PATH=$PATH:/usr/MPICH-install/bin?? //新增加的#Source .bashrc?mpd配置文件中设置密码#cd $HOME#touch .mpd.conf#chmod 600 .mpd.conf?????? //权限设置为只有自己有读写权限在超级用户下：#cd /etc#vi mpd.conf????? 写入 secretword=jsi 并保存#chmod 600 /etc/mpd.conf?单机测试#mpd #mpdtrace????? //显示本机名为成功#mpiexec –n 1 /bin/hostname#mpdallexit?SSH配置??? 修改所有机器上的/etc/hosts文件为如下内容 localhost.localdomain localhost90 node090 node02……??? 创建SSH密钥（root目录）#ssh-keygen –t rsa?? //其中-t rsa指密钥类型。这样就生成了~/.ssh#cd .ssh#cp id_rsp.pub authorized_keys?? //生成authorized_keys文件#cd..#ssh node01?????? //建立本身的信任连接??? 设置其他机器#ssh-keygen –t rsa???????? //生成.ssh文件夹#scp 90:/root/.ssh/* /root/.ssh#scp 90:/etc/hosts??? 对每个节点执行#ssh node01#ssh node02……????? //提示输入密码-登陆，为成功?NFS配置1 服务器端??? #/etc/rc.d/init.d/nfs start??????? //启动nfs服务??? #vi /etc/export???????? //编写exports文件，写入需共享目录eg.? /public/mpi node01(rw) node02(rw) …2 客户端??? #showmount –e nfshost????????? //查看NFS服务器上共享资源??? #mount nfshost:目录本机挂载目录eg. #mkdir /public/mpi????? #mount node01:/public/mpi /public/mpi??? #unmount /public/mpi //卸载(如果需要的话)?创建主机名称集合文件/root/mpd.hosts#vi mpd.hosts文件内容如下：node01node02…?通过mpd.hosts运行集群系统#mpdboot -n num -f mpd.hosts?? //num为要起动的机器个数#mpdtrace #mpdallexit?MPI并行程序的编译与执行#mpdboot -n num -f mpd.hosts#mpicc cpi.c –o cpi#mpiexec –n num cpi#mpdallexit?MPI简介
