1. In a multiple processor computer system, a computer-implemented method comprising: pre-assigning an iterator thread to a dedicated processor in the multiple processor system; initiating the iterator thread at a start of a basic code block, ahead of a code block for a nested loop; pre-computing, via the iterator thread, indices for a multidimensional array associated with the nested loop; inserting the pre-computed indices as entries within a queue; initiating iteration of the multi-dimensional array associated with the code block for the nested loop; dequeueing an entry from the queue to access the array on which the iteration is initiated utilizing the dequeued entry; and performing iterations on the array by using the queue entries.
