Aries Binary Translator
Aries is the HP-UX PA-RISC to HP-UX Itanium binary emulator. Aries transparently
emulates both 32-bit and 64-bit HP-UX PA-RISC applications on HP-UX 11i v2.
The Aries distribution on HP-UX Itanium-based systems consists of four shared
libraries:
/usr/lib/hpux32/aries32.so
/usr/lib/hpux32/pa_boot32.so
/usr/lib/hpux64/aries64.so
/usr/lib/hpux64/pa_boot64.so
The HP-UX 11i v2 kernel invokes pa_boot[32/64].so when a 32/64-bit PA-RISC binary
is launched. Similarly, pa_boot[32/64].so invokes aries[32/64].so.
Summary of Change
Changes for Aries on HP-UX 11i v2 include the following:
• Support for MxN threads
• Support for Itanium 2 processor
• Experimental implementation of a new dynamic translator with improved
performance
By default, the current dynamic translator is turned on and the experimental
dynamic translator is turned off. To use the experimental dynamic translator, you
will need to add an option to the Aries resource file. More details about this option,
and about other changes to Aries, can be found in the manpage, Aries (5).
