Enabling quadrant 3 for 32 bit IPF binary

[Anupam Anshu_1]

How do we enable quadrant 3 for a 32 bit binary on IPF.

chatr +q3p doesn't work on IPF.

From some documets we found that:

1. The binary should be complied with -N option.
2. Then "chatr +as " should be used to enable quadrant 3.

But after compiling with -N option, I am not able to execute the binary at all.

From aCC manpage:
------------------------------------
-N Cause the output file from the linker to be marked as
unshareable. For details and system defaults, see
ld(1).
------------------------------------

Is the binary becoming unshareable as the manpage of aCC suggests?

It would be really great if you could let us know "How to enable quadrant 3 for 32 bit IPF binary".

Thanks and regards,

Anshu

PS: Basically I am looking for "chatr +q3p " on IPF.

Try this when you compile:

cc -Ae -Wl,-N -o mallocmax mallocmax.c
chatr +q3p enable mallocmax

and your executable should work OK. However, there is another add ress model(I am assuming you're running 11.23) called MPAS which gives you access to all the 32bit quadrants and allows as much as 3800 megs for local storage:

cc -Ae -Wl,+as,mpas -o mallocmax mallocmax.c

That program will also work quite well for maximum RAM usage in the limited 32bit model. Note that maxdsiz will have to be 3900megs (and maxdsiz_64 larger than maxdsiz).

Of course, if you are running into 32-bit limits, it might be a very good time to start working on a 64-bit migration. There are various tools and options to the compiler available to you to get started on that...

I believe the following solves the issue:

aCC -Ae -N -Wl,+as,mpas -o mallocmax mallocmax.C

Thanks a lot for your help.
