*Further Information*

*This chapter presents the XcalableMP on the Fugaku supercomputer, the Japanese flagship supercomputer developed by FLAGSHIP2020 project in RIKEN R-CCS. The porting and the performance evaluation were done as a part of this project, and the XcalableMP is available for the Fugaku users for improving the productivity and performance of parallel programing. The performance of XcalableMP on the Fugaku is enhanced by the manycore processor and a new Tofu-D interconnect. We are now working on the next version, XcalableMP 2.0, for cutting-edge high-performance systems with manycore processors by multithreading and multi-tasking with integrations of PGAS model and synchronization models. We conclude this book with retrospectives and challenges for future PGAS models.*
