^OpenSHMEM. The Programming Models and Languages team is focused on developing the OpenSHMEM programming model for extreme scale systems. ……Currently, the team partners with NVIDIA, University of Tennessee, Knoxville, Florida State University and Paratools. …… UCX provides communication interfaces, and protocols for efficiently implementing parallel programming models such as MPI, OpenSHMEM, and task-based models.
^Epiphany Architecture Reference(PDF). The Epiphany architecture defines a multicore, scalable, shared-memory, parallel computing fabric. It consists of a 2D array of compute nodes connected by a low-latency mesh network-on-chip（英语：Network on a chip）. ……Local memory in each mesh node that provides 32 Bytes/cycle of sustained bandwidth and is part of a distributed, shared memory system.
