C-DAC's AUM processor is the cornerstone of India's National Supercomputing Mission, aiming to eliminate dependence on foreign chipsets by 2027.
For decades, India’s fastest supercomputers—from Param Shivay to Airawat—relied on silicon designed in the US or Japan. In 2026, the narrative has shifted. The **Centre for Development of Advanced Computing (C-DAC)** has unveiled the finalized architecture for AUM, a 96-core ARM-based processor that marks India's entry into the elite club of nations capable of designing their own server-grade CPUs.
I. Technical Architecture: The Power of 96 Cores
The AUM processor isn't just a chip; it’s a high-performance "System on Chip" (SoC) built on the TSMC 5nm process node. It utilizes a sophisticated chiplet architecture to maximize yield and performance.
| Feature | Specification |
|---|---|
| CPU Core | ARM Neoverse V2 (Zeus) Architecture |
| Core Count | 96 Cores (Dual 48-Core Chiplets) |
| On-Die Memory | 96GB HBM3 (High Bandwidth Memory) |
| Interconnect | Trinetra-B (200 Gbps Low Latency) |
| Performance | ~10 TFLOPs per node (CPU only) |
II. Strategic Innovation: Beyond the Silicon
1. The Trinetra Interconnect
A supercomputer is only as fast as its slowest connection. C-DAC's Trinetra is an indigenous high-speed network that allows thousands of AUM processors to "talk" to each other with ultra-low latency, rivaling international InfiniBand standards.
2. Direct Liquid Cooling (DLC)
AUM processors are designed for the Rudra server platform, which utilizes C-DAC’s homegrown liquid cooling technology. This reduces power consumption by 20% compared to traditional air-cooled data centers, making India's supercomputers some of the greenest in the world.
III. Why AUM is a Game Changer for India
- Technological Sovereignty: By designing the AUM processor, India eliminates the risk of "backdoors" in critical strategic infrastructure and remains immune to future export restrictions from foreign nations.
- Monsoon Prediction: Enhanced computational power allows the Ministry of Earth Sciences to run high-resolution weather models, improving monsoon accuracy for millions of farmers.
- Defense & Space: From simulating missile trajectories at DRDO to processing satellite imagery at ISRO, AUM provides the "un-hackable" compute core required for national security.
