Itanium 2-based Platform Deployments - Solution
Stack Example

• Primary and performance sensitive apps
• Deploy native Itanium 2-based apps
• Examples Databases, CRM, ERP, business
  intelligence, technical computing
• IA-32 secondary applications
• Consider IA-32 Execution Layer
• Examples Database administration tools, system
  management, system monitoring, backup, recovery,
  custom applications which are not performance
  sensitive
• Considerations for running 32-bit applications on
  a 64-bit OS
• (Not specific to Itanium architecture)
• Applications containing 32-bit device drivers or
  16-bit apps are not supported
• Some older installers for 32-bit applications may
  not run

IA-32 Execution Layer (EL)

• IA-32 application support helps enable Itanium
  2-based deployments
• Allows Itanium 2-based solutions to be deployed
  when secondary applications in the stack have not
  yet ported to Itanium architecture
• IT managers converting from RISC can tap into the
  broad IA-32 ecosystem
• IA-32 EL is a new technology which supports IA-32
  applications running on Itanium 2-based systems
• IA-32 EL generally improves performance over the
  on-die hardware
• Performance will vary by application
• Deploy native Itanium architecture-based
  applications for optimal performance and
  capabilities run IA-32 secondary applications as
  needed
• Use Intel Xeon processors for world class
  32-bit enterprise performance

• Historically, support of IA-32 applications has
  been carried out by on-die hardware
• When using operating systems with IA-32 EL,
  support for IA-32 applications will be provided
  by IA-32 EL
• IA-32 EL will ship with leading operating systems
• Available 1/13 with Windows

IA-32 Execution Layer Performance

• 32-bit performance on Itanium 2-based systems is
  comparable to Xeon processor MP 1.5GHz
• Performance will vary by application
• Not all applications behave like SPECint
• IA-32 EL is expected to deliver 50 to 70 of
  native Itanium architecture performance over time

18
Platform Considerations

• Software
• Changes needed for any platform to support
  IA-32e mode
• 64-bit O/S
• 64-bit Drivers
• 64-bit capable BIOS
• Some applications may need to be recompiled to
  run correctly under Compatibility mode (no
  different from our competitions implementation)
• Compatibility mode does not support Virtual-8086
  Mode or Real Mode
• Applications which depend on these modes likely
  will not work in compatibility mode
• Certain O/S functions and/or APIs available in
  Legacy 32-bit mode, may not be supported in
  Compatibility mode
• Intel not aware of such instances, but it is
  possible
• SW developers need to work with O/S vendor to
  know for sure

19
Enabling Plans for Windows OSs

• 64-bit extension technology enabled with Windows
  Server 2003 Service Pack 1 (SP1)
