Parallelization Made Easier with Intel® Performance-Tuning Utility

CONCLUSION

The performance analysis features available in the Intel® Performance Tuning Utility assist at virtually every stage of both parallel and sequential software performance tuning and may be extremely helpful at the preliminary stages of determining parallelization strategies.

We discussed data-level decomposition strategy in real program examples and illustrated how the efficiency of a parallel implementation can be estimated, and which steps should be performed to optimize a parallel program using the Intel Performance Tuning Utility.

Being easy to use and powerful at the same time, Intel PTU is growing its customer base inside Intel for solving today's problems and serving as a vehicle for exploring new features for future commercial tools.

We plan on improving Intel PTU with newer performance data-collection techniques and analysis models to keep pace with user needs and modern processor architecture developments. Intel PTU is available for an external download from Whatif.intel.com Web site [5].
