Re: 32bit HP-UX for Itanium?
Itanium (ia64) can only run 64bit OS which is 11.23/11.31.
Check this link:

Re: 32bit HP-UX for Itanium?
ARIES allows 32-bit and 64-bit PA-RISC code to run on the Itanium architecture.
If you are concerned about performance penalties running PA-RISC code under Aries, recompile it for the Itanium platform if you can.

Re: 32bit HP-UX for Itanium?
I understand it can only run a 64 bit OS but can you run a 32 bit application under Itanium under that 64 bit OS (in native mode and not under ARIES)? For instance, under HP-UX PA-RISC, the OS is 64 bit but you can run either a 64 bit application or a 32 bit application under that OS with no problems.
thx in advance

Re: 32bit HP-UX for Itanium?
So your don't need any emulator to run the 32bit apps? Is this documented somewhere?
I have read that Intel removed the hardware base 32bit capability from the Itanium chip, starting with Montecito.

Re: 32bit HP-UX for Itanium?
Aries comes free on all Itanium machine.
As said in the above thread, the time you invoke the 32/64bit PA programs, IPF Kernel recognizes a PA-RISC HP-UX executable and invokes Aries to emulate the application.
Check the man page (5) aries for details.
Cheers!!

Re: 32bit HP-UX for Itanium?
As I mention in my earlier post, I asked if the 32bit apps can run native and not via ARIES.
So my conclusion is that Itanium cannot run 32bit application natively and must use the ARIES emulator. Is this correct?
Thx

Re: 32bit HP-UX for Itanium?
No, HP-UX doesn't run x86 binaries (on Itanium or anything else). But there are 32-bit *Itanium* binaries. HP-UX will run those just fine, just like 32-bit PA binaries are generated and run on PA. (In fact, the default compilation mode is DD32 (32-bit) on both, if I recall correctly).

Re: 32bit HP-UX for Itanium?
This now makes sense. I guess the worst case is that the apps needs to be recompiled on the Itanium server.
