[InsideHPC] ARM-based Fugaku Supercomputer on Summit of New Top500 – Surpasses Exaflops on AI Benchmark

The new no. 1 system on the updated ranking of the TOP500 list of the world’s most powerful supercomputers, released this morning, is Fugaku, a machine built at the Riken Center for Computational Science in Kobe, Japan. The system turned in a High Performance LINPACK (HPL) result of 415.5 petaflops (nearly half an exascale), outperforming Summit, the former no. 1 system housed at the U.S. Dept. of Energy’s Oak Ridge National Lab, by a factor of 2.8x.

Fugaku, powered by Fujitsu’s 48-core A64FX SoC, is the first ARM-based system to take the TOP500 top spot. The system, which has 158,976 nodes, blew through the exascale (a billion billion calculations per second) milestone in single precision calculations, often used in machine learning and AI applications. On the HPL-AI benchmark, designed to measure HPC performance on machine/deep learning workloads, Fugaku registered peak performance of 1.45 exaflops, according to Jack Dongarra, Distinguished Professor of Computer Science at the University of Tennessee, who helped create the TOP500 list in 1993.

“This is an impressive machine,” Dongarra told us. “It has great potential. They’ve run a number of applications already on the Fugaku system, and I expect to see many good things come out of it. It’s a very well balanced machine. It was designed to do supercomputing – that is to say, it wasn’t cobbled together from commodity processors and GPUs. It was designed specifically for this high end, high performance computing.”
The 20s are going to be a very interesting with the adoption of ARM.

This is pretty impressive feat considering it is built with only CPUs and manages to match/outperform CPU/GPU based SC in efficiency.

Impressive yes, but considering it has 3x the cores and 2.8x the power requirement and it is extremely dedicated hardware, it is something with a very focused use.
It is I expect more complicated to write software to over summit which was built for multiple uses. So it will be more interesting to see the how well they are going to add software to it.

And of course, it will be interesting to see how frontier is going to be sometime next year, going to be built for 1.5 exaflops based on AMD hardware. Maybe AMD will finally be back at the very top again and not have to relay on nvidia hardware to be there.

Coding for ARM is easier than coding for a GPU let alone a new language like AMD's HIP.

Well AMD HIP has been around for close to 5 years, and with their new hardware, it is getting better. Not cuda better, but better than all their GPGPU APIs from before.
And considering they are using their own tailored software, I expect no, it is not easier. I expect it will be similar in complication. Only difference is that AMD will provide API to make it easier to use the GPU power, while here they will need custom software to allow utilizing such amount of threads running in the system.
Those who already been writing for GPU (in the last decade), should feel relatively at home. Especially since summit has been utilized by so many academies.
