Parallel collections are meant to be used in exactly the same way assequential collections– the only noteworthy difference is how to obtainaparallel collection. Generally, one has two choices for creating a parallel collection: First, by using the newkeyword and a proper import statement: Second, by convertingfro… Näytä lisää

May 23, 2012 · Since parallel collections support nested parallelism, the actual thread pool implementation may allocate more threads to run the query if it detects this is necessary. EDIT: Starting from Scala 2.10, the preferred way to set the parallelism level is through setting the tasksupport field to a new TaskSupport object, as in the following example:

VerkkoIn order to build for Scala 3, we had to rename some inner classes. Technically, this broke binary compatibility with 0.2.0. Ordinary code that uses the built-in parallel …

The ExecutionContextTaskSupport uses the default execution context implementation found in scala.concurrent, and it reuses the thread pool used in scala.concurrent (this is either a fork join pool or a thread pool executor, depending on the JVM version). The execution context task support is set to each parallel collection by default, so parallel collections reuse the same fork-join pool as the future API.

The design of Scala’s parallel collections library is inspired by and deeply integrated with Scala’s (sequential) collections library (introduced in 2.8). It provides a parallel counterpart to a number of important data structures from Scala’s (sequential) collection library, including: ParArray. ParVector. mutable.ParHashMap. mutable.ParHashSet.

As already said, Scala implements collections to work with parallelism. The main sequential collection is integrated with parallel ones. Let's ...
