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. |
<not set> | Use the default bootstrap mechanism, not relies on hydra_service.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. The setting of I_MPI_AUTH_METHOD to any value above leads to the usage of service-based bootstrap. Alternatively, you can change the default behavior by using the -delegate or -impersonate options.
For more details, see the Developer Guide, section User Authorization.
