C-DAC AUM Chip: India’s First Indigenous Arm-Based CPU

With its most recent development, the C-DAC AUM CPU, India’s Centre for Development of Advanced Computing (C-DAC) has set its eyes on developing the high-performance computing (HPC) industry. This cutting-edge CPU, code-named Zeus, is based on the ARM Neoverse V1 core architecture and promises to transform HPC’s capabilities in the digital era. Let’s examine this revolutionary development in further detail.

C-DAC is committed to meeting a variety of computing needs, including those for data centres, augmented reality/virtual reality (AR/VR) applications, and smart devices and the Internet of Things (IoT).

The entry-level market for low-power and reasonably priced processors will be especially targeted by the Vega CPU family, which has two and quad-core architectures. In order to provide companies with effective computing solutions, C-DAC plans to meet at least 10% of India’s chip demand. The business also intends to launch octa-core chips within the following three years as a replacement for the popular Dhruv and Dhanush Plus processors.

National Supercomputing Mission with Power-Efficient HPC

C-DAC is assiduously developing a power-efficient HPC processor to aid the National Supercomputing Mission (NSM) programme. This chip, known as the C-DAC AUM, is made especially to efficiently manage heavy workloads. The AUM CPU has an impressive 96 cores and uses the ARM Neoverse V1 core architecture. These cores are split across two chiplets, each of which contains 48 V1 cores. For difficult HPC workloads, its novel architecture offers optimum performance and improved scalability..

Architecture of the C-DAC AUM CPU

The C-DAC AUM CPU is distinguished by its outstanding architectural characteristics, which offer a solid basis for high-performance computation. The memory, I/O, C2C/D2D interface, cache, security, and MSCP sub-systems are all included in every AUM CPU chiplet. The two A48Z-based chiplets work together effortlessly thanks to a D2D chiplet connection on the same interposer, which boosts productivity and data transfer speeds. Notably, the CPU has a 96 MB L2 cache and a 96 MB system cache, which improves its speed even further.

Memory Configuration

A unique triple-memory subsystem is used by the C-DAC AUM CPU, combining on-die, inter-poser, and off-chip memory options. The AUM CPU has outstanding memory bandwidth thanks to its 64 GB of HBM3-5600 memory and an extra 96 GB of HBM3 memory on-die. Additionally, its 8-channel DDR5-5200 memory, which scales up to 16 channels for a maximum total bandwidth of 332.8 GB/s, provides efficient data processing for even the most difficult computing operations.

the Power: Performance and Scalability

With clock rates ranging from 3.0 to 3.5 GHz, the C-DAC AUM CPU displays its performance capability. The performance of a single CPU-only node with the C-DAC AUM can reach up to 10 TFLOPs. This extraordinary CPU can handle up to four industry-standard GPU accelerators in a dual-socket server configuration and offers an astonishing 4.6+ TFLOPs per socket. The AUM CPU enables easy integration and extension opportunities for many computing environments by supporting 64/128 PCIe Gen 5 lanes and being CXL compatible.
