  We present and evaluate GPU Bucket Sort, a parallel deterministic sample sort
algorithm for many-core GPUs. Our method is considerably faster than Thrust
Merge (Satish et.al., Proc. IPDPS 2009), the best comparison-based sorting
algorithm for GPUs, and it is as fast as the new randomized sample sort for
GPUs by Leischner et.al. (to appear in Proc. IPDPS 2010). Our deterministic
sample sort has the advantage that bucket sizes are guaranteed and therefore
its running time does not have the input data dependent fluctuations that can
occur for randomized sample sort.
