Webeach chunk of indexes. If this is not the case, we need to use DYNAMIC option in SCHEDULE clause. • DYNAMIC has a parameter, chunk, which defines the number of indexes assigned the each thread. The first thread to finish its job takes the next available chunk. Parameter chunk is a variable. It can be assigned inside the code. Webschedule(guided, [, chunk]): similar to dynamic, but block size decreases exponentially from an implementation-defined value to chunk However, not all loops can be parallelized this way. In order to split the workload as shown there must not be any dependencies between the iterations, i.e. no thread may write to a memory location that another thread …
