[parsec-users] General Question on Parsec

Hi Ramkumar,

 

It depends. There *are* differences between the versions at runtime.
Gilberto Contreras has written a paper on them, you can find it on the
PARSEC website. To what extent these differences will matter for your
experiments is hard to say. Another practical difference is that the
versions have different system dependencies, so in weird cases you might be
able to get one to run but not the other.

Hi Chris,

Looking at this site http://wiki.cs.princeton.edu/index.php/PARSEC it syas
that parsec benchmarks can use either pthreads,open mp or intel tbb. Is
there a large difference in using pthreads runtime versus openmp to build
these apps in terms of the workload? At a broad level is there any specific
advantage in using either? 

Thanks
Ramkumar

Fahimeh,

You can find the file containing a function by using the command line tool
"grep" to search for occurrences of the function name. To get the hotspots
of x264 and freqmine you can use a profiling tool like "gprof". Both tools
are standard and should be available on all Unix machines. You can consult
the man pages or various tutorials on the Internet to find out more about
the usage of these programs.

Best,
Chris

Hello,

Would you please let me know the file name containing the following
functions:

1) raverseBVH_with_StandardMesh  (raytrace)
2) PARTICLE_VELOCITY_ATTRIBUTE (facesim )
3) deflate_slow  (dedup)
4) build_tree   (dedup)

And please let me know the main functions that takes most of the execution
time of x264 and freqmine.


Thanks in advance,
Fahimeh
