[Hackathon] Stabilize oneTBB Example Benchmarks 1

[sarathnandu]

Summary

Several oneTBB examples serve as performance benchmarks for the library. It's recommended to check the relative error for these examples. If the relative error exceeds 5%, consider stabilizing the example to improve the reproducibility of results, while still maintaining a reasonable execution time.

Additional task Conduct scalability analysis and see if the examples are scalable in the given HW. See modifying the input parameters like dataSize improve scalability.

Target Examples

seismic : https://github.com/uxlfoundation/oneTBB/tree/master/examples/parallel_for/seismic can be considered as reference for the usage of a utility class for Relative Error compute. https://github.com/uxlfoundation/oneTBB/blob/af1a128a933a2ea0c84e4b647e389585463b7db4/examples/common/utility/utility.hpp#L362
