encrypted itself. As a result, enterprises need platforms that can encrypt and decrypt data very quickly. The x455 is suited to this task. To compare the performance in integer and floating-point operations with other processors on the market, see SPECint_base2000 and SPECfp_base2000 benchmarks at: http://www.spec.org 2.7.4 In-house developed compute-intensive applications For developers, the 64-bit architecture allows creation of applications using a familiar programming model that encourages the development of a wide-ranging set of enterprise solutions. The experiences gained on the IA-32 platform can be reused when creating applications for Itanium 2-based systems. Thus developers are not required to start from scratch to make their transition to the 64-bit world. In most cases, existing 32-bit code will not require a complete rewrite, but only recompilation. This, however, should not be used as a long-term and easy option if re-writing will yield significant performance benefits. IA-64 parallelism is managed by the compiler itself. Application development does not require special techniques before it is compiled. Currently available compilers optimized for Itanium 2 include: Intel C++ Compiler Intel Fortran Compiler Microsoft SDK/C/C++ Compiler 2.7.5 Science and technology industries Science and technology industries (S&TC) require the processing of large and complex calculations to solve challenging problems. While S&TC industries are characterized by compute-intensive workloads that require special server characteristics to meet their performance needs, each industry, such as aerospace, automotive petroleum, research, or weather, also has its own set of S&TC applications, each demanding different computing solutions. The Itanium 2-based systems are an ideal platform for compute-intensive applications. It is for this reason that the Itanium and Itanium 2 processors were chosen for the largest American-built supercomputer, the TeraGrid project sponsored by the National Center for Supercomputing Applications. When finally deployed with more than 3,000 Itanium 2 chips, TeraGrid will be capable of more than 14 billion floating-point operations per second (teraflops). Chapter 2. Positioning 51

In-house developed compute-intensive applications

For developers, the 64-bit architecture allows creation of applications using a

familiar programming model that encourages the development of a wide-ranging

set of enterprise solutions. The experiences gained on the IA-32 platform can be

reused when creating applications for Itanium 2-based systems. Thus developers

are not required to start from scratch to make their transition to the 64-bit world.

In most cases, existing 32-bit code will not require a complete rewrite, but only

recompilation. This, however, should not be used as a long-term and easy option

if re-writing will yield significant performance benefits.

IA-64 parallelism is managed by the compiler itself. Application development

does not require special techniques before it is compiled. Currently available

compilers optimized for Itanium 2 include:

Intel C++ Compiler

Intel Fortran Compiler

Microsoft SDK/C/C++ Compiler

Science and technology industries

Science and technology industries (S&TC) require the processing of large and

complex calculations to solve challenging problems.

While S&TC industries are characterized by compute-intensive workloads that

require special server characteristics to meet their performance needs, each

industry, such as aerospace, automotive petroleum, research, or weather, also

has its own set of S&TC applications, each demanding different computing

solutions.

The Itanium 2-based systems are an ideal platform for compute-intensive

applications. It is for this reason that the Itanium and Itanium 2 processors were

chosen for the largest American-built supercomputer, the TeraGrid project

sponsored by the National Center for Supercomputing Applications. When finally

deployed with more than 3,000 Itanium 2 chips, TeraGrid will be capable of more

than 14 billion floating-point operations per second (teraflops).
