Проблемы с mpirun (openmpi)

Я локально установил две версии openmpi в моем кластере:

• openmpi-1.8.1: когда я запускаю mpirun под этой версией, выдает ошибку:

  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: когда я запускаю mpirun под этой версией, он говорит мне:

  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
  

Обе версии устанавливаются локально в /opt и загружаются как модули. Кажется, openmpi-2.0.0 все еще использует зависимости openmpi-1.8.1, чего я не понимаю.

Я буду признателен за любую диагностику и / или советы по ее решению.

Заранее спасибо.
