旧金山4月15日电（路透社）——美国民主党参议员伊丽莎白·沃伦于周二致信美国能源部部长克里斯·赖特和国防部部长皮特·赫格斯瑟，就英伟达收购Slurm软件开发商SchedMD一事提出质询。
沃伦在给能源部和国防部部长的信中表达了对英伟达收购SchedMD的担忧，并要求“提供有关政府对英伟达硬件和软件的依赖程度的信息”。

英伟达于去年12月收购了Slurm软件开发商SchedMD。该软件为全球约60%的超级计算机提供支持。英伟达未披露交易规模。
SchedMD和Slurm并非家喻户晓的品牌。但此次收购延续了英伟达瞄准低调企业的模式——这些企业的技术是支撑全球最强大数据中心和超级计算机的关键纽带。
路透社看到的这封信中，沃伦要求提供有关美国能源部和国防部的计算机系统在多大程度上依赖英伟达硬件和软件产品的信息。沃伦还询问两部门是否评估了此次收购SchedMD带来的国家安全风险。
英伟达在一份声明中表示：“全球客户都能从我们的开源免费软件中获益。Slurm是开源软件，我们将继续为所有人提供升级更新。”
现已归属英伟达的SchedMD旗下Slurm软件负责调度计算任务，对美国政府超级计算机至关重要——这些系统可用于预测、运行弹道导弹模拟以及研发核武器。工程师还利用该软件构建大型人工智能模型，为Anthropic的Claude等聊天机器人提供支持。
Slurm在美国国防系统中的作用
沃伦在信中写道：“英伟达收购Slurm将使这款曾免费的软件转变为英伟达的专有产品，这可能会削弱竞争并损害国家安全。”“这将让英伟达过度掌控一个关键节点，竞争对手企业依赖该节点来运营政府超级计算机。”
本月早些时候路透社曾报道，五名使用这些超级计算机和人工智能系统的工程师和高管担心，英伟达会暗中偏袒自家产品。
也有一些用户希望，作为全球市值最高的上市公司，英伟达能够重振开源Slurm项目，投入其雄厚资源，为多年前为政府超级计算机开发的系统推出期待已久的更新。
沃伦的信将路透社的这篇报道列为信息来源之一。
英伟达交易面临的反垄断审查
沃伦在信中讨论了英伟达收购其他软件公司的交易，并以Bright Computing和Run:ai为例，称这两家公司此前都曾面临反垄断审查。
英伟达于2022年收购Bright Computing，2024年收购Run:ai。两家公司均开发用于运行超级计算机和AI芯片集群关键计算基础设施的软件。
沃伦表示：“除了扩大AI芯片供应，这些交易还让英伟达进一步掌控了运行数据中心和超级计算系统所需的关键软件及支持服务。”
“如果英伟达同时掌控AI芯片和让这些芯片运转的软件层，他们就能够通过提高竞争对手部署硬件和获得支持的难度，将竞争者挤出市场。”

- Senator Warren questions US Energy and Defense departments on Nvidia’s SchedMD acquisition impact
- Letter raises concerns over Nvidia’s control of Slurm software vital for government supercomputers
- Warren cites prior Nvidia deals facing antitrust scrutiny, warns of reduced competition
SAN FRANCISCO, April 15 (Reuters) – U.S. Democratic Senator Elizabeth Warren sent a letter to the U.S. secretaries of the Department of Energy and Department of Defense on Tuesday, questioning them about Nvidia’s acquisition of SchedMD, which makes Slurm software.
Warren’s letter to Energy Department Secretary Chris Wright and Defense Department Secretary Pete Hegseth expressed worries about Nvidia’s acquisition of SchedMD and requested “information about the government’s dependency on NVIDIA hardware and software.”

Nvidia bought the Slurm software developer SchedMD in December. The software helps power about 60% of supercomputers worldwide. Nvidia did not disclose the size of the transaction.
SchedMD and Slurm are not household names. But the deal follows a pattern of Nvidia targeting under-the-radar companies whose technology serves as the glue holding the world’s most powerful data centers and supercomputers together.
In the letter, which was seen by Reuters, Warren asked for information about the extent to which computer systems in the U.S. departments of Energy and Defense are dependent on Nvidia’s hardware and software products. Warren asked whether either department has assessed national security risks related to the SchedMD acquisition.
“Customers everywhere benefit from our open source and free software,” Nvidia said in a statement. “Slurm is open-source and we continue to provide enhancements for everyone.”
The SchedMD – now Nvidia – Slurm software schedules computing tasks and is crucial for U.S. government supercomputers, which help forecast and run ballistic missile simulations and develop nuclear weapons. Engineers also use it to build the large artificial intelligence models that power chatbots such as Anthropic’s Claude.
SLURM’S ROLE IN U.S. DEFENSE SYSTEMS
“NVIDIA’s acquisition of Slurm turns a once free software into one of NVIDIA’s proprietary offerings, which may reduce competition and harm national security,” Warren wrote. “This would give NVIDIA disproportionate control over a chokepoint that rival firms rely on to operate government supercomputers.”
Some of the engineers and executives who use those supercomputer and AI systems fear that Nvidia will subtly favor itself, five people said, Reuters reported earlier this month.
There also is a hope among some users that Nvidia, the world’s most valuable publicly traded company, will reinvigorate the open-source Slurm, pouring some of its staggering resources into long-awaited updates of a system built years ago for government supercomputers.
Warren’s letter mentioned the Reuters story as a source.
ANTITRUST SCRUTINY OF NVIDIA DEALS
Warren’s letter discussed Nvidia’s acquisitions of other software companies and cited Bright Computing and Run:ai as examples, which it said have faced antitrust scrutiny.
Nvidia bought Bright Computing in 2022 and Run:ai in 2024. Both companies make software that helps run the computing infrastructure critical for supercomputers and clusters of AI chips.
“In addition to expanded supply of AI chips, these deals have given NVIDIA even more control over the critical software and the support that helps run data centers and supercomputing systems,” Warren said.
“If NVIDIA controls both AI chips and the software layers that make these chips work, they are in a position to box out competitors by making their hardware harder to deploy and harder to support.”
