Questions tagged [mpiexec]

`mpiexec` is the command used to start [tag:MPI] applications. It replaces many earlier non-standard commands used by various implementations (including `mpirun`).

mpiexec is the command used to start applications. It replaces many earlier non-standard commands used by various implementations (including mpirun). All MPI implementations are now required to provide a command mpiexec to launch applications. This can be found in the most recent version (3.0) of the MPI Standard in Section 8.8, Portable MPI Process Startup

In some instances, mpiexec can also be used to refer to the process launcher that actually launches each local and remote instance of the application, however this is usually better described as the process launcher.
