Sort: implementation of sorting algorithms in C and CUDA

in #utopian-io5 years ago

sort

Repository of sorting algorithms in C and CUDA.

Proof of work

Information

The program generates and fills arrays in four different ways:

  1. arrays with totally random elements
  2. arrays already ordered
  3. arrays ordered in descending order
  4. arrays 90% ordered.

Sorting methods implemented

  1. Selection sort
  2. Insertion sort
  3. Shell sort
  4. Quick sort
  5. Heap sort
  6. Merge sort
  7. CUDA Quick sort
  8. CUDA Merge sort

Requirements

NVIDIA CUDA Toolkit 6.0, NVCC v6.0.1, GCC and G++

Follow these instructions to set up your environment:

Our CUDA sorting code requires devices with CUDA compute capability 3.5 or higher, in order to use
the Dinamic Parallelism technology, read more about it here:

NVIDIA blog describing Dinamic Parallelism in Kepler GPUs

Compiling

Run the MAKEFILE

Instructions

To run the program, type:

./a.out -a $algorithm -n $number_of_elements -s $state [-P]

Parameters

  1. -a sorting algorithm
  1. -n number of elements
  2. -s array state
  3. -P print results

The fastest sorting algorithm for CUDA I know of is radix sort.
It is included in the CUDA unbound library.
