PAPIf_hl_region_end

Reads and stores hardware events at the end of an instrumented code region.

Fortran Prototype:

#include 'fpapi.h'
PAPIf_hl_region_end( 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.

PAPIf_hl_region_end reads hardware events and stores the difference to the values from PAPIf_hl_region_begin at the end of an instrumented code region. Assumes that PAPIf_hl_region_begin was called before. Note that an output is automatically generated when your application terminates.

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_region_end("computation", retval)
if ( retval .NE. PAPI_OK ) then
    write (*,*) "PAPIf_hl_region_end failed!"
end if
