THE PROBLEM

Pressures that reshape infrastructure

Efficiency, isolation, and sovereignty are all on the same list now.

Surging data flows

Creating critical throughput and latency constraints at scale.

Inefficient infrastructure

Leaving CPU and GPU resources underutilized.

Fragmented infrastructure

Limits secure and efficient resource sharing across tenants.

Escalating threats

Require robust zero-trust architectures with strong hardware isolation.

Limited sovereignty

Undermines trusted control over data and infrastructure.

Solution

DPUs are an essential pillar of modern infrastructure

Kalray's MPPA®-based DPUs are designed to enable efficient, secure, and sovereign infrastructure alongside CPUs and GPUs: from AI factories and HPC fabrics to storage, networking, security, and the telco edge. Built on a modular architecture, they eliminate bottlenecks, restore CPU and GPU efficiency, and bring intelligent processing into the data path itself.
