IA-32 applications
SuSE SLES 8 proved the IA-32 runtime environment installed by default. This
environment contains glibc, ncurses, C++ and X11 libraries to guarantee
compatibility with IA-32 applications.
If you want to compile any application from code source to IA-32 platform, it is
still possible, and you may also compile it to IA-64. This will offer you the
possibility to still use older IA-32 applications, if you don’t have the source code
or you don’t want to recompile it to IA-64.

Information about the installed system
Our recently installed Linux system can offer us some information about the
x450, such as CPU details, memory, and some other useful information. The
following sections outline what the Linux kernel found about the CPU used during
our tests. We used the /proc file system to obtain this information.
CPU information
Linux recognizes the x450’s processors as an Itanium 2, from the IA-64
architecture. During our tests we only had one single CPU, and it was identified
by the system as the CPU number 0. On multiprocessor systems, we will find all
the information regarding every CPU.
