Alternatively, if the following line is specified, the stack size of 32 MB will be applied to all 32-bit PA-RISC
applications invoked by the user or by all users depending on ARIES RC file being placed in user’s home
directory or in the root directory.

Sample ARIES resource configuration files are shown below. You can modify them to suit your require-
ments.

ARIES MEMORY MANAGEMENT
ARIES Managed Area (AMA)
ARIES consumes a small amount of memory (called ARIES Managed AREA (AMA)) towards the end of the
PA-RISC application’s private data segment. AMA is reserved exclusively for ARIES use by the Integrity
HP-UX operating system. The AMA size is decided by these kernel tunable parameters:
• pa_maxssiz_32bit for 32-bit ARIES
• pa_maxssiz_64bit for 64-bit ARIES
See pa_maxssiz(5) for more details.
The Integrity HP-UX OS passes a pointer
load_info to a structure of type load_info_t defined in
/usr/include/crt0.h
, to ARIES. The start and end of AMA are marked by
load_info->li_priv_mmf_start
and load_info->li_bstore_start respectively. ARIES
uses AMA to store following data:
1. ARIES’s initialized data, un-initialized data (BSS) and thread local storage (TLS).
2. ARIES heap for internal
malloc() calls and for creating ARIES threads for emulation of PA-RISC
application’s threads.
3. PA-RISC application’s stack.
4. Translated code buffer (code cache region).
5. Data structures to access and manage the translated code blocks.
6. AMAP data structures for mapping of PA-RISC basic blocks and translated code block addresses.
7. Memory area used by ARIES dynamic translator as heap.
Memory allocation from AMA happens dynamically on demand. A PA-RISC process running under ARIES
will have larger memory footprint (resident memory) as compared to native PA-RISC system. The increase
in process resident memory size depends on actual memory allocated from AMA.
