摘　　要：开源通信框架在编程模型和互连接口之间定义标准化的通信编程接口,提供了独立于互连网络特性的高性能通信操作,提高了编程模型在新型互连网络上的开发效率。通过设计与实现多通道数据传输协议,解决了通信框架在天河互连网络上实现时的性能和扩展性问题。测试数据表明,天河互连网络上的通信框架具有很低的软件层开销,提供了接近于互连硬件设计指标的通信性能,为拓展天河互连网络对各种编程模型和分布式计算框架的高效支持提供了良好的基础。Open source communication framework defines standard communication APIs between the parallel programming model and the interconnection network,which provides high performance communication operations independent from the characteristics of interconnection network.Its purpose is to improve the efficiency of developing programming models on new interconnection networks.The performance and scalability of communication frameworks on TH-express interconnection are solved through the design and implementation of new multi-channels data transfer protocols.Performance test shows that open source communication frameworks have low software overhead and provide high performance data transfer very close to the design performance of TH-express interconnection.This provides a good foundation for supporting parallel programming models and distributed computing frameworks efficiently on TH-express interconnection.
