I'm reading the textbook for my parallel system course and I found these two popular notions:
Can someone tell me the difference? For me, Tseq is semantically (and pratically) equal to Tpar(1)
Update after answers:
I think that I understood the difference, but I have still a question: I'm optimizing this code. In order to make my parallel version well-balanced, an approximate result is used. The difference is very small and be considered negligible, but the workload is greatly balanced and scalability greatly improves from that.
In addition, I did some optimizations, like using raw-pointers instead of data structures built upon them (e.g. cv::Mat) used in the original code.
So my question is: to measure speedup should I use the original code (the one that I linked) or would be like cheating?
