NAME

PAPI_set_domain - Set the default counting domain for new event sets bound to the cpu component.

SYNOPSIS

Detailed Description

C Prototype:

#include <papi.h>
int PAPI_set_domain( int domain );

Parameters

domain one of the following constants as defined in the papi.h header file

PAPI_DOM_USER User context counted
PAPI_DOM_KERNEL Kernel/OS context counted
PAPI_DOM_OTHER Exception/transient mode counted
PAPI_DOM_SUPERVISOR Supervisor/hypervisor context counted
PAPI_DOM_ALL All above contexts counted
PAPI_DOM_MIN The smallest available context
PAPI_DOM_MAX The largest available context

Return values

PAPI_OK
PAPI_EINVAL One or more of the arguments is invalid.

PAPI_set_domain sets the default counting domain for all new event sets created by PAPI_create_eventset in all threads. This call implicitly sets the domain for the cpu component (component 0) and is included to preserve backward compatibility.

Example:

int ret;
// Initialize the library
ret = PAPI_library_init(PAPI_VER_CURRENT);
if (ret > 0 && ret != PAPI_VER_CURRENT) {
  fprintf(stderr,"PAPI library version mismatch!\n");
  exit(1); 
}
if (ret < 0) handle_error(ret);
// Set the default domain for the cpu component
ret = PAPI_set_domain(PAPI_DOM_KERNEL);
if (ret != PAPI_OK) handle_error(ret);
ret = PAPI_create_eventset(&EventSet);
if (ret != PAPI_OK) handle_error(ret);
