## Obtaining the Intel® MPI Library

Before installing the Intel® MPI Library, you should check the Intel® Registration Center to see if a newer version or update is available. The version on CD or as listed in your electronic download license letter may not be the most current.

## Installing the Intel® MPI Library

### Pre-Installation Instructions

To install the Intel® MPI Library, you need to use an account that is a member of the Administrators privilege group. Any normal account with Users, Debugger Users or higher user privilege can use the Intel® MPI Library.

You need to unistall the previous version of the Intel® MPI Library (if it is installed).

Note: (SDK) The default installation directory for the Intel® MPI Library <version> is
C:\Program Files (x86)\Intel\MPI\
<version>.<package_num> for the Intel® 64 architecture.
C:\Program Files\Intel\MPI\<version>.<package_num> for the IA-32 architecture.

Note: (RTO) The default installation directory for the Intel® MPI Library <version> is
C:\Program Files (x86)\Intel\MPI-RT\<version>.<package_num> for the Intel® 64 architecture.
C:\Program Files\Intel\MPI-RT\<version>.<package_num> for the IA-32 architecture.

### Installation Instructions

To install the Intel® MPI Library on Windows* OS, do the following:

1. Double-click on the distribution file w_mpi_p_<version>.<package_num>.exe (SDK), w_mpi-rt_p_<version>.<package_num>.exe (RTO)
2. You will be asked to choose a directory in which the contents of the self-extracting installation file will be placed before the actual installation begins. After installation, the files will still be located in this directory. C:\Program Files (x86)\Intel\Download is used by default on the Intel® 64 architecture, C:\Program Files\Intel\Download on the IA-32 architecture.
3. The Welcome dialog will appear. Click Next to continue.
4. Read and accept the license agreement and click Next to continue.
5. You may be asked to provide a path to the license file. A license file that allows installation was sent to you by email along with your serial number. Click Next to continue.
6. You may accept the default installation directory or choose a different directory. All files will be installed to the directory you choose. Click Next to continue.
7. Select the Complete radio-button if you want to install full version of the Intel® MPI Library. If you want to choose the desired components manually, select the Custom. Click Next to continue.
8. The installation program can add the Intel® MPI Library installation directory to the PATH, LIB, and INCLUDE environment variables. Make your selection and click Next to continue. Alternatively, you may set up environment by running the files <installdir>\em64t\bin\mpivars.bat or <installdir>\ia32\bin\mpivars.bat.
9. When the installation completes, click Finish.
10. See the Intel® MPI Library for Windows* OS  Getting Started Guide for more information.

### Cluster Installation

Microsoft* Windows* CCS 2003

The Intel® MPI Library installer uses Microsoft* Compute Cluster Pack (CCP) facilities to determine cluster nodes and to install the Intel® MPI Library on all of them. This feature is available on clusters with Microsoft* Windows* Compute Cluster Server 2003 and the Compute Cluster Pack (CCP) installed and configured package. Set the check box at the installation stage to choose single node or full cluster installation.

Microsoft* Windows* XP, Microsoft* Windows Vista*

The cluster installation feature is not accessible on clusters without the CCP package. Extract the .msi files and use them for silent installation to cluster nodes. Do the following to install the Intel® MPI Library on Microsoft* Windows* XP or Microsoft* Windows Vista* based cluster:

1. Install the Intel® MPI Library on single node.
C:\Program Files (x86)\Intel\Download\w_mpi-rt_p_<version>.<package_num> (RTO) on the Intel® 64 based systems or at
4. Place the license file in the same folder as *.msi files.
5. Login to each cluster node and use the msiexec command to install the Intel® MPI Library on them.

(SDK) Intel® 64 based systems

$> msiexec /i w_mpi_p_<version>_em64t.msi /q IA-32 based systems$> msiexec /i w_mpi_p_<version>_ia32.msi /q

or from the shared folder

Intel® 64 based systems

$> msiexec /i \\host_name\shared_folder\setup\w_mpi_p_<version>_em64t.msi /q IA-32 based systems$> msiexec /i \\host_name\shared_folder\setup\w_mpi_p_<version>_ia32.msi /q

(RTO) Intel® 64 based systems

$> msiexec /i w_mpi-rt_p_<version>_em64t.msi /q IA-32 based systems$> msiexec /i w_mpi-rt_p_<version>_ia32.msi /q

or from the shared folder

Intel® 64 based systems

$> msiexec /i \\host_name\shared_folder\setup\w_mpi-rt_p_<version>_em64t.msi /q IA-32 based systems$> msiexec /i \\host_name\shared_folder\setup\w_mpi-rt_p_<version>_ia32.msi /q

Microsoft* Windows* HPC Server 2008

On Windows HPC Server 2008 disable the User Accounts Control (UAC) during the Intel® MPI Library installation.

Note: The default settings are used during installation through the .msi files.

Note: Use the Microsoft* Remote Installation Service (RIS) or Microsoft* Windows Deployment Service (WDS) to simplify cluster installation.

## Uninstalling the Intel® MPI Library

To uninstall the Intel® MPI Library, select Add or Remove Programs from the Control Panel.
