\u00a0SAKURA internet Inc. (Headquarters: Osaka City, Osaka Prefecture; President: Kunihiro Tanaka; hereinafter \u201cSAKURA internet\u201d), which provides digital infrastructure services, has achieved 22nd place worldwide in the HPCG benchmark, which evaluates system performance under conditions close to real-world applications, including memory access and inter-node communication.
\nIn addition, SAKURAONE ranked 63rd in the TOP500*1<\/span>, the global ranking of supercomputer processing performance.<\/p>\n

\"\"<\/p>\n

\u00a0These rankings were announced at ISC2026 (ISC High Performance 2026), the international conference on High Performance Computing (HPC), currently being held in Hamburg, Germany.<\/p>\n

\u00a0SAKURAONE was jointly developed by SAKURA internet Research Center, an in-house research organization of SAKURA internet, and Prunus Solutions, Inc., a group company specializing in HPC system integration.
\n\u00a0These results demonstrate that SAKURAONE can perform large-scale computational workloads such as training and inference of large language models (LLMs) with high speed and efficiency. They confirm that SAKURAONE offers internationally competitive performance as a computing platform for the AI era.<\/p>\n

\u00a0This system utilizes NVIDIA HGX B200 systems and achieved 37.79 petaflops (PFLOPS) on the LINPACK benchmark*2<\/span>.
\n\u00a0Furthermore, in the HPCG benchmark, which evaluates overall system performance under conditions close to real-world usage, including memory bandwidth and inter-node communication, the system recorded an effective performance of 1,076.97 teraflops (TFLOPS). This result demonstrates not only high computational capability but also efficient data handling, supporting strong real-world application performance.<\/p>\n

\u00a0In addition, SAKURAONE incorporates advanced technologies such as high-density cabling, the use of open-source technologies, and Direct Liquid Cooling (DLC)*3<\/span>. These combine to form a high-performance and stable computing infrastructure that delivers high value to customers engaged in AI development and R&D efforts.
\n\u00a0Moreover, the insights gained through the introduction and operation of these advanced technologies are shared both domestically and internationally through activities such as presentations of academic papers at international conferences and contributions to open-source communities*4<\/span>. Through these efforts, SAKURA internet contributes to the advancement of the AI and HPC fields and the overall improvement of technology throughout the industry.<\/p>\n

\u00a0SAKURA internet continues to provide infrastructure that supports the research and development of cutting-edge technologies, including generative AI, through its managed supercomputer SAKURAONE, and remains committed to achieving world-class performance and reliability. Furthermore, SAKURA internet continues to contribute to the sustainable development of digital society through ongoing investment in next-generation GPU infrastructure and the creation of high-value-added services.<\/p>\n
