Optimizing Iterative Data-Flow Scientific Applications Using Directed Cyclic Graphs
IEEE Access, 2023 Data-flow programming models have become a popular choice for writing parallel applications as an alternative to traditional work-sharing parallelism. They are better suited to write applications with irregular parallelism that can present load imbalance.

OpenPMX Software for Nonlinear Mixed-Effect Models in Pharmacometrics: Precision Compared With NONMEM First-Order Conditional Estimation. [PDF]
CPT Pharmacometrics Syst PharmacolABSTRACT Mixed effects models are a backbone of pharmacometrics, and NONMEM software, with the first‐order conditional method with interaction having become the de facto industry standard for model estimation. Documentation exists for the general mathematical methodology for estimation, but many technical and implementation details are lacking. OpenPMX

On the Benefits of Tasking with OpenMP [PDF]
, 2019 Tasking promises a model to program parallel applications that provides intuitive semantics. In the case of tasks with dependences, it also promises better load balancing by removing global synchronizations (barriers), and potential for improved locality. Still, the adoption of tasking in production HPC codes has been slow.
