[no]pa_os_cpu
[Disables] enables the emulation of the uname() and
sysconf() system calls, to return
information specific to native PA-RISC HP-UX systems. See uname(2) and sysconf(2).
Enable (
-pa_os_cpu ) this option flag only if the PA-RISC application expects the return
values of uname() and sysconf() system calls, to be specific to the values that would have
been obtained if the application was running on PA-RISC HP-UX system.
The default state of this option flag is disabled (
-nopa_os_cpu ).
-[no]sched_trace
[Disables] enables the trace scheduling and low level optimization of ARIES translated code.
NOTE: Enabling (-sched_trace ) this option flag may provide improved performance for
compute intensive applications.
The default state of this option flag is disabled (
-nosched_trace
).
-[no]trans
[Disables] enables the dynamic translation in ARIES. Disabling (
-notrans) this option flag is
useful only for triaging of dynamic translator failures.
WARNING: Disabling (
-notrans) this option flag will cause significant performance slow-
down.
The default state of this option flag is enabled (-trans).
-[no]unsafetrans
[Disables] enables the dynamic translation of self modifying (dynamically generated) code. Disa-
bling (-nounsafetrans
) this option flag is useful only for triaging of Java-based application
failures under ARIES.
WARNING: Disabling (
-nounsafetrans
) this option flag will cause significant performance
slowdown for Java-based applications.
The default state of this option flag is enabled (
-unsafetrans ).
-amapsz { size | default }
Size in kbytes of the total memory area to be used for ARIES address map (AMAP) data struc-
tures, for mappings between PA-RISC basic blocks and translated code addresses.
Value 32-bit ARIES 64-bit ARIES
Default: 16384 KB (16 MB) 24576 KB (24 MB)
Max: 65536 KB (64 MB) 98304 KB (96 MB)
Min: 8192 KB ( 8 MB) 8192 KB ( 8 MB)
NOTE: To minimize the performance drop due to increased frequency of ARIES AMAP area
overflow, HP recommends setting this option value at the default or maximum size.
For optimal performance, a ratio of 1:2:2 should be maintained for the values of the ARIES
options: -descsz, -amapsz, and -ccsz.
-amapsz_smc { size | default }
Size in kbytes of the memory area used for ARIES address map (AMAP) data structures
corresponding to dynamic translations of self modifying code of PA-RISC application. This area
is part of the memory region whose size is determined by the ARIES option -amapsz.
Value 32-bit ARIES 64-bit ARIES
Default: 2048 KB (2 MB) 2048 KB (2 MB)
Max: 4096 KB (4 MB) 4096 KB (4 MB)
Min: 512 KB 512 KB
-ap_heap_ssz { size | default }
Size in kbytes of the memory area used for the ARIES private heap. This area is part of the
ARIES heap whose size is determined by the ARIES option -heap_ssz . This area is used for
ARIES’s internal malloc() calls.
