HP-MPI Version 2.3.1 for Linux Release Note

If the license needs to be placed in another location, which is not found by the previous
search, you can set the environment variable LM_LICENSE_FILE to explicitly specify
the location of the license file.
For more information, see http://licensing.hp.com.
6.2.1 Installing License Files
A valid license file contains the system hostid and the associated license key. License
files can be named either as license.dat or any name with extension of *.lic (for
example mpi.lic). Copy the license file under the directory /opt/hpmpi/licenses.
The command to run the license server is:
% $MPI_ROOT/bin/licensing/<arch>/lmgrd -c mpi.lic
6.2.2 License Testing
To check for a license, build and run the hello_world program in $MPI_ROOT/help/
hello_world.c. If your system is not properly licensed, the following error message
appears:
(“MPI BUG: Valid MPI license not found in search path”)
6.2.3 Merging Licenses
Newer HP-MPI licenses use the INCREMENT feature that enables separate HP-MPI
licenses to be used in combination by concatenating files. For example:
License 1:
SERVER myserver 0014c2c1f34a
DAEMON HPQ
INCREMENT HP-MPI HPQ 1.0 permanent 8 9A40ECDE2A38 \
NOTICE="License Number = AAAABBBB1111" SIGN=E5CEDE3E5626
License 2:
SERVER myserver 0014c2c1f34a
DAEMON HPQ
INCREMENT HP-MPI HPQ 1.0 permanent 16 BE468B74B592 \
NOTICE="License Number = AAAABBBB2222" SIGN=9AB4034C6CB2
In this example, License 1 is for 8 ranks, and License 2 is for 16 ranks. The two licenses
can be combined into a single file:
SERVER myserver 0014c2c1f34a
DAEMON HPQ
INCREMENT HP-MPI HPQ 1.0 permanent 8 9A40ECDE2A38 \
NOTICE="License Number = AAAABBBB1111" SIGN=E5CEDE3E5626
SERVER myserver 0014c2c1f34a
DAEMON HPQ
INCREMENT HP-MPI HPQ 1.0 permanent 16 BE468B74B592 \
NOTICE="License Number = AAAABBBB2222" SIGN=9AB4034C6CB2
The result is a valid license for 24 ranks.
