on faster Intel Itanium processors released in the future. The IEL is expected to supersede the Intel Value Engine
hardware feature since it will clearly provide much better performance on 32-bit applications.
Running RISC applications
Users can run their PA-RISC binaries unchanged and completely transparently, thanks to the Aries dynamic code
translator that is part of HP-UX 11i. This translator allows running 32-bit and 64-bit PA-RISC applications on the
Intel Itanium 2 microarchitecture without the need to recompile. A straightforward recompile of 32-bit and 64-bit
PA-RISC applications yields native Intel Itanium 2 processor binaries.
Porting and migration services: transition help from HP
Thousands of programs run quite well in Intel Itanium processor compatibility mode with minimal changes.
However, porting these applications to the Intel Itanium 2 processor allows them to run even better because they
can then take full advantage of the new processor’s distinctive capabilities.
To help customers make the transition to the Intel Itanium Processor Family and get the most from this exciting new
technology, HP offers a flexible set of services. Customers can select from the following:
• Porting and migration workshop
• Porting and migration guidance
• Porting and migration detailed assessment
• Porting and migration solution delivery
• Online services
See www.hp.com/products1/itanium/services/porting_migration.html
for all the details on these services.
Conclusion
On the road to becoming truly pervasive, the Intel Itanium 2 processor is faster and more capable than its
predecessor. Now, with the Integrity rx1600, rx2600, rx4640, and rx5670 servers, HP offers powerful servers
based on the Intel Itanium 2 processor and featuring the new HP zx1 Chipset. The Integrity rx1600 server utilizes
one or two Low Voltage Intel Itanium 2 processors and up to 16 GB of memory, the Integrity rx2600 server
utilizes one or two Intel Itanium 2 processors and up to 24 GB of memory, the Integrity rx4640 server can be
equipped with as many as 4 processors and as much as 64 GB of memory, and the Integrity rx5670 server
utilizes as many as 4 processors and as much as 96 GB of memory. These servers offer cutting-edge, 64-bit
power along with excellent price/performance.
The new servers are optimized for complex, floating-point-intensive computations, providing faster time to
solution for demanding applications. They are especially suited to SSL Web serving, and they offer significant
performance advantages over both IA-32- and RISC-based systems for Windows and database applications.
They’re also perfect for running SAP, Siebel, PeopleSoft, and SAS business application suites.
The Intel Itanium 2 processor’s ability to run IA-32 and RISC binaries without modification helps ensure protection
for previous software investments, and HP’s porting services can effect a complete transition that takes full
advantage of the Intel Itanium architecture. Another advantage is that customers with either of these servers can
run any of four industry-leading operating systems—HP-UX, Linux, Windows, or OpenVMS Evaluation Release
(until 2H 2004, when a production-quality release is expected). This multi-OS capability overcomes the
complexities and challenges associated with deploying and maintaining a heterogeneous operating environment.
Whether for technical computing or commercial IT, the HP Integrity rx1600, rx2600, rx4640, and rx5670 servers
offer superior power, scalability, and efficiency—with lower costs.
