GMO Internet to Exhibit as Top Sponsor at JANOG58 Meeting in Matsuyama, Japan's Largest Network Technology Conference

GMO Internet, Inc. (President and CEO: Masatoshi Ito, hereinafter referred to as GMO Internet), part of the GMO Internet Group, will exhibit as a top sponsor with its GPU cloud service for AI development and learning infrastructure, "GMO GPU Cloud," at the "JANOG58 Meeting in Matsuyama" (hereinafter, JANOG58), to be held from July 15 (Wed) to July 17 (Fri), 2026, at the Ehime Prefectural Culture Hall.

Maximizing GPU computational performance in large-scale distributed learning requires low-latency, high-bandwidth networks between multiple nodes (servers) and stable storage. The performance of GPU cloud is inseparable from network design, and the purpose of this exhibition is to share and deepen knowledge within "JANOG," Japan's largest community of network engineers.

The "GMO GPU Cloud" booth will feature live demonstrations of 400Gbps (a super-high-speed communication standard capable of transferring 400 gigabits or 50 gigabytes of data per second) wire-speed connectivity, as well as demonstration data of remote distributed AI infrastructure utilizing IOWN APN (*1). We aim to provide a venue for technical exchange and information sharing with attending engineers.

Exhibit 2: Japan's First Adoption of NVIDIA Spectrum-X - AI-Specific Network Design

We will explain why NVIDIA Spectrum-X, adopted for the first time by a Japanese cloud provider (*2), is effective for AI distributed learning. Engineers will directly explain the core design aspects, such as latency reduction through adaptive routing and throughput stabilization in multi-tenant environments.

Exhibit 3: Publication of Actual Measurement Values for Remote GPU Learning Between Tokyo and Fukuoka - IOWN APN Utilization Demonstration

We will release the results of a demonstration of AI infrastructure that remotely connected GPUs and storage between Tokyo and Fukuoka using NTT's next-generation optical communication infrastructure "IOWN APN." This demonstration by NTT East, NTT West, QTnet, and GMO Internet will showcase the potential for new AI infrastructure designs that transcend the geographical constraints of data centers. Actual measurement values in a remote environment and comparative data with a local environment will be available for viewing at the booth.
