void ParallelFor
(
int32 Num,
TFunctionRef < void)> Body,
EParallelForFlags Flags
)
Remarks
General purpose parallel for that uses the taskgraph for unbalanced tasks Offers better work distribution among threads at the cost of a little bit more synchronization. This should be used for tasks with highly variable computational time.
Parameters
| Name | Description |
|---|---|
| Num; | number of calls of Body; Body(0), Body(1)....Body(Num - 1) |
| Body; | Function to call from multiple threads |
| Flags; | Used to customize the behavior of the ParallelFor if needed. Notes: Please add stats around to calls to parallel for and within your lambda as appropriate. Do not clog the task graph with long running tasks or tasks that block. |
