在使用MPI框架中,需要多机进行通信进行并行计算;现在配置多个主机进行运行mpi程序,并进行通信;涉及到ssh无密码和nfs文件系统配置;
参考文档:
多机配置步骤:
运行状态:可见已经在两个节点上运行;
mpirun -n 10 -hosts client,master ./mpi_hello_world
Hello world from processor jn-1, rank 8 out of 10 processors
Hello world from processor jn-1, rank 6 out of 10 processors
Hello world from processor jn-1, rank 4 out of 10 processors
Hello world from processor jn-1, rank 0 out of 10 processors
Hello world from processor jn-1, rank 2 out of 10 processors
Hello world from processor jn-4, rank 5 out of 10 processors
Hello world from processor jn-4, rank 7 out of 10 processors
Hello world from processor jn-4, rank 1 out of 10 processors
Hello world from processor jn-4, rank 3 out of 10 processors
Hello world from processor jn-4, rank 9 out of 10 processors
节点host样本:主机要测试主从节点网络互相连通,此配置基于以太网配置;
$ cat /etc/hosts (master)
127.0.0.1 localhost
#127.0.1.1 1944
#MPI CLUSTER SETUP
172.50.88.22 master
172.50.88.56 slave1
172.50.88.34 slave2
$ cat /etc/hosts (client)
127.0.0.1 localhost
#127.0.1.1 1947 (在超算中,也经常使用数据进行编号节点)
#MPI CLUSTER SETUP
172.50.88.22 master
172.50.88.54 slave3
