Types

type WorkerResults

type WorkerResults struct {
	Offset int
	Extent interface{}
}

WorkerResults are the results of a scatter worker.

func Scatter

func Scatter(inputLen int, sFunc func(int, int, *sync.RWMutex) (interface{}, error)) ([]*WorkerResults, error)

Scatter scatters a computation across multiple goroutines. This breaks the task in to a number of chunks and executes those chunks in parallel with the function provided. Results returned are collected and presented a a set of WorkerResults, which can be reassembled by the calling function. Any error that occurs in the workers will be passed back to the calling function.
