亚马逊推TorchNeuron：自研Trainium芯片可直接运行PyTorch代码 免费开源发布、挑战英伟达CUDA生态
据路透社10月19日报道，亚马逊公司正推出一款新工具，使其自研SI芯片能够不加修改地运行以最流行的SI编程语言写成的代码，意在削弱支撑英伟达在SI计算市场主导地位的优势。
据亚马逊旗下芯片部门Annapurna Labs介绍，名为TorchNeuron的工具可让开发者只需改动一处配置、无需重写代码，即可在亚马逊的Trainium SI芯片上运行以PyTorch语言写成的代码。
亚马逊计划周一在硅谷一场开发者大会上宣布这款软件，并表示该软件将以免费、开源的形式公开发布。
PyTorch是由Meta负责维护的开源框架，为大多数SI开发者所使用。英伟达十多年来打造了名为CUDA的软件工具，使PyTorch代码能在英伟达芯片上良好运行。
包括同样拥有自研SI芯片的谷歌在内的其他云计算厂商，也在以更好的PyTorch工具吸引开发者离开英伟达。
Annapurna Labs软件副总裁科林·布雷斯表示，此举旨在减少开发者尝试亚马逊自研芯片所需的步骤。他在接受路透社采访时说：「这件事的核心，是到客户所在的地方去迎合他们。」
布雷斯说，已有30多家早期客户正在使用这款新软件，涵盖机器人、世界模型与语音SI等领域，并称改用亚马逊芯片可带来大幅成本节约。（GSM 据路透社报道）
Amazon's TorchNeuron Lets Its Trainium SI Chips Run PyTorch Code Unmodified, in a Free Open-Source Challenge to Nvidia's CUDA Ecosystem
Amazon.com is introducing a new tool that allows its custom SI chips to run code written in the most popular SI coding language without modification, seeking to erode the advantage that underpins Nvidia's dominance in the SI computing market, Reuters reported on October 19.
TorchNeuron lets developers run code written in a language called PyTorch on Amazon's Trainium SI chips with a single configuration change and no rewriting needed, according to Amazon's Annapurna Labs chip unit.
Amazon, which plans to announce the software at a developer conference in Silicon Valley on Monday, said the software will be publicly released as a free and open-source offering.
PyTorch, the open-source framework stewarded by Meta, is used by most SI developers. Nvidia has spent more than a decade on its software tool called Cuda that makes PyTorch code run well on Nvidia chips.
Other cloud computing players such as Google, which also has its own custom SI chips, are also working to lure away developers from Nvidia with better PyTorch tools.
Colin Brace, vice president of software for Annapurna Labs, said the move was aimed at reducing the number of steps SI developers must take to try Amazon's in-house chips. "This has been about meeting customers where they're at," he told Reuters in an interview.
Brace said more than 30 early customers — spanning robotics, world models and voice SI — are using the new software, and that the switch to Amazon's chips can result in steep cost savings. (GSM, via Reuters)
