]]>maxdsiz, maxdsiz_64bit - maximum size (in bytes) of the data segment for any user process
maxssiz, maxssiz_64bit - maximum size (in bytes) of the stack for any user process
maxrsessiz, maxrsessiz_64bit - maximum size (in bytes) of the RSE stack for any user process
filecache_max - maximum quantity of memory to utilize for filesystem buffer cache
filecache_min - minimum quantity of memory to utilize for filesystem buffer cache
fcache_fb_policy - sets policy for flushing filesystem buffer cache data to disk
base_pagesize - sets the base page size in KBytes
pagezero_daemon_enabled - enables/disables background zeroing of large pages
vxfs_ifree_timelag - sets the inode minimum existence time for VxFS filesystems
lcpu_attr - toggles the OS's use of hardware threads of cores in the default processor set
numa_policy - informs the kernel the order and priority by which cell-local vs global interleaved memory should be used on NUMA systems
HP-UX System Utilities
mpsched - binds processes to cpus or nodes
setboot - display and modify boot variables in stable storage
kctune - display and modify kernel tunable parameters
System Configuration Commands:
cpuconfig - EFI command to enable or disable a processor prior to booting. Also used to enable/disable hardware threading at the firmware level
Additional Notes on partitions and local memory:
The HP Integrity rx7640, rx8640, and Superdome systems
may be configured as one large system or as multiple independent smaller systems via hard parititions
(nPars). Each hard partition consists of one or more cells with their associated processors, memory,
and I/O chassis, and is isolated from events in other partitions. The memory within a partition can
either be assigned to local memory pools for each cell, or to an interleaved pool that is
distributed by cache line across the cells. Partitions and their attributes can be created and
modified via the support management station, or via the nPartition (par*) commands running on an
os instance in a system partition.
The default model is blended.
