A new partitioned global address space (PGAS) runtime, mSMS, with efficient thread-based communication is proposed in this work. The mSMS runtime system transparently invokes system threads behind a user program, to support the concurrent execution of remote communication and calculations, and manage dynamic thread creation/deletion in the user program. Two types of applications-stencil computations with synchronous static data access and Barnes-Hut problems with asynchronous dynamic data access-are evaluated. The mSMS achieves performance comparable to or better than that of MPI and other PGAS languages.

Various partitioned global address space (PGAS) languages capable of providing global-view programming environments on multi-node computer systems have been proposed to improve programming productivity in high-performance computing. However, several PGAS languages often require a detailed description of the remote data access, similar to descriptions used in message passing interface one-sided communications. Some PGAS languages have limitations pertaining to remote data access and recommend their local-viewprogramming models, rather than the global-view ones, due to performance-related reasons. In this study, we propose SMint, which is an application programming interface that provides a global-view programming model with a software distributed shared memory mSMS as the runtime. Using stencil computation as a typical processing method, the performance and programmability of SMint have been compared with those of XcalableMP and Unified Parallel C, which are well-known examples of PGAS languages based on the C language. It was found that SMint achieved the best performance under the ideal global-view programming model.
