“…This contrasts to the regularity of access of voxels in the object order rendering which allows the memory bandwidth to be used more efficiency. It may decrease the memory throughput [10]. Both algorithms and the pipeline can be easily implemented in a parallel way.…”

SIMD, MIMD, MasPar, volume visualization, parallel algorithmsBiomedical volume visualization requires high quality and high performance, but the existing high performance solutions such as the Shear Warp algorithm, 3D texture mapping, and special purpose hardware have problems.Permutation warping achieves high fidelity for biomedical datasets of regular rectilinear volumes, using a one-to-one communication scheme for optimal O(1) communication on massively parallel computers. Extensions are presented including data dependent optimizations using octrees, arbitrary view angles flexibility, and multiple instruction stream multiple data stream (MIMD) implementation. A MasPar MP-2, single instruction stream multiple data stream (SIMD) (16,384 processor), implementation achieves 14 frames/second, using trilinear reconstruction on 128 3 volumes for 400% runtime improvement over our previous result. A Proteus MIMD (32 processor) implementation achieves 1 frame/second on the same data. Additionally the PermWeb software architecture is presented, that has shown as a proof of concept means to provide wide shared access to a powerful centralized rendered. All of these improvements make permutation warping an effective solution for biomedical volume visualization.
