Atiquzzaman, M., Performance modeling of multiprocessor systems for different data loading schemes, Microprocessing and
Microprogramming 36 (1993) 167-178.
When evaluating the performance of an algorithm in a multiprocessor system, most authors assume that the data are already
loaded in the system. This assumption gives rise to a large error between the predicted and actual performances, specially for
fine-grained tasks like image processing. Different data loading and interprocessor communication techniques can result in a
significant difference in the performance of a machine. To quantify the amount of time spent for data loading and unloading
as compared to the total processing time, different data loading and unloading schemes have been developed in this paper. A
comparison of performance of a machine under the different schemes has also been presented. The comparison will give an insight
