Getting Started

Before using the MPI tuner for Intel® MPI Library, ensure that the library, scripts, and utility applications are installed. See the
Intel® MPI Library Getting Started Guide
for instructions.
The general workflow of using the MPI tuner is as follows:
  1. Create optimized configuration files through the
    mpitune
    utility.
  2. Use the configuration files through the
    –tune
    option of the
    mpiexec
    command during regular execution.
Usage instructions for specific tasks are given in detail further in this tutorial and rely on these general steps.
Note
Before you use the MPI tuner, you can check the tasks to be executed. Use the
--scheduler-only (-so)
option to see the scope of mpitune work before the real run:
> mpitune ... –so
.
