PAPIf_hl_region_end Class Reference
PAPI Fortran High Level API

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

Detailed Description

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
write
ssize_t write(int fd, const void *buf, size_t count)
