When a user wants to run an application that uses a DL process, they use an API provided by the framework to define the neural network for the process to run and to describe processing details. It powers the Fugaku supercomputer, the fastest supercomputer in the world by TOP500 rankings as of June 2020.

On the other hand, developers who could code while understanding the implementation at the assembler level are few and far between these days, so it would be difficult to gather a team even if that option was a possibility. But we’ll look forward to seeing what happens with big applications. h�b```�v��B ���� His GitHub account name is "kurihara-kk". The A64FX is the world's first processor to implement Scalable Vector Extension (SVE), an extension of the Armv8.2-A instruction set architecture for supercomputers. In this article, we introduced JIT assembler Xbyak_aarch64 for Armv8-A (a key technology required for porting oneDNN), and discussed the development history of Xbyak_translator_aarch64 which accelerates port development.

%� Xbyak is used to generate x64 machine code. We therefore decided to work with Intel and actively submit a pull request to incorporate our changes into the main branch of oneDNN. We are developing Xbyak_aarch64/Xbyak_translator_aarch64/oneDNN optimized for Armv8-A with an open style. The ViON Marketplace™ allows customers to research, compare, procure and manage a full range Everything as-a-Service solutions from leading manufacturers via a single portal. The A64FX features the latest 7nm process, 2.5D packaging technology and microarchitecture which produces optimal power consumption from applications. Such a system will allow scientists to port and co-design their applications, using A64FX key features such as Scalable Vector Extension (SVE) instruction set or the use of HBM2 (32GB per node). It would not be possible to quickly learn what information was encoded, and where. RIKEN and Fujitsu are developing it jointly with the goal of shared use in fiscal 2021. Anandtech reported in June 2020 that the cost of a PRIMEHPC FX700 server, with 2 A64FX nodes, was ¥4,155,330 (c. US$39,000). With two software in our hands, Xbyak_aarch64 and Xbyak_translator_aarch64, we have completed the porting of oneDNN for Armv8-A instruction set. I decided to develop a JIT assembler translator that could generate Armv8-A executable code without (more or less) having to rewrite source code implemented using Xbyak.

I worked late into the night to make sure my answer was thorough. I put a lot of effort into writing the RFC knowing that this would benefit the many users of Fugaku and Armv8-A in the world. He joined Fujitsu Laboratories Ltd in 2012.

Atos will implement its BullSequana eXascale Interconnect (BXI), its networking technology used in Joliot-Curie, to integrate the Fujitsu PRIMEHPC FX700. Incidentally, Xbyak is a software that generates executable code for the x64 instruction set.

In order to port oneDNN to Armv8-A, we needed to create new software that would implement the same functionality as Xbyak for the Armv8-A instruction set. We are recognized worldwide for the quality of our work and have continuously improved our position in analyst rankings.

We’ve been closely following momentum with Fujitsu’s Arm-based A64FX processor, from its inception to its placement inside the world’s most powerful supercomputer. This CPU is based on the ARM version 8.2A processor architecture, and adopts the Scalable Vector Extensions for supercomputers.

Completing Xbyak_aarch64 essentially allowed us to port oneDNN for A64FX. In this post, I will talk about our efforts to port oneDNN (library software used to accelerate DL processes) to Fugaku, and to contribute and incorporate our source code into Intel's main branch of oneDNN. We have also released a version of oneDNN that incorporates Xbyak_translator_aarch64 and that uses a method that indirectly generates JIT code for the Armv8-A instruction set from implementations for the x64 instruction set. After all, from Intel’s perspective this would help collaborating companies.

Good question. The Intel developer was located in the US, and because of the time difference the next question had been sent by the time I woke up. With SVE, you can take a code and run it on a processor that has 128-bit vectors or 512-bit vectors, and it will still run and use all the available hardware.”. He joined Fujitsu Laboratories Ltd. in 2007. It takes only a second to generate executable code, which is a negligible amount in comparison.

We decided first to use Xbyak_aarch64 to port the simplest process, reorder, to the Armv8-A instruction set. Fugaku was aimed to be about 100 times more powerful than the K computer (i.e.
