Detailed Description

template<class Jobs, class RetType>
class Gecode::Support::RunJobs< Jobs, RetType >

Parallel iterator that runs jobs with a given number of threads.

It takes an iterator over jobs as input and acts as an iterator over the jobs' results. The order of iteration is not kept. The iterator runs several jobs as defined by the input iterator in parallel using a maximal number of threads.

The iterator can be stopped creating new jobs if one of the running jobs throws an exception of type JobStop. In that case the result of the stopped job is defined by the default constructor of the return type RetType. Already running jobs are not stopped and deliver their results as usual.
