NAME¶
PAPIf_hl_read -
Reads and stores hardware events inside of an instrumented code region.
SYNOPSIS¶
Detailed Description¶
Fortran Prototype:
#include <fpapi.h>
int PAPIf_hl_read( C_STRING region, C_INT check )
int PAPIf_hl_read( C_STRING region, C_INT check )
Parameters:
region -- a unique region name corresponding to
PAPIf_hl_region_begin
Return values:
PAPI_OK
PAPI_ENOTRUN -- EventSet is currently not running or could not determined.
PAPI_ESYS -- A system or C library call failed inside PAPI, see the errno variable.
PAPI_EMISC -- PAPI has been deactivated due to previous erros.
PAPI_ENOMEM -- Insufficient memory.
PAPI_ENOTRUN -- EventSet is currently not running or could not determined.
PAPI_ESYS -- A system or C library call failed inside PAPI, see the errno variable.
PAPI_EMISC -- PAPI has been deactivated due to previous erros.
PAPI_ENOMEM -- Insufficient memory.
PAPIf_hl_read reads hardware events and stores them internally inside of an instrumented code region. Assumes that PAPIf_hl_region_begin was called before.
Example:
* integer retval * * call PAPIf_hl_region_begin("computation", retval) * if ( retval .NE. PAPI_OK ) then * write (*,*) "PAPIf_hl_region_begin failed!" * end if * * !do some computation here * * call PAPIf_hl_read("computation", retval) * if ( retval .NE. PAPI_OK ) then * write (*,*) "PAPIf_hl_read failed!" * end if * * !do some computation here * * call PAPIf_hl_region_end("computation", retval) * if ( retval .NE. PAPI_OK ) then * write (*,*) "PAPIf_hl_region_end failed!" * end if * *
