Re: Why stack is so big under HP IA 64!
procsize is not an hpux provided tool. The version I have is PA-RISC and does nto run directly on my Itanium to try.

Re: Why stack is so big under HP IA 64!
Hence if you look solely at the virtual size of the stack, you will see it at maxssiz or maxssiz_64bit depending if the process is 32 or 64-bit (and what the value was at the time of the process starting if you've changed it). If procsize has an option to private RES (physical memory consumption) you should see much more variety in stack consumption (and for simply programs probably only 1 to 4 pages).
You could make it lower by lowering maxssiz... but unless you really need to, there's very little point.

1) The normal stack, maxssiz
2) The RSE stack, maxrsessiz
3) Thread stacks, which are smaller copies of 1) & 2).
>Don: You could make it lower by lowering maxssiz but unless you really need to, there's very little point.
One reason not to have large maxssiz is that if your maxdsiz is >= 1 Gb, every byte in maxssiz reduces maxdsiz.

Re: Why stack is so big under HP IA 64!
-V Display the virtual set size info (default)
-R Display the Resident set size info
The default is -V, so the displayed stack may not true. It that correct?
Besides, is there any tools can be used to make memory cosum between different paltforms? Such as Linux, HP, Solaris and so on.

It seems this will give how much is actually used.
>is there any tools can be used to make memory cosum between different platforms?
To show memory consumption? They are probably all different. There is glance.
