NAME
PAPI_get_multiplex - Get the multiplexing status of specified event set. SYNOPSIS
Detailed Description C Interface: #include <papi.h> int PAPI_get_multiplex( int EventSet ); Fortran Interface: #include fpapi.h PAPIF_get_multiplex( C_INT EventSet, C_INT check ) Parameters: EventSet an integer handle for a PAPI event set as created by PAPI_create_eventset Return values: PAPI_OK PAPI_EINVAL One or more of the arguments is invalid, or the EventSet is already multiplexed. PAPI_ENOEVST The EventSet specified does not exist. PAPI_EISRUN The EventSet is currently counting events. PAPI_ENOMEM Insufficient memory to complete the operation. PAPI_get_multiplex tests the state of the PAPI_MULTIPLEXING flag in the specified event set, returning TRUE if a PAPI event set is multiplexed, or FALSE if not. Example: * int EventSet = PAPI_NULL; * int ret; * * // Create an empty EventSet * ret = PAPI_create_eventset(&EventSet); * if (ret != PAPI_OK) handle_error(ret); * * // Bind it to the CPU component * ret = PAPI_assign_eventset_component(EventSet, 0); * if (ret != PAPI_OK) handle_error(ret); * * // Check current multiplex status * ret = PAPI_get_multiplex(EventSet); * if (ret == TRUE) printf("This event set is ready for multiplexing.") * if (ret == FALSE) printf("This event set is not enabled for multiplexing.") * if (ret < 0) handle_error(ret); * * // Turn on multiplexing * ret = PAPI_set_multiplex(EventSet); * if ((ret == PAPI_EINVAL) && (PAPI_get_multiplex(EventSet) == TRUE)) * printf("This event set already has multiplexing enabled0); * else if (ret != PAPI_OK) handle_error(ret); * See Also: PAPI_multiplex_init PAPI_set_opt PAPI_create_eventset Author Generated automatically by Doxygen for PAPI from the source code.

NAME
PAPI_stop - Stop counting hardware events in an event set. SYNOPSIS
Detailed Description C Interface: #include <papi.h> int PAPI_stop( int EventSet, long long * values ); Parameters: EventSet -- an integer handle for a PAPI event set as created by PAPI_create_eventset values -- an array to hold the counter values of the counting events Return values: PAPI_OK PAPI_EINVAL One or more of the arguments is invalid. PAPI_ESYS A system or C library call failed inside PAPI, see the errno variable. PAPI_ENOEVST The EventSet specified does not exist. PAPI_ENOTRUN The EventSet is currently not running. PAPI_stop halts the counting of a previously defined event set and the counter values contained in that EventSet are copied into the values array Assumes an initialized PAPI library and a properly added event set. Example: * int EventSet = PAPI_NULL; * long long values[2]; * int ret; * * ret = PAPI_create_eventset(&EventSet); * if (ret != PAPI_OK) handle_error(ret); * * // Add Total Instructions Executed to our EventSet * ret = PAPI_add_event(EventSet, PAPI_TOT_INS); * if (ret != PAPI_OK) handle_error(ret); * * // Start counting * ret = PAPI_start(EventSet); * if (ret != PAPI_OK) handle_error(ret); * poorly_tuned_function(); * ret = PAPI_stop(EventSet, values); * if (ret != PAPI_OK) handle_error(ret); * printf("%lld ",values[0]); * See Also: PAPI_create_eventset PAPI_start Author Generated automatically by Doxygen for PAPI from the source code.
