A

Open SM (1) should only be installed on one node in the cluster where it will 

be used. If desired, Type 1 for Open SM.

8.

Type p to start the installation.

The installer will uninstall older OFED RPMs, then asks for input for a series 
of operations. You can accept the defaults by pressing ENTER. Note the 
following cases:

Install MPI with prefix compatible with mpi-selector 
(/usr/mpi/qlogic) [y]: y

This default allows you to use the mpi-selector to choose between 

different MPI implementations.

If you type y, make sure, after installation, that the environment variable 
$MPICH_ROOT is set to the same prefix that is used here 

(/usr/mpi/qlogic). When set, the $MPICH_ROOT variable allows QLogic 

MPI to correctly locate header and library files for MPI compilation and 
running parallel jobs. Typing n causes QLogic MPI to be installed in the 
default directory /usr.
The next case is:

Configure OFED IP over IB IPV4 addresses now? [n]: 

Type y if the IB IPV4 addresses and netmasks are available, and you want 
to enter them now. Type n if the IB addresses are not available or you want 
to add them later. IPoIB can be configured manually by following the 
instructions in 

Finally, QLogic recommends answering n to the following:

Enable QLogic SRP (qlgc_srp) to autostart? [y]: n
Enable OFED SRP (openibd) to autostart? [y]: n

Additional instructions for using SRP are described in 

.

9.

Once the install has completed, quit the installer by typing x until you have 
exited. 

10. Reboot the machine.

If you want support for 32-bit programs, you can install the 32-bit libraries on 
a 64-bit system by typing:
# ./INSTALL --32bit
