A large-scale computational system is designed to process long sequences of data. To manage memory efficiently, it stores the intermediate data for each sequence in a collection of small, fixed-size blocks that are scattered across non-contiguous memory locations. While this approach significantly reduces wasted memory, one might expect a performance penalty due to the overhead of accessing scattered data. However, in this system, the performance impact is found to be minimal. What is the most likely reason for this?

Evaluating Memory Management Strategies for Large-Scale Computation

In a system that processes large data sequences, adopting a memory management strategy where data is stored in non-contiguous blocks is effective primarily because the underlying computational model is already designed to operate on data in a block-wise fashion, thus minimizing the performance impact of scattered memory access.
