Limestone Networks and Charg Unleash 60-PFlop Supercomputer for the AI Era

DALLAS, Sept. 26, 2025 /PRNewswire/ -- Limestone Networks, the global bare-metal and cloud infrastructure powerhouse, has teamed up with Charg to light up a 60-petaflop supercomputer, purpose-built for AI and next-gen enterprise workloads.

This isn't another hyperscaler project, it's a play to make supercomputing power accessible on demand for researchers, startups, and enterprises racing to train and deploy large-scale AI models.

Charg tapped Limestone to design, build, and run the colocation and global network backbone that fuels the system. Now Limestone is spearheading the GTM push, bringing one of the world's most powerful GPU clouds directly to market.

"Timing is everything. The time is now. Limestone Networks and Charg is delivering one of the largest GPU clusters at scale." said Preston Gosdin, CEO of Limestone Networks. "Charg brought the GPUs, we brought the global backbone, and together we built a monster. Enterprises, startups, researchers: if you're ready to push AI past the limit, #LSNMetal-Supercharg'd is open for business."

Under the hood, the system features 200 Gbps HDR InfiniBand fabric, an all-flash storage layer, and upcycled Cray supercomputing chassis engineered for scalability.

At 60 petaflops of raw performance, the deployment ranks among the largest GPU-driven platforms commercially available—capable of accelerating everything from deep learning research to enterprise-scale inference pipelines.

Judd Lindvall, Chief Cloud Officer at Charg  added: "Limestone's ability to execute complex builds at scale made them the obvious choice. Together, we're not just building a cloud, we're redefining high-performance computing."

The system goes live in early October, with pre-sales now open at LimestoneNetworks.com. Enterprises, startups, and researchers can lock in early access to supercomputing performance without the hyperscaler overhead.
