MPI

Windows MPI

On Windows, OpenEye applications use the Microsoft implementation of MPI (MS-MPI). If not already installed, MS-MPI can be installed from the setup file provided in the bundle at C:\Program Files\OpenEye-applications<version>\mpi\MSMpiSetup.exe.

MPI on Windows requires a valid network connection. If no connection exists MPI will not run. A network connection can be created by installing a Microsoft loopback adapter. Please contact support@eyesopen.com for more details.

Note

Multi-node MPI is not currently available in Windows as it is not supported in MS-MPI

Open MPI

On Linux and MacOS, OpenEye applications use the Open MPI implementation of MPI, found at http://www.open-mpi.org/. The applications package includes a full Open MPI install, so no additional software is needed.

There are two requirements to run under Open MPI.

  • Every machine in the cluster must have the same version of the application installed.

  • The path to the application’s bin directory must be in the PATH environment variable on all machines, and be positioned before any other locations that may contain MPI executables (orted, mpirun, etc.).

Using Open MPI

To run under Open MPI on a single machine:

> [application executable] -mpi_np [number of processes] [other application options]

To run Open MPI on multiple machines, begin by generating a text file that will include the MPI hosts you plan to use and the number of processes on each (for this example, we’ll call this file hosts). The file should contain a line for each machine with the name of the machine, a space, then slots=N, where N is the number of processors for your run. For this example, the file looks like this:

c1 slots=4
c2 slots=4
c3 slots=4
c4 slots=4
c5 slots=4

The following command-line will then start a job with one master and 19 slaves.

> [application executable] -mpi_hostfile hosts [other application options]

The master will be on c1, where the job is being started. All the input/output for the run is controlled from the master machine, and all results and logging information are combined.
