In the medical field, volume rendering provides good quality 3D visualizations but is still not enough interactive for a day-to-day practice. The most efficient sequential algorithm is the shear-warp algorithm. It renders up to 10 images per second for a small dataset. The goal of this report is to present an efficient parallel implementation of the shear-warp algorithm for a distributed memory architecture, a cluster of PCs connected with a high speed network. This highly irregular algorithm led us to implement a dynamic load balancing algorithm. Furthermore, to reduce the overhead due to data redistribution, we overlap communications with computations using MPI's asynchronous communications. Using a good load-balancing and communication o...
