After the packages have been removed, continue with the InfiniPath installation.

You can also use the 

--prefix 

option with the 

rpm

 command to relocate the 

install directory of any packages that you need to move. See 

 for more information.

On RHEL 4 distributions, libgfortran must be installed before installing the 

QLogic openmpi_gcc* RPM; otherwise, the installation will fail. The 
libgfortran* RPM is available as part of the RHEL 4 distribution. 

On a 64-bit system, 32-bit 

glibc

 must be installed before installing the 

mpi-frontend-* RPM. 

mpirun

, which is part of the mpi-frontend-* RPM, 

and requires 32-bit support.

If 32-bit glibc is not installed on a 64-bit system, an error like this displays when 

installing mpi-frontend:

# rpm -Uv ~/tmp/mpi-frontend-2.3-14729.802_rhel4_qlc.i386.rpm 
error: Failed dependencies:
/lib/libc.so.6 is needed by mpi-frontend-2.3 
-14729.802_rhel4_qlc.i386

In older distributions, such as RHEL4, the 32-bit glibc is contained in the 
libgcc

 RPM. The RPM name will be similar to this:

libgcc-<version>.EL4.i386.rpm

In newer distributions, glibc is an RPM name. The 32-bit glibc is named 

similarly to:

glibc-<version>.i686.rpm OR
glibc-<version>.i386.rpm

Check your distribution for the exact RPM name.

During the first installation of InfiniPath software, /etc/initscript is created 

or modified to increase the amount of lockable memory (up to 128 MB) for normal 
users. This change will not take effect until the system is rebooted, and jobs may 
fail with error messages about locking memory or failing mmap. This error is 
described in the QLogic MPI Troubleshooting section “Lock Enough Memory on 
Nodes When Using a Batch Queuing System” in the QLogic Host Channel 
Adapter and QLogic OFED Software Users Guide.

This is not an issue when upgrading to a newer version of the InfiniPath software.
