认识三个MPI函数: (1)获取当前进程标识函数:int MPI_Comm_rank(MPI_Comm comm,int *rank) (2)获取通信域包含的进程总数函数:int MPI_Comm_size(MPI_Comm comm,int *size) (3)获取本进程的机器名函数:int MP
此函数通常与MPI_Comm_rank函数一起使用,以确定可用于特定库或程序的并发量。MPI_Comm_rank函数指示在 0 到size-1范围内调用它的进程的排名,其中size是使用MPI_Comm_size函数检索的。 备注 初始化后,没有标准的方法来更改进程数。 要求 产品 HPC Pack 2012 MS-MPI 可再发行程序包、HPC Pack 2008 R2 MS-MPI...
后来在外网上找到了答案: https://stackoverflow.com/questions/29264640/mpiexec-and-python-mpi4py-gives-rank-0-and-size-1 也就是说mpi4py的编译时的mpi环境与运行时的mpi环境不同,于是才会出现这样的问题。 通过python查询当前mpi4py的编译环境: import mpi4py mpi4py.get_config() 发现这个MPI编译环境和...

Hello world: rank 0 of 1 running on node4...so while the job is farmed out to the 4 nodes, each node thinks that it's the master, and needs to do the propagation etc. Have I missed something embarassingly obvious here? Any help would really be great!Thanks Translate 0 Kudos ...
The MPI_Comm_rank function indicates the rank of the process that calls it in the range from 0 to size-1, where size is retrieved by using the MPI_Comm_size function.Note There is no standard way to change the number of processes after initialization has taken place....
