AFAIK, in the parallel world, merge sort and radix sort are the only two
algorithms used.
Without the special parallel optimizations though, they tend to
underperform compared to smarter algorithms.

There is room for different algorithms depending on the size of the data
set, the architecture, and the type/size of the input itself.
