Multi-Lane FlowPools: A Detailed Look

FlowPools, proposed by are a powerful way to express dataflow logic in highly parallelized applications. The original paper proposes two ways of implementing a FlowPool: Single-Lane FlowPools (SLFP) and Multi-Lane FlowPools (MLFP). While SLFPs showed decent performance overall, insertion operations do not scale. MLFPs solve this limitation as benchmarks discussed in have shown. This report goes into the details of the implementation of MLFPs and lies out the benchmarking results to show that MLFPs may reduce insertion time by 49 - 54% on a 4-core i7 machine with respect to comparable concurrent queue data structures in the Java standard library.
