Binary Compatibility Across Hardware Platforms
HP maintains application binary compatibility across all hardware platforms of the
same family which are supported by the same version of HP-UX. This binary
compatibility requires that application software uses only externally documented and
supported software interfaces. In other words, binary compatibility across the members
of a hardware family (such as PA-RISC) is provided if the following conditions apply:
• The hardware platforms are members of the same family, e.g., they are all
PA-RISC-based.
• The hardware platforms are both running the same version of HP-UX.
• The application has used only externally documented and supported software
interfaces (e.g., does not use undocumented interfaces).
• The application software has no dependencies on specific types of hardware (e.g.,
specific mass storage devices or specific I/O or networking adapters).
HP has an excellent record of introducing new processors that provide complete software
binary compatibility with previous processors, thus protecting customer and partner
investments and allowing support for new processors with a minimum of risk and
investment. HP has always recognized that software binary compatibility with new
processors is an important partner and customer requirement.
PA-8800/PA-8900 Binary Compatibility
Applications and software developed for systems with the earlier generation PA 8x00
processors will run correctly and without modification on the PA-8800 and PA-8900
processors. These new processors differ from previous ones by providing two cores within
a single processor (dual-core).
