Accelerating Leukocyte Tracking Using CUDA: A Case Study in Leveraging Manycore Coprocessors

Free registration required

Executive Summary

The availability of easily programmable manycore CPUs and GPUs has motivated investigations into how to best exploit their tremendous computational power for scientific computing. Here the authors demonstrate how a systems biology application - detection and tracking of white blood cells in video microscopy - can be accelerated by 200x using a CUDA-capable GPU. Because the algorithms and implementation challenges are common to a wide range of applications, they discuss general techniques that allow programmers to make efficient use of a manycore GPU.
