The Red Hat Enterprise Linux family has been designed to cover the full
spectrum of corporate operating environments in a simple and consistent
manner. The family is comprised of four products, two designed for server
systems, two designed for client systems. There is a high level of commonality
across the products, thereby ensuring that application support, user
environments, and management tools are consistent.
PHP is free. You can download the latest version at any time from http://www.php.net for no charge.
The syntax of PHP is based on other programming languages, primarily C and Perl. If you already know C or Perl, or a C-like language such as C++ or Java, you will be productive using PHP almost immediately.
PHP is available for many different operating systems. You can write PHP code on the free Unixlike operating systems such as Linux and FreeBSD, commercial Unix versions such as Solaris and IRIX, or on different versions of Microsoft Windows.

Generally speaking, direct assembly
coding can outperform the use of intrinsics. Nevertheless,
for fairness of comparison with algorithms coded in C,we
use the provided intrinsics.
Our experimental results use single precision 32-bit ﬂoat-
ing point values as the element data type, unless otherwise
mentioned. Since SSE and SSE2 registers are 128 bits, this
choice means that S = 4. Our Pentium4 machine runs at 1.8
GHz, has 1GB of Rambus RDRAM, and uses the RedHat
Linux 7.1 operating system. We use Intel's C++ compiler
with the highest optimization level.
