IMPI Python集群运行报错:

Posted 2020-10-31 Hello woooo

之前用C语言的MPI和对应的hostfile尝试集群运行，已经通过验证是没有问题的。

使用IMPI的mpirun就发生了上述问题，还在尝试解决中

似乎和原来的OpenMPI 的命令行参数不太一样，尝试了几个都没法之后，只用用命令
/opt/intel/intelpython2/bin/mpirun -help | grep host
来查找所有和host有关的配置参数来看一遍了，输出如下

$ /opt/intel/intelpython2/bin/mpirun -help | grep host
    -f {name} | -hostfile {name}     file containing the host names
    -hosts {host list}               comma separated host list
    -host {hostname}                 host on which processes are to be run
    -hostos {OS name}                operating system on particular host
    -perhost <n>                     place consecutive <n> processes on each host
    -ppn <n>                         stand for "process per node"; an alias to -perhost <n>
    -grr <n>                         stand for "group round robin"; an alias to -perhost <n>
    -localhost                       local hostname for the launching node
