Processing-Mode Equality

[Sam Pullara]

Since parallel execution using this framework is fundamentally more expensive than sequential (CPU, memory and synchronization overhead) they are not the same. If developers use this framework and ignore that overhead they will see huge slowdowns on one side and OOMEs on the other. It might be beautiful to think of them as the same thing, but until we make sequential the common degenerate case of parallel based on metrics, I don't think people should think of it that way.
