The reason is that laziness and higherorder complicates basic debugging strategies. Although there exist several debuggers for sequential lazy languages, dealing with parallel languages is much harder. In this case, it is important to implement debugging platforms for parallel extensions, but it is also important to provide theoretical foundations to simplify the task of understanding the debugging process. In this work, we deal with the debugging process in two parallel languages that extend the lazy language Haskell. In particular, we provide an operational semantics that allows us to reason about our parallel extension of the sequential debugger Hood. In addition, we show how we can use it to analyze the amount of speculative work done by the processes, so that it can be used to optimize their use of resources. 2227-7390 10.3390/math8060864 https://hdl.handle.net/20.500.14352/6439 https://doi.org/10.3390/math8060864 https://www.mdpi.com/2227-7390/8/6/864 A Semantic Framework to Debug Parallel Lazy Functional Languages
