cpusetSetMemList(3x)cpusetSetMemList(3x)NAMEcpusetSetMemList - set the list of all nodes with memory assigned to a
cpuset
SYNOPSIS
#include <cpuset.h>
int cpusetSetMemList(cpuset_QueueDef_t *qdef, int count,
cnodeid_t *mem;
DESCRIPTION
The cpusetSetMemList function is used to set the list of the nodes with
memory that will be assigned to a cpuset. The list of nodes IDs will be
copied into memory reference by the qdef argument, which must be
allocated by the cpusetAllocQueueDef(3x) function. For additional
information on the cpuset_QueueDef_t type, consult the
cpusetAllocQueueDef(3x) man page.
The count argument is the number of node IDs in the list. The list
argument references the memory array that holds the list of node IDs
whose memory will be included in the cpuset.
This list of nodes will then be used when the cpuset is created, using
the cpusetCreate(3x) function, to determine what memory to include in the
cpuset.
EXAMPLES
This example sets the list of nodes with memory assigned to the cpuset
mpi_set.
cpuset_QueueDef_t *qdef = NULL;
int count = 4;
cnodeid_t mems[] = {2,3,4,5}
/* Create qdef struct for 4 CPUs */
qdef = cpusetAllocQueueDef(4);
/* Set the list of memory nodes */
if ( !cpusetSetMemList(qdef, count, mems)) ) {
perror("cpusetSetMemList");
exit(1);
}
/* After setting other cpuset queue attributes */
/* Create the cpuset */
if ( !cpusetCreate("mpi_set", qdef) ) {
perror("cpusetCreate");
exit(1);
}

DIAGNOSTICS
If successful, cpusetSetMemList returns 1. If cpusetSetMemList fails, it
returns 0 and errno is set to indicate the error.
