DataFlowTasks.jl is a Julia package dedicated to parallel programming on multi-core shared memory CPUs. From user annotations (READ, WRITE, READWRITE) on program data, DataFlowTasks.jl automatically infers dependencies between parallel tasks. Behind the scenes, the user annotations are used to automatically infer task dependencies by constructing and analyzing a directed acyclic graph based on how tasks access the underlying data. The premise is that, for certain kinds of algorithms where constant re-use of data is of paramount importance for performance, it is simpler to specify how tasks depend on data than to directly specify how tasks depend on each other (e.g. manually adding synchronization primitives such as wait, fetch, etc).
