PAPI_get_hardware_info — get information about the system hardware

Detailed Description

In C, this function returns a pointer to a structure containing information about the hardware on which the program runs. In Fortran, the values of the structure are returned explicitly.

Return values:

PAPI_EINVAL One or more of the arguments is invalid.

Note:

The C structure contains detailed information about cache and TLB sizes. This information is not available from Fortran.

Examples:

const PAPI_hw_info_t *hwinfo = NULL;
if (PAPI_library_init(PAPI_VER_CURRENT) != PAPI_VER_CURRENT)    
exit(1);
if ((hwinfo = PAPI_get_hardware_info()) == NULL)
exit(1);
printf("%d CPUs at %f Mhz.\n",hwinfo->totalcpus,hwinfo->mhz);
