However, it isn't working as of now … Weblevel, each of 4 processors can work on disjoint sets of 2 separate data items and merge them together. Once those are done, 2 processors can each work on merging to create a list of 4 sorted items, and finally, one last processor can merge those 2 lists of 4 to create the final list of 8 sorted items. This becomes our parallel merge sort ...
