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
