These options have to do with how MPI processes communicate with the process manager and its proxies. Typically, MPI processes communicate over a Unix socket with the process manager or proxy. --enable-allowport makes it so TCP/IP communication can also be used for this feature. This option only applies to the gforker and remshell process managers (--with-pm=gforker,remshell). --enable-pmiport applies to the Hydra process manager, but is conceptually the same. Hope this helps. Ken On 1/10/19 2:20 PM, Michael L. Stokes via discuss wrote:
Was looking through the configure help output for mpich-3.3 and ran across the configure flags --enable-allowport and --enable-pmiport. Can someone tell me the significance of using these options during the build?
