Additional Inherited Members
Properties inherited from DotMP.Schedule
static Schedule	Static `[get]`
	The static scheduling strategy. Iterations are divided amongst threads in round-robin fashion. Each thread gets a 'chunk' of iterations, determined by the chunk size. If no chunk size is specified, it's computed as total iterations divided by number of threads. More...

static Schedule	Dynamic `[get]`
	The dynamic scheduling strategy. Iterations are managed in a central queue. Threads fetch chunks of iterations from this queue when they have no assigned work. If no chunk size is defined, a basic heuristic is used to determine a chunk size. More...

static Schedule	Guided `[get]`
	The guided scheduling strategy. Similar to dynamic, but the chunk size starts larger and shrinks as iterations are consumed. The shrinking formula is based on the remaining iterations divided by the number of threads. The chunk size parameter sets a minimum chunk size. More...

static Schedule	Runtime `[get]`
	Runtime-defined scheduling strategy. Schedule is determined by the 'OMP_SCHEDULE' environment variable. Expected format: "schedule[,chunk_size]", e.g., "static,128", "guided", or "dynamic,3". More...

static Schedule	WorkStealing `[get]`
	The work-stealing scheduling strategy. Each thread gets its own local queue of iterations to execute. If a thread's queue is empty, it randomly selects another thread's queue as its "victim" and steals half of its remaining iterations. The chunk size parameter specifies how many iterations a thread should execute from its local queue at a time. More...
