mSMS: PGAS Runtime with Efficient Thread-based Communication for Global-view Programming
Hiroko Midorikawa, Kenji Kitagawa, Yugo Sakaguchi · 2019
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.
