In today's world, sorting is a basic need and appropriate method starts with searching. Several sorting algorithms has been developed on CPU (Central Processing Unit). But according to current scenario, CPU is not so efficient in sorting. To get the more speedup of sorting algorithms parallelization should b e done. There are many ways of Parallelizing sorting methods which can be performed by using...
Decoding low-density parity-check (LDPC) codes requires a lot of computation time, particularly when bit error rates as low as 10-9 are needed. In this paper, we improve the simulation speed by making use of an inexpensive graphics processing unit (GPU). A dedicated program is written to utilize the hardware resources in the GPU to decode LDPC codes in a parallel manner. Codes with rate 1/2 and length...
Breadth-first search (BFS) has wide applications in electronic design automation (EDA) as well as in other fields. Researchers have tried to accelerate BFS on the GPU, but the two published works are both asymptotically slower than the fastest CPU implementation. In this paper, we present a new GPU implementation of BFS that uses a hierarchical queue management technique and a three-layer kernel arrangement...
