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 (.lic). A license file that allows installation was sent to you by email along with your serial number. Click Next to continue.

  10. See the Intel® MPI Library for Windows* OS  Getting Started Guide for more information.

Cluster Installation

The Intel® MPI Library installer has a silent installation mode that helps you to install the Intel MPI Library on clusters with many nodes. Do the following to install the Intel® MPI Library on Microsoft* Windows* CCS 2003, Microsoft* Windows* HPC Server 2008, Microsoft* Windows* XP or Microsoft* Windows Vista* based cluster:

  1. Go to the head node of the cluster.
  2. Copy the license file to the C:\Program Files(x86)\Common Files\Intel\Licenses on the Intel® 64 based systems or C:\Program Files\Common Files\Intel\Licenses on the IA-32 based systems. This step is not necessary for the RTO package.
  3. Open command line and go to the folder where the distributive package located.
  4. Execute the following command: w_mpi[-rt]_p_<version>.<package_num>.exe --silent -a install --eula=accept
  5. Wait for completion.

On Microsoft* Windows* CCS 2003 and Microsoft* Windows* HPC Server 2008 based cluster, the installer installs all the Intel® MPI Library components on all compute nodes in addition to the head node. On Microsoft* Windows* XP and Microsoft* Windows Vista* based cluster, you need to repeat steps 2-5 on each compute node. The default installation location is C:\Program Files(x86)\Intel\MPI\<version> (SDK), C:\Program Files (x86)\Intel\MPI-RT\<version> (RTO) on the Intel® 64 based systems or C:\Program Files\Intel\MPI\<version> (SDK), C:\Program Files\Intel\MPI-RT\<version> (RTO) on the IA-32 based systems.

The installer on Windows* OS performs Active Directory* setup required for the domain-based authorization with the delegation ability. The domain administrator rights are required, otherwise this setup will not be performed. See the Intel® MPI Library Reference Manual for more information.
