答:mpi_based原语使用有缓冲的通信,调用者将包含了信息的整个缓冲传送到本地的MPI运行时系统。当调用完成时,这些信息要么被已被发送,要么被拷贝到一个本地的缓冲区。如果使用mpi_isend,调用者仅仅将指向信息的指针传送给本地的MPI运行时系统,然后继续往下执行。调用者需要保证在消息被拷贝或被传送之前不能覆盖它。
This report presents the design and implementation of an adaptive MPI implementation (adaptive-MPI) that allows an MPI application to adapt to respond to changing CPU availability. An adaptive MPI application can start sooner with fewer processors, opportunistically add processors later should they ...
用热力图来衡量MPI应用的locality,适合小规模rank。现有的文献调研发现缺乏对网络特征的度量衡,我们介绍了两个度量衡。用于理解通信的空间关系和如何利用它们进一步做优化。 4.1 MPI层 在MPI层,不存在消息在网络传播的具体路径信息,消息长度和网络利用率。但是关于locality的insight可以在这层看到。比如确定特定的通信参与...
In this paper, we present an MPI-based numerical core dynamics model for simulation of geodynamo and planetary dynamos, and for simulation of core–mantle interactions. The model is developed based on MPI libraries. Two algorithms are used for node–node communication: a "master–slave" ...
In our HPC-RTI, a high speed communication layer based MPI is designed to reduce the communication latency. In this layer, a new process merge method is provided to implement the dynamicMPI process management, and a message sending/receiving mechanism is presented in detail. By this mechanism,...
