MPAS Attribute 2

gm200 — Fri, 13 Jan 2006 11:08:49 GMT

In relation with the previous message "MPAS Attributes" with 32bit executable compiled on PA-RISC, I have recived an answer about the possibility to use MPAS process attribute only for ITANIUM.
Do someone know if exists a similar walkaround on PA-RISC (without recompile the code)? It's stange the availability of that facility for ITANIUM and not for PA-RISC. There is a planned patch related to this argument for PA-RISC?

Thanks

Sorry, guess I wasn't clear enough in the other thread.

There is no workaround on PA-RISC. The problem is not a software problem per se -- the fundamental chip architecture is different [I really don't want to go into gory details, and for that matter I'm not sure exactly what I can say in a public forum so I'm going to err on the side of caution and say no more], MPAS doesn't have the underlying functionality it needs to work on PA.

If you need more shared address space for a PA RISC binary you're going to have to recompile to 64-bit. The only other thing you can do is put all of your processes which share objects into the same Memory Window, and manage your objects yourself very carefully so that you only have <=2.75Gb of shared address space consumption at any given moment [you'll have to handle object creation/attach failure for the times that you exceed the address space]. I would think that 64-bit recompilation would be a lot simpler than that.

As the other thread is still open, please respond in THAT thread rather than open another thread on the same subject

I cannot solve the problem
