ACCU 2012 Data-flow Parallelism

Data Flow Library - Parallel Pixie Dust

Mid 50s first parallel computer

How to implement multi-threaded debuggers - very difficult - uses difference states, but not complete answer.

PPD - for general purpose threading.

for_each - best to make linear and avoid locks
accumulate needs to be both comutative and associative.

Consider: swap pointers not actual data items. also std::move in C++11.

Need to look at the design or algorithms mainly so they can be parallelized.
