This paper is concerned with complexities of parallel sorting algorithms on AGPU model.
First, we analyze known sort algorithms such as bitonic sort and GPU-Warpsort.
Next, we give a lower bound of I/O complexities of comparison-based sorting algorithms
on AGPU model. Let $b$ be the number of cores in a multiprocessor, $p$ be the total number
of cores, and $M$ be the total number of words in shared memories in multiprocessors.
Then the necessary number of global memory accesses to comparison-sort $n$ elements
is shown to be $Omega(frac{n}{b}log_{frac{M}{p}} frac{n}{b})$.
We also propose a sorting algorithm whose I/O complexity matches this lower bound.
Its time complexity is $Order(frac{n}{p}log frac{n}{b} log b)$. |
