How to allocate MAX memory per process in HP-UX (PA-RISC) machine

[gireeshk7]

Hi All ,

How to set memory per process,

Because I am getting error like

[11] % ./test_mem.out

Total Memory Allocated to process so far: 1 MB

How much do you want?  The simplest way is to port to 64 bits then you can have up to maxdsiz_64bit.

Otherwise you can link with -N and get up to 2 Gb.

>data(kbytes)         3968588
>stack(kbytes)          262144

Your 32 bit limit is 3.9 Gb but you can only get that with -N and using chatr(1).

Your large maxssiz is also removing 262 Mb from that limit, you can reduce it to 100 Mb and get that back right away by setting a smaller value: ulimit -Ss 100000
