HP-MPI V1.1 for Windows Release Note

Licensing Policy for Windows

HP-MPI V1.1 for Windows uses FLEXlm licensing technology. A license is required to use

HP-MPI for Windows. Licenses can be purchased from HP’s software depot at

http://www.hp.com/go/softwaredepot, or contact your HP representative.

Demo licenses for HP-MPI are also available from HP’s software depot.

HP-MPI has an Independent Software Vendor (ISV) program that allows participating ISVs

to freely distribute HP-MPI with their applications. When the application is part of the

HP-MPI ISV program, there is no licensing requirement for the end user. The ISV provides a

licensed copy of HP-MPI. Contact your application vendor to find out if they participate in the

HP-MPI ISV program. The copy of HP-MPI distributed with a participating ISV will only

work with that application. An HP-MPI license is required for all other applications.

Licensing for Windows

HP-MPI V1.1 for Windows uses FLEXlm licensing technology. A license file can be named

either as license.dat or any file name with an extension of .lic. The license file must be

placed in the installation directory (default

C:\Program Files (x86)\Hewlett-Packard\HP-MPI\licenses) on all the runtime

systems, and on the license server.

You will need to provide the hostname and hostid number of the system where the FLEXlm

daemon for HP-MPI for Windows will run. The hostid can be obtained by typing the following

command if HP-MPI is already installed on the system:

%MPI_ROOT%\bin\licensing\<arch>\lmutil lmhostid

The hostname can be obtained using the control panel by following Control Panel -> System

-> Computer Name tab.

The default search path used to find an MPI license file is:

"%MPI_ROOT%\licenses:.".

If the license needs to be placed in another location which would not be found by the above

search, the user may set the environment variable LM_LICENSE_FILE to explicitly specify the

location of the license file.
