Towards a Java Virtual Machine for Processing-In-Memory (Extended Abstract) Ichinose, Kazuki Sato, Shigeyuki Ugawa, Tomoharu Java VM Processing-in-Memory Offloading Data parallelism Processing-in-Memory (PIM) is a computing paradigm in which computation takes place in or near memory devices, offering high-bandwidth yet energy-efficient data-parallel processing. Real-world PIM systems have recently emerged, and SPMD-style programming in C is supported there. However, high-level object-oriented programming in managed languages has never been studied. Pursuing high-level programming for offloading Java applications to PIM processors, we are developing a Java framework to support it. As a status report on our project, we present our prototype Java VM built upon a real-world PIM system and experimentally demonstrate its scalability. The experimental results showed the potential of our Java VM on the PIM system with thousands of PIM processors.
