Using Preload to boot startup and general performance for Fedora

Preload is a daemon that analyses what you do and fetches the binaries you're mostly likely to use to boost starup and general performance. To make a very superficial comparison, it is similar to Windows Superfetch

Note 1: To install preload on Fedora 11
# yum install preload

Note 2: To tweak the preload configuration, you can tweak the
# /etc/preload.conf
(the default value should work well for all most users)

Note 3: To view the log file of the preload daemon
# less /var/log/preload.log

Note 4: If you wish to take a look on what Preload is caching for you, you go to
# /var/lib/preload/preload.state

Note 5: To ensure that the preload daemon is startup everytime
# chkconfig --level 35 preload on

OpenMPI, CentOS Linking Error - libmpi.so.0 :cannot open shared object file: No such file or directory

I was installing OpenMPI on CentOS 5.x. After installation, I  tried to  use pirun, I encountered this error
libmpi.so.0 :cannot open shared object file: No such file or directory

The reason for the error is that the the loader is not able to find the libmpi.so because /usr/local/lib is not in its PATH

To resolve the issues, you have to do the following
# vim /etc/ld.so.conf
(Add the /usr/local/lib into the file)
# ldconfig
