Memory Space Parameter Summary
See also “Memory Allocation Management” on page 51.
ProcessMgmt:
CPU
timeslice Maximum time a process can use the CPU until it is made
available to the next process having the same process
execution priority. This feature also prevents runaway
processes from causing system lock-up. Manpage: timeslice
(5).
ProcessMgmt:
Memory
maxdsiz Maximum process data storage segment space that can be
used for statics and strings, as well as dynamic data space
allocated by sbrk() and malloc() (32-bit processes).
Manpage: maxdsiz (5).
ProcessMgmt:
Memory
maxdsiz_64bit Maximum process data storage segment space that can be
used for statics and strings, as well as dynamic data space
allocated by sbrk() and malloc() (64-bit processes).
Manpage: maxdsiz (5).
ProcessMgmt:
Memory
maxrsessiz Maximum size (in bytes) of the RSE stack for any user
process on the IPF platform. Manpage: maxrsessiz (5).
ProcessMgmt:
Memory
maxrsessiz_64bit Maximum size (in bytes) of the RSE stack for any user
process on the IPF platform. Manpage: maxrsessiz (5).
ProcessMgmt:
Memory
maxssiz Maximum dynamic storage segment (DSS) space used for
stack space (32-bit processes). Manpage: maxssiz (5).
ProcessMgmt:
Memory
maxssiz_64bit Maximum dynamic storage segment (DSS) space used for
stack space (64-bit processes). Manpage: maxssiz (5).
ProcessMgmt:
Memory
maxtsiz Maximum allowable process text segment size, used by
unchanging executable-code (32-bit processes). Manpage:
maxtsiz (5).
ProcessMgmt:
Memory
maxtsiz_64bit Maximum allowable process text segment size, used by
unchanging executable-code (64-bit processes). Manpage:
maxtsiz (5).
ProcessMgmt:
Memory
pa_maxssiz_32bit Maximum size (in bytes) of the stack for a user process
running under the PA-RISC emulator on IPF. Manpage:
pa_maxssiz (5).
