HP-MPI Version 2.2 for Linux Release Note

HP-MPI V2.2 for Linux Release Note

Licensing Policy

HP-MPI 2.2 for Linux uses FLEXlm licensing technology. A license is required to use HP-MPI

for Linux. Licenses can be purchased from HP’s software depot at

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

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

If you’re running on an HP XC system, no HP-MPI license is required at runtime because we

use the XC system license.

Licensing

HP-MPI 2.2 for Linux 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 /opt/hpmpi/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 Linux will run. The hostid, which is the MAC address of eth0, can be

obtained by typing the following command if HP-MPI is already installed on the system:

% /opt/hpmpi/bin/licensing/<arch>/lmutil lmhostid

Or:

% /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=/home/hpmpi, license files will be 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
