Optimized Architecture Enhances the Exascale Environment
Frontier contains optimized 3rd Gen AMD EPYC CPUs for high-performance computing and artificial intelligence, as well as AMD Instinct MI250X accelerators, both tailored specifically for exascale environments. AMD researchers and engineers drew from the company’s more than 50 years of history in building processors, to create something that is too capable of achieving exascale performance, Malaya said.
They added specialized architectural features to help substantially improve performance. “We’ve had to make improvements in our hardware, we’ve had to make improvements in our software and we worked with the endline users and domain scientists to improve their algorithms as well,” he says.

Optimizing algorithms to reduce the movement of data through the supercomputer — in particular, making it move around less — can cut energy consumption dramatically, he says, and does not affect the computational power.
“The fact that the world’s fastest machine is also the most energy-efficient is just simply amazing,” Thomas Zacharia, lab director at ORNL, said during a press conference in May.
Supercomputer Technology Can Scale to Other Systems
The technology behind Frontier’s speed and energy-efficiency is scalable to other architectures, Malaya says. For instance, the optimized code used to modify the software running the algorithms is available to use “so that anyone who has AMD hardware can take advantage of those algorithms,” he adds.
And while Frontier is composed of more than 9,000 nodes — a block of 1 CPU and 4 GPUs — the components of the system are available to other enterprises, allowing them to “take advantage of all the optimizations, all the software, all the work we’ve done on that scale. It’s a very scalable solution,” he says.

Most large-scale data centers rely on similar CPUs and GPUs to do their work. The technology is also critical for artificial intelligence and machine learning projects.
“The work from Frontier helps lead us to the next generation of products, which we believe is going to be a lot more efficient, have a lot more performance and be usable for the broader industry,” says Mahesh Balasubramanian, director of product marketing for the AMD accelerated GPU business unit.
