addition to its new gaming desktops and monitors, Acer has introduced its latest gaming laptop and accessories lineup, including the Predator Helios 500 and Predator Triton 500 SE models. In addition to the laptops, the company has launched the Predator Connect X5 5G CPE router, the Predator Connect D5 5G dongle, and the Predator Cestus Gaming Mouse 335.

Acer Predator Helios

Joining the new Triton model is the Predator Helios 500 gaming laptop, a model featuring the 11th-generation Intel Core i9 processor, the NVIDIA GeForce RTX 3080 laptop GPU, as well as 64GB of RAM. The laptop features a 17.3-inch display with different panel options, including the 4K Mini LED 120Hz option or the Superfast Full HD 360Hz display with a 3ms response time.

Acer has packed a bunch of features into this model, including support for two PCIe NVMe SSDs in Raid 0 plus one SATA hard drive for ample storage space. As you’d expect from a gaming laptop, there’s also a robust thermal system that includes Acer PowerGem and Vortex Flow with two fans.

As the images show, the Helios also sports Predator Pulsar lighting with customizable light bars. The keyboard’s RGB backlighting can be customized, plus the WASD keys can be swapped with MagForce or Racing keys. Connectivity is extensive with things like Intel Killer Ethernet, including DoubleShot Pro 5G, plus there’s WiFi 6, DTS:X Ultra audio, and simulated 3D surround sound.

The Predator Helios 500 will be available in North America in August with a starting price of $2,499.99 USD.

Acer Predator Triton

The new Predator Triton 500 Special Edition (“SE”) is a gaming laptop capable of powering AAA games. The model packs the 11th-generation Intel Core i9 processor, as well as the NVIDIA GeForce RTX 3080 laptop GPU, up to 64GB of RAM, and up to 12 hours of battery depending on usage. Users can get the laptop with up to 4TB of internal storage.

Despite this, the laptop remains slim for a gaming machine at 0.75-inches. The Predator Triton packs a 16-inch display with an 87-percent screen-to-body ratio. Users can choose from three different panel options, including two with a 165Hz refresh rate and one with a 240Hz refresh rate.

Other features include WiFi 6, Intel Killer E3100G Ethernet controller, two Thunderbolt 4 ports, Acer’s Vortex Flow cooling design with AeroBlade 3D Fan, and an SD 7.0 card reader. The Predator Triton 500 SE will be available in North America next month with a starting price of $1,749 USD.

Acer Predator Triton 500 Review: This thin and light laptop even has GeForce RTX

Acer’s Predator Triton 500 is a gaming laptop we’d actually want to carry around. Sure, we may look hungrily at a monster gaming laptop that’s nearly as fast as a desktop gaming PC. But if you have to take it with you, the era of thin, light and powerful gaming laptops is a godsend.

This review is part of our ongoing roundup of the best gaming laptops. Go there for information on competing laptops and how we tested them, and up-to-date buying advice. 

Acer Predator Triton 500 Core i7-8750H GeForce RTX 2060 Adam Patrick Murray

The Acer Predator Triton 500 features an 8th gen Core i7-8750H and Nvidia GeForce RTX 2060 GPU, along with 16GB of dual-channel RAM and a 512GB NVMe M.2 SSD.

Acer Predator Triton 500 Specs and Features

The Predator Triton 500 is one of the first gaming laptops we’ve tested with Nvidia’s RTX mobile chip. Even though its CPU is “merely” 8th-gen when 9th-gen CPUs have recently become available, that GPU matters a lot more when it comes to gaming. Here are the details: 

  • CPU: Intel 8th-gen Core i7-8750H
  • Memory: 16GB DDR4/2666 in dual-channel mode
  • GPU: Nvidia GeForce RTX 2060
  • Display: 15.6-inch, 144Hz, 1920×1080 screen
  • Storage: 512GB NVMe SSD
  • Dimensions: 14 x 10 x 0.75 inches (without the feet)
  • Weight: 4.75 pounds, 5.9 pounds with AC adapter 

The Predator Triton 500’s size and weight put it in the thin-and-light gaming category. Granted, it’s almost 12 ounces ounces heavier than, say, the original MSI GS65 Stealth we reviewed. However, MSI has since beefed up the original with newer components, and the latest version (which we’re still reviewing) weighs about 4.4 pounds.

The display is the standard-issue 15.6-inch, 1920×1080 resolution, 144Hz “IPS” panel seen in most thin and light gaming laptops. To aid in battery life, Acer also decided to skip G-sync, which means the GPU doesn’t have to be on at all times. G-sync is a proven drag on battery life in other laptops we’ve tested. 

Ports

The Predator Triton 500’s port selection is good. The right side features two USB-A ports, a miniDisplayPort, and a Thunderbolt 3 port. The miniDisplayPort is plumbed directly to the GeForce RTX 2060, so even though the Predator Triton 500’s panel doesn’t support G-sync, you can run an external G-sync panel.

You get two USB-A ports, a miniDisplayPort and Thunderbolt 3 on the right side of the Predator Triton 500.

The right side of the Predator gives you a full-size HDMI port, analog mic and headset jack, a third USB-A port, a dedicated charging port, plus ethernet with support for 2.5 Gigabit using a Killer E3000 controller.

The back of the Predator Triton 500 is heavily vented and features beautiful anodized-blue cooling fins.

Keyboard and trackpad

The Triton 500’s keyboard makes no major gaffes, and we like that Acer went with full-size cursor keys rather than the compressed keys you find on some laptops. The trackpad is fairly smooth, although with a slight drag to its surface. To its credit, however, it’s correctly sized and properly centered on the Y key. We’ve sometimes seen trackpads shifted an inch to the right, which caries the risk of placing more of your palm on the trackpad.

Save a legit $700 on Acer’s ultra-powerful Predator Triton 500 laptop

We don’t cover high-priced laptop deals that often. Today’s deal is so good, however, that we can’t help but point it out. Amazon is selling an Acer Predator Triton 500 with a GeForce RTX 2080 Max-Q for $1,800, a firm $700 off its usual $2,500 sticker price. This laptop was down around $2,000 briefly in late January, but it’s usually selling for the higher price on Amazon.

We adored the Acer Predator Triton 500 when we reviewed it in May, awarding it a firm 4 stars, albeit with a different internal configuration. It combines fierce gaming power with a light and thin chassis, making it ideal for carting around town.

And this thing is loaded.

The version of the Acer Predator Triton 500 on sale today packs the six core, twelve thread 2.2Ghz “Coffee Lake” Core i7-8750H—one of Intel’s most potent gaming processors—paired with Nvidia’s high-end GeForce RTX 2080 Max-Q. “Max-Q” means it has slightly less performance than a typical RTX 2080, since the clock speeds are lowered in order to improve the laptop’s power efficiency. Don’t worry about performance, however, as this graphics card will still be a beast for the Triton’s killer display setup.

Speaking of which, the display is a 15.6-inch 1080p G-Sync panel with a 3ms response time and a 144Hz refresh rate. Nvidia’s G-Sync panel technology synchronizes the refresh rate of your GPU and monitor for a buttery-smooth gaming experience free from stutter or screen-tearing. The laptop also comes with 16GB of RAM and a speedy 512GB NVMe SSD.

Add that all up, and you get an absolute beast of a gaming laptop in a package that weighs less than 5 pounds. And today, the Acer Predator Triton 500 is ready to blow you away for a whopping $700 off.

Acer’s Predator Triton 500 gets a 300Hz panel and beastly internal upgrades

Intel and Nvidia blitzed the technology world with the simultaneously launch of 10th-gen Core CPUs and GeForce RTX Super GPUs on Thursday, and now Acer’s Predator Triton 500 gaming laptop is adding to the shock and awe.

The Predator Triton 500 has long been coveted for its fairly light weight and thin body. The newest iteration takes it to the next level with Intel’s latest 10th-gen Comet Lake H chips. The 14nm Comet Lake H CPUs bump some Core i7 chips up to 8-cores, and bumps up the boost clock on the Core i9.

What’s inside of the Predator Triton 500 wasn’t made clear though—does the Triton 500 feature an 8-core chip or 6-core chip like its predecessor? We hope it moved up the chain, as the Triton 500’s nemesis—MSI’s GS66 Stealth—will offer an 8-core chip in a similar 4.6-pound frame.

Acer’s Predator Triton 500 gets upgraded with a 10th gen Intel Comet Lake H, GeForce Super chips and Killer 2.5GbE plus a 300Hz panel.

The previous Triton 500 offered up to a GeForce RTX 2080 Max-Q so the GeForce RTX 2080 Super Max-Q in the latest Acer may not impress at first glance. But the Super-series packs more CUDA cores than their vanilla counterparts, and Nvidia made some key advancements in this new generation of Max-Q tech to improve both performance and power efficiency, so the new model could be a good step faster.

The 15.6 screen in the Triton 500 also gets a nice buff courtesy of a 300Hz IPS screen, Acer said. That screen, interestingly, supports Nvidia’s G-Sync, but it’s not clear if it supports Nvidia’s new Advanced Optimus feature that lets you switch from G-Sync (which consumes more power since the GPU is on all of the time) to the integrated graphics chip. Advanced Optimus was introduced as part of the Max-Q enhancements in this new breed of GeForce GPUs, but it’s an optional feature for laptop makers.

Killer’s E3100 controller will be used in Acer and MSI laptops and offer 2.5GbE to consumers.

A nice touch for people into high-speed networks is the inclusion of Killer’s E3100G ethernet chip, which supports 2.5GbE. Plain old wireless people will also get Wi-Fi 6 using a Killer AX1650i controller.

Acer said the laptop will be offered with up to 32GB of DDR4 and also up to 2TB of space using NMVe RAID 0. That pretty much tells us there’s space for two drives inside.

For those who want something a little more down to earth, Acer is also offering the Nitro 5 with Intel’s newest 10th-gen Comet Lake CPUs. Decidedly more affordable, the Nitro 5 will offer options up to a GeForce RTX 2060 as well as a more wallet friendly GeForce GTX 1650 Ti GPU. Even though it’s friendlier to your credit card, the Nitro 5 will still pack up to two M.2 SSDs, plus a 2.5-inch drive. RAM tops out at 32GB in standard SO-DIMM slots and the 15.6 FHD IPS screen will be offered with both 144Hz and 120Hz options.

Acer Predator Triton 500 (2020) review: A truly portable powerhouse

I’ve tested a lot of gaming laptops over the years, but the newly refreshed Acer Predator Triton 500 is the best one I’ve ever had the pleasure of playing on.

For many years, you could only coax enthusiast-class performance out of mammoth gaming laptops that threatened to throw out your back while you carried them around in your bag. The introduction of Nvidia’s energy-efficient Max-Q technology resulted in more portable play-worthy notebooks, but the truly totable ones usually topped out with graphics options below the upper echelon of performance. Gaming on the go always required some sort of compromise.

No more. The Acer Predator Triton 500 brings it all, pairing a 6-core, 12-thread Intel Core i7-10750H processor with Nvidia’s potent new GeForce RTX 2080 Super graphics chip. All that power somehow squeezes into a sublime 4.6-pound aluminum chassis with a lightning-fast 300Hz G-Sync display that offers drop-dead gorgeous contrast ratios. Is it perfect? Not quite. But hot damn, I love it.

Acer Predator Triton 500 specs and features

acer predator triton 500 2020 9 Brad Chacos/IDG

Acer sent us the highest-end Triton 500 on offer, loaded with every feature you could ask for. Acer’s site ostensibly lists it for $2,600, but at press time we could only find it available for $2,800 at B&H Photo. You get a lot of hardware for all those pennies.

  • CPU: Intel 10th-gen Core i7-10750H
  • Memory: 32GB DDR4/3200 in dual-channel mode
  • GPU: Nvidia GeForce RTX 2080 Super Max-Q
  • Display: 15.6-inch, 300Hz, 1920×1080 IPS screen with Nvidia G-Sync
  • Storage: 1TB Samsung NVMe SSD
  • Dimensions: 14.1 x 10 x 0.75 inches (without the feet)
  • Weight: 4.6 pounds 

There’s not much more you could ask for. The included Samsung NVMe SSD blazes along, but if you want even faster speeds, there’s another M.2 slot for expansion, and Acer loaded the laptop with Intel software ready to get a dual-SSD setup humming in RAID 0.

The storage and RAM are difficult to access, however. The Triton 500 uses an inverted motherboard design, which means you’ll need to yank out ribbon cables and the entire motherboard to access the expansion slots. Fortunately, the stock configuration comes with plenty of firepower.

Even the Internet is fast on this beast. The Acer Predator Triton 500 includes Killer’s AX1650 Wi-Fi 6 module and Killer DoubleShot Pro technology. DoubleShot Pro lets the gaming-optimized 2.5 Gigabit ethernet port work together with the notebook’s 802.11ac Wi-Fi, shifting more important tasks to the wired connection and less urgent tasks to the wireless network. The Triton 500 also supports Bluetooth 5.

Left-edge ports.

Acer included an ample port selection despite this gaming laptop’s relatively small size. The Triton 500 comes with a trio of USB 3.0 ports, Thunderbolt 3, HDMI 2.0, Mini DisplayPort, headset and mic jacks, and the aforementioned ethernet port. It also includes a Kensington lock slot for more security-conscious types.
