Features

• The Intel® MPI Library pins processes automatically. Use the I_MPI_PIN and related environment variables to control process pinning.
  
  
• The Intel® MPI Library enhances message-passing performance on DAPL -based interconnects by maintaining a cache of virtual-to-physical address translations in the MPI DAPL data transfer path. To disable the translation cache completely, set the environment variable I_MPI_RDMA_TRANSLATION_CACHE to disable
  
  
• An MPI application inherits the current working directory of the mpiexec command at the time of its invocation. Use the -gwdir or -wdir options to override this
  
  
• Use thread safe version of the Intel® MPI Library in conjunction with Intel® MKL
  
  
• Set the OMP_NUM_THREADS environment variable to 1 to run application linked against non thread safe version of the Intel® MPI Library
