mpirun (openmpi) 的问题

我在我的集​​群上本地安装了两个 openmpi 版本：

  • openmpi-1.8.1：当我在此版本下运行 mpirun 时，它给出了一个错误：

    librdmacm: Fatal: unable to open RDMA device
librdmacm: Fatal: unable to open RDMA device
librdmacm: Fatal: unable to open RDMA device
librdmacm: Fatal: unable to open RDMA device

  • openmpi-2.0.0：当我在此版本下运行 mpirun 时，它告诉我：

    mca_base_component_repository_open: shmem "/opt/openmpi-1.8.1/lib/openmpi/mca_shmem_posix" uses an MCA interface that is not recognized (component MCA v2.0.0 != supported MCA v2.1.0) -- ignored

It looks like opal_init failed for some reason; your parallel process is
likely to abort.  There are many reasons that a parallel process can
fail during opal_init; some of which are due to configuration or
environment problems.  This failure appears to be an internal failure;
here's some additional information (which may only be relevant to an
Open MPI developer):
  opal_shmem_base_select failed
  --> Returned value -1 instead of OPAL_SUCCESS

两个版本都安装在 /opt 本地并作为模块加载。看来 openmpi-2.0.0 仍然使用 openmpi-1.8.1 的依赖项，我不明白。

我将非常感激任何诊断和/或解决问题的提示。

提前致谢。

您不应该将它们安装在同一个位置，因为它们的库会相互冲突。openmpi 2.0.0 使用 MCA 接口 2.1.0，openmpi 1.8.1 使用 MCA 接口 2.0.0。因此，您应该将库安装在不同的位置
