  trivially parallel workload is trivial in pretty much any language though.

    Still easy to mess up the coordination when you have mutable shared state.

      Embarrassingly parallel workloads kinda don't have mutable shared state... that's why they're "embarrassing".
      • brazzy 7y ago
        No. "Embarassingly parallel" just means you don't need to share intermediate results. You still need to create all the parallel threads/processes/fibers/whatever, divide the work between them and collect or merge the results. And if you work in an environment where state is mutable and shared per default (i.e. your typical shared-memory multithreaded Java/C#/C++/Ruby program), then it's still very easy to mess up somewhere.
