In the field of nuclear power, supercomputers are essential for conducting large-scale and complex simulations. In collaborative research and major projects, scientists dispersed across multiple locations need to share simulation results for analysis and discussion. However, transferring massive data from supercomputers over the network incurs significant costs. We have developed a particle-based In-situ visualization method, IS-PBVR, specifically tailored for supercomputers. Through an In-situ control mechanism using file-based compression, interactive visualization of compressed particle data can be transferred to user PCs. In this study, we utilize the In-situ control of IS-PBVR to deliver visualization data to user PCs at various locations, enabling remote VR visualization at multiple points. We are actively developing In-situ multi-point remote VR visualization technology, applying this technique to fluid simulations on supercomputers and validating its effectiveness by sharing results across multiple user PCs.
