PAPI_set_cmp_domain - Set the default counting domain for new event sets bound to the specified component. SYNOPSIS
Detailed Description @par C Prototype: int PAPI_set_cmp_domain( int domain, int cidx ); @param domain one of the following constants as defined in the papi.h header file @arg PAPI_DOM_USER User context counted @arg PAPI_DOM_KERNEL Kernel/OS context counted @arg PAPI_DOM_OTHER Exception/transient mode counted @arg PAPI_DOM_SUPERVISOR Supervisor/hypervisor context counted @arg PAPI_DOM_ALL All above contexts counted @arg PAPI_DOM_MIN The smallest available context @arg PAPI_DOM_MAX The largest available context @arg PAPI_DOM_HWSPEC Something other than CPU like stuff. Individual components can decode low order bits for more meaning @param cidx An integer identifier for a component. By convention, component 0 is always the cpu component. Return values: PAPI_OK PAPI_EINVAL One or more of the arguments is invalid. PAPI_ENOCMP The argument cidx is not a valid component. PAPI_set_cmp_domain sets the default counting domain for all new event sets in all threads, and requires an explicit component argument. Event sets that are already in existence are not affected. To change the domain of an existing event set, please see PAPI_set_opt. The reader should note that the domain of an event set affects only the mode in which the counter continues to run. Counts are still aggregated for the current process, and not for any other processes in the system. Thus when requesting PAPI_DOM_KERNEL , the user is asking for events that occur on behalf of the process, inside the kernel. 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!0); exit(1); } if (ret < 0) handle_error(ret); // Set the default domain for the cpu component ret = PAPI_set_cmp_domain(PAPI_DOM_KERNEL,0); if (ret != PAPI_OK) handle_error(ret); ret = PAPI_create_eventset(&EventSet); if (ret != PAPI_OK) handle_error(ret); * See Also: PAPI_set_domain PAPI_set_granularity PAPI_set_opt PAPI_get_opt Author Generated automatically by Doxygen for PAPI from the source code.

PAPI_remove_events - Remove an array of hardware event codes from a PAPI event set. SYNOPSIS
Detailed Description A hardware event can be either a PAPI Preset or a native hardware event code. For a list of PAPI preset events, see PAPI_presets or run the papi_avail utility in the PAPI distribution. PAPI Presets can be passed to PAPI_query_event to see if they exist on the underlying architecture. For a list of native events available on current platform, run papi_native_avail in the PAPI distribution. It should be noted that PAPI_remove_events can partially succeed, exactly like PAPI_add_events. C Prototype: #include <papi.h> int PAPI_remove_events( int EventSet, int * EventCode, int number ); Parameters: EventSet an integer handle for a PAPI event set as created by PAPI_create_eventset *Events an array of defined events number an integer indicating the number of events in the array *EventCode Return values: Positive integer The number of consecutive elements that succeeded before the error. PAPI_EINVAL One or more of the arguments is invalid. PAPI_ENOEVST The EventSet specified does not exist. PAPI_EISRUN The EventSet is currently counting events. PAPI_ECNFLCT The underlying counter hardware can not count this event and other events in the EventSet simultaneously. PAPI_ENOEVNT The PAPI preset is not available on the underlying hardware. Example: int EventSet = PAPI_NULL; int Events[] = {PAPI_TOT_INS, PAPI_FP_OPS}; int ret; // Create an empty EventSet ret = PAPI_create_eventset(&EventSet); if (ret != PAPI_OK) handle_error(ret); // Add two events to our EventSet ret = PAPI_add_events(EventSet, Events, 2); if (ret != PAPI_OK) handle_error(ret); // Start counting ret = PAPI_start(EventSet); if (ret != PAPI_OK) handle_error(ret); // Stop counting, ignore values ret = PAPI_stop(EventSet, NULL); if (ret != PAPI_OK) handle_error(ret); // Remove event ret = PAPI_remove_events(EventSet, Events, 2); if (ret != PAPI_OK) handle_error(ret); * @see PAPI_cleanup_eventset PAPI_destroy_eventset PAPI_event_name_to_code PAPI_presets PAPI_add_event Author Generated automatically by Doxygen for PAPI from the source code.
