PAPI_get_hardware_info Class Reference

get information about the system hardware More...

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_EINVALOne or more of the arguments is invalid.
Bug:
If called before initialization the behavior of the routine is undefined.
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;
exit(1);
if ((hwinfo = PAPI_get_hardware_info()) == NULL)
exit(1);
printf("%d CPUs at %f Mhz.\en",hwinfo->totalcpus,hwinfo->mhz);
