Package jasima.core.expExecution

Class ThreadPoolExecutor

java.lang.Object

jasima.core.expExecution.ExperimentExecutor

jasima.core.expExecution.ThreadPoolExecutor

public class ThreadPoolExecutor
extends ExperimentExecutor

Default implementation of an ExecutorFactory returning an Executor that uses up to Runtime.getRuntime().availableProcessors() threads to execute tasks concurrently. This number of threads can be overridden by setting the system property "jasima.core.expExecution.ThreadPoolExecutor.numThreads".

In order to prevent starvation of worker threads waiting for sub-experiments to complete, there is a thread pool for each nesting level of experiments.
