摘要

单侧追加表示一类新的单侧操作，可用于将来自多个通信源的消息聚合到单个目标缓冲区中。分析了这种新的通信范式对OpenSHMEM并行编程模型和应用程序的影响。讨论了实现注意事项，并介绍了使用Portals 4网络API的加速实现。NAS整数排序基准的初步实验结果表明，这种新操作可以显著提高此类应用的通信性能。

One-Sided Append: A New Communication Paradigm For PGAS Models

One-sided append represents a new class of one-sided operations that can be used to aggregate messages from multiple communication sources into a single destination buffer. This new communication paradigm is analyzed in terms of its impact on the OpenSHMEM parallel programming model and applications. Implementation considerations are discussed and an accelerated implementation using the Portals 4 networking API is presented. Initial experimental results with the NAS integer sort benchmark indicate that this new operation can significantly improve the communication performance of such applications.
