User Authorization

The Intel® MPI Library supports several authentication methods under Windows* OS:

I_MPI_AUTH_METHOD

Select a user authorization method.

Syntax

I_MPI_AUTH_METHOD=<method>

Arguments

<method> Define the authorization method.
password Use the password-based authorization. This is the default value.
delegate Use the domain-based authorization with delegation ability.
impersonate Use the limited domain-based authorization. You will not be able to open files on remote machines or access mapped network drives.

Description

Set this environment variable to select a desired authorization method. If this environment variable is not defined, mpiexec uses the password-based authorization method by default. Alternatively, you can change the default behavior by using the -delegate or -impersonate options.
