Although QLogic recommends that all RPMs are installed on all nodes, some are 
optional depending on which type of node is being used. To see which RPMs are 
required or optional for each type of node, according to its function as a compute 
node, front end node, development machine, or Subnet Manager (SM), see 

 “

”. 

„

Installing all the RPMs (except for OpenSM) on all nodes is easiest.

„

If you do not plan to run all of the available programs, you can install a 
subset of the RPMs. See 

.

„

Install the 

OpenSM

 RPM only if you do not plan to use a switch-based or 

host-based SM. The 

OpenSM

 RPM is normally installed on the node on which 

it will be used. If installed, it is on by default. This behavior can be modified. 
See 

 for more information.

„

Install the infinipath RPM on the all nodes where you install the 
mpi-frontend RPM.

Use InfiniPath, QLogic MPI, and basic 
OpenFabrics protocols such as IPoIB 
and SRP

The RPM sets in the InfiniPath* and 
InfiniPath-MPI directories

Run OpenFabrics programs that use the 
IB verbs interfaces, such as diagnostics, 
benchmarks, verbs-based MPI, VNIC, 
and SDP sockets

The RPM sets in the InfiniPath* and the 
OpenFabrics* directories

Use all of the above programs

The RPM sets in the InfiniPath*, 
InfiniPath-MPI, and the OpenFab-
rics* directories

Add OpenSM as a your subnet manager The RPM sets in the OpenFabrics and 

OpenSM directories. (OpenSM has depen-

dencies on OpenFabrics.)

Use other MPIs (MVAPICH and Open 
MPI) that have been compiled with Path-
Scale, GNU, PGI, and Intel compilers. 
Includes test files.

Use other HCAs with OpenFabrics
