....gather and scatter instructions, which can do random access fetches (and stores, respectively) in vector mode. It is these machines that have the ability to do garbage collection in vector mode. Processing the queue in a breadth first search algorithm is a natural application of parallel processing[3], and the gather and scatter instructions can be used for this purpose. A large batch of queue entries can be removed at once from the head of the queue, processed in parallel, and a new batch of entries can be appended to the tail. This is the principal idea behind our algorithm. Since ....
