Benchmark written in TBB

[irisshinra308]

Hi~

I am new to Intel TBB and trying to make some modification to it.

However, I am wondering if there are some benchmarks or applications which are written in TBB.

Any help would be grateful

Thanks for reading

In open-source source distribution you can find some benchmarks and tests in folders:

src/test/

src/perf/

Although, they are synthetic tests, not full-fledged applications.

Hi,

Can you explain, please, how I can compile and run src/perf content?

And do you know, if is some there standard benchmark, which test ability of processor to run different number of threads? I need some kind of time = time(NumberOfThreads) distribution.

Thanks in advice,

Igor.

Please try gmake time_{testname} [args={test arguments}] from src/ directory. E.g. "gmake time_hash_map_fill args=1:16"
Each test has its own command line specifics and usage model but number of threads usually passed in "min:max" form.

Also, you can try the PARSEC benchmark suite for your analysis. You can run the serial/pthreads/openmp versions of the packages as well to compare your results.

The benchmark is supposed to compare two or more implementstions on the same dataset and operations. But TBB comes with only one implementation of the hash table (still). Check the configuration in the first lines of the time_hash_map_fill.cpp, BOX2 defines the second implementation which is not available by default. E.g. you could use concurrent_hash_map from TBB 2.1 to check the performance difference with new algorithm in 2.2.
