Aditya's graphics and game related adventures

A GPGPU based implementation of Hybrid Genetic Algorithm and Particle Swarm Optimization for Function Optimization

Presented this Poster at HiPC 2011 as the primary Author. Please email me if you want information about this one. The program is written in C using openCL.

GPU Sort and Max element finder

              Did some experiments in GPU computing. So I just created this simple Library using openCL called floatCL which is used to manipulate float arrays. A parallel sorting algorithm and finding the largest element in an array have been implemented.

Time Complexity (for PRAM):

1. Sorting - O(n)

2. Largest element - O(1)
