OCTOPUS Supercomputer Launched by Osaka University

The University of Osaka’s D3 Center has begun trial operations of OCTOPUS, a new high-performance computing and data platform built by NEC to promote open science, with full-scale operations set for December. OCTOPUS delivers 2.293 petaflops of theoretical performance through 140 NEC LX201Ein-1 computing nodes and offers about 1.5 times the performance of the previous system.

A key innovation is the integration of SCUP-HPC, a provenance management technology co-developed by the D3 Center and NEC. SCUP-HPC automatically tracks, records, and visualizes data usage and generation across supercomputers without affecting performance, addressing long-standing challenges of reproducibility, transparency, and efficiency in data-intensive research. Researchers will be able to include computation history IDs from OCTOPUS in their published papers, enabling verification of results and improving research integrity.

This system aims to accelerate scientific computing, including simulations and AI training, while supporting open data sharing across the academic community. NEC also plans to commercialize the provenance management system, positioning it as a foundation for next-generation AI, big data, and industrial applications under its NEC BluStellar initiative.
