How did you coordinate those reads and writes? A writer not having exclusive access to what it's writing to, at the time of the writing... sounds... very bad. > sell me on why I need data parallelism. Just to name one example: machine learning. If you're feeding real-time data to a ML algorithm, chances are you'll have to perform multiple independent calculations that use the same data as input. To speed up those calculations, you need to perform them in parallel.
