Hewlett Packard Enterprise (HPE) said it acquired artificial intelligence startup Determined AI for an undisclosed amount.

Determined AI developed a software stack based on open source Horovod that it says trains AI models faster, at scale. It uses accelerator scheduling, fault tolerance, high-speed parallel and distributed training of models, advanced hyperparameter optimization and neural architecture search, reproducible collaboration, and metrics tracking.

In one case, Determined AI’s platform helped a company working on drug discovery speed up its training model time from three days to three hours, according to a case study.

The San Francisco-based startup, founded in 2017, has raised $13.6 million to date.

The company will join HPE’s High Performance Computing and Mission Critical Solutions business group, and on Wednesday, Determined AI CEO and co-founder Evan Sparks will join HPE’s Justin Hotard, who leads that business group, for an HPE Discover session: Unlocking Insight to Drive Innovation, From Edge to Exascale.

“Moving forward, we’ll be in a position to serve a much more global network of users, both large and small — we’re excited to continue building new features to both our customers and our open-source community,” wrote Sparks, along with co-founders Neil Conway and Ameet Talwalkar, in a blog post about the acquisition.

HPE has been building out its high-performance computing business over the past several years. In 2016, it bought big data analytics company SGI for $275 million. And in 2019 it paid $1.3 billion for supercomputer company Cray.

For its most recent earnings quarter, HPE’s high-performance compute revenue grew 13% to $685 million, up 13% from the prior-year period.
