In addition to a common architecture, Scala’s parallel collections library additionally shares extensibility with the sequential collections library. That is, like normal sequential collections, users can integrate their own collection types and automatically inherit all the predefined (parallel) operations available on the other parallel collections in the standard library.
Scala Collections Hierarchy. ▷ Traversable[T] – collection of elements ... A sequential collection can be converted into a parallel one by calling par.
Conceptually, Scala's parallel collections framework parallelizes an operation on a parallel collection by recursively “splitting” a given collection, applying ...

Jan 18, 2022 · Scala programming language already brings us a collection to quickly implement parallel computing, the Parallel Collections. In this tutorial, we’ll check out some concepts of parallelism with Scala and the usage of parallel collections. 2. Parallelism Overview It’s important to understand that parallelism has efficiency as the primary goal.
Every sequential collection can be converted to its parallel variant using the par method. Certain sequential collections have a direct parallel counterpart.
Here is a way to change the task support of a parallel collection: import scala.collection.parallel._ val pc = mutable.ParArray (1, 2, 3) pc.tasksupport = new …
A ParArray sequence holds a linear, contiguous array of elements. This means that the elements can be accessed and updated efficiently by modifying the underlying array. Traversing the elements is also very efficient for this reason. Parallel arrays are like arrays in the sense that their size is constant.
