HP-MPI Version 2.3.1 for Linux Release Note

6 Licensing Information
6.1 Licensing Policy
A license is required to use HP-MPI for Linux. You can purchase licenses from the HP
software depot at http://www.hp.com/go/softwaredepot, or by contacting your HP
representative.
Demo licenses for HP-MPI are also available from the HP software depot.
No separate HP-MPI license is required on an HP XC system.
6.2 License Installation and Testing
HP-MPI V2.3.1 for Linux uses FLEXnet Publisher licensing technology. A license file
can be named either as license.dat or any file name with a .lic extension. The
license file must be placed in the installation directory (default location /opt/hpmpi/
licenses) on all runtime systems, and on the license server.
HP-MPI V2.3.1 for Linux optionally supports redundant license servers. The HP-MPI
License Certificate includes space for up to three license servers. Either one license
server, or three license servers are listed on the certificate. To use a single license server,
follow the directions below. To use three redundant license servers, repeat the steps
below for each license server.
You must provide the hostname and hostid number of each system where the FLEXnet
daemon for HP-MPI for Linux runs. The hostid, which is the MAC address of eth0, can
be obtained by typing one of the following commands if HP-MPI is already installed
on the system:
• % /opt/hpmpi/bin/licensing/<arch>/lmutil lmhostid
• % /sbin/ifconfig | egrep "^eth0" | awk '{print $5}' | sed s/://g
The hostname can be obtained by entering the command hostname.
The default search path used to find an MPI license file is:
%$MPI_ROOT/licenses:/opt/hpmpi/licenses:
For example, if MPI_ROOT is set to /home/hpmpi, license files are searched in the
following order:
/home/hpmpi/licenses/license.dat
/home/hpmpi/licenses/*.lic
/opt/hpmpi/licenses/license.dat
/opt/hpmpi/licenses/*.lic
./license.dat
./*.lic
