* To compile a benchmark without any monitoring:
|
||
|
|
|
||
|
|
$> gcc -I utilities utilities/instrument.c linear-algebra/kernels/atax/atax.c
|
||
|
|
|
||
|
|
|
||
|
|
|
||
|
|
* To compile a benchmark with execution time reporting:
|
||
|
|
|
||
|
|
$> gcc -I utilities utilities/instrument.c linear-algebra/kernels/atax/atax.c -DPOLYBENCH_TIME
|
||
|
|
|
||
|
|
|
||
|
|
* Available options
|
||
|
|
|
||
|
|
They are all passed as macro definitions during compilation time. The
|
||
|
|
current list is:
|
||
|
|
- POLYBENCH_TIME: output execution time (gettimeofday) [default: off]
|
||
|
|
- POLYBENCH_NO_FLUSH_CACHE: don't flush the cache before calling the
|
||
|
|
timer [default: flush the cache]
|
||
|
|
- POLYBENCH_LINUX_FIFO_SCHEDULER: use FIFO real-time scheduler for the
|
||
|
|
kernel execution, the program must be run as root, under linux only,
|
||
|
|
and compiled with -lc [default: off]
|
||
|
|
- POLYBENCH_CACHE_SIZE_KB: cache size to flush, in kB [default: 8192]
|
||
|
|
- POLYBENCH_TEST_MALLOC: use malloc instead of stack allocation [default: off]
|
||
|
|
- POLYBENCH_DUMP_ARRAYS: dump all live-out arrays on stderr [default: off]
|
||
|
|
|
||
|
|
- Nxx: override the default dataset values
|
||
|
|
|
||
|
|
|
||
|
|
* Collecting the execution time of all files
|
||
|
|
|
||
|
|
$> scripts/runall.sh <machine-name>
|
||
|
|
|
||
|
|
Note: the script runall must be run from the root directory of the archive.
|
||
|
|
|
||
|
|
|
||
|
|
** Specifying different dataset size for one file in particular
|
||
|
|
|
||
|
|
- Create a compiler.opts file under the directory of the benchmark
|
||
|
|
- Specify a set of options, e.g. -DX=1024 -DY=1024 (see gemm for an example)
|
||
|
|
|
||
|
|
|
||
|
|
** To specify another compiler
|
||
|
|
|
||
|
|
- Simplest is to edit scripts/runall.sh, and change the
|
||
|
|
COMPILER_COMMAND variable. One can also export the adequate
|
||
|
|
COMPILER_COMMAND variable in the shell environment.
