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.
