KMALLOC_NODE(9) Memory Management in Linux KMALLOC_NODE(9)NAME
kmalloc_node - allocate memory from a specific node
SYNOPSIS
void * kmalloc_node(size_t size, gfp_t flags, int node);
ARGUMENTS
size
how many bytes of memory are required.
flags
the type of memory to allocate (see kcalloc).
node
node to allocate from.
DESCRIPTION
kmalloc for non-local nodes, used to allocate from a specific node if available. Equivalent to kmalloc in the non-NUMA single-node case.

numastat - Print statistics about NUMA memory allocation
SYNOPSIS
numastat
DESCRIPTION
numastat displays NUMA allocations statistics from the kernel memory allocator. Each process has NUMA policies that specifies on which
node pages are allocated. See set_mempolicy(2) or numactl(8) on details of the available policies. The numastat counters keep track on
what nodes memory is finally allocated.
The counters are separated for each node. Each count event is the allocation of a page of memory.
numa_hit is the number of allocations where an allocation was intended for that node and succeeded there.
numa_miss shows how often an allocation was intended for this node, but ended up on another node due to low memory.
numa_foreign is the number of allocations that were intended for another node, but ended up on this node. Each numa_foreign event has a
numa_miss on another node.
interleave_hit is the number of interleave policy allocations that were intended for a specific node and succeeded there.
local_node is incremented when a process running on the node allocated memory on the same node.
other_node is incremented when a process running on another node allocated memory on that node.
SEE ALSO numactl(8)set_mempolicy(2)numa(3)NOTES
numastat output is only available on NUMA systems.
numastat assumes the output terminal has a width of 80 characters and tries to format the output accordingly.
EXAMPLES
watch -n1 numastat
watch -n1 --differences=accumulative numastat
FILES
/sys/devices/system/node/node*/numastat
BUGS
The output formatting on machines with a large number of nodes could be improved.

I want to create a new user and grant him ONLY transfer files access to a specific directory where he can only upload and read the files. He should be restricted to this activity only.

I am testing the behavior of a 32 bit application running on Solaris 5.10 (SPARC), and realize it reaches 4GB of memory and then crashes.
