| Research Abstract |
This study dealt with the GRID middleware and parallel processing to realize image processing for medicine on computational GRID.
1. The following systems are developed.
(1) A resource monitoring and selection method for rapid turnaround grid applications (for example, within 10 seconds)
(2) A robust instrumentation method that is capable of generating large traces beyond the capacity of physical memory, aiming at analyzing the performance of large-scale parallel programs
(3)A resource selection method for the GPU Grid, which utilizes the GPU as computational resources of the Grid
(4) A robust instrumentation method that is capable of generating large traces beyond the capacity of physical memory, aiming at analyzing the performance of large-scale parallel programs
2.The following parallel algorithms are designed and implemented.
(1) A nonrigid registration algorithm for investigating lung disease on PC clusters
(2) A range of motion estimation method that is capable of fine-grained estimation during total hip replacement (THR) surgery
(3) A biplane 2-D/3-D rigid registration using commodity Graphics Hardware (GPU)
(4) A two-stage compression method for accelerating programmable GPU-based volume rendering of time-varying data
(5) An efficient parallel volume rendering algorithm for visualization of large-scale datasets
(6) An instruction allocation method that is capable of reducing the FP workload by moving some instructions from the FP program to the VP program, both written in a GPU assembly language.
(7) An LU decomposition algorithm on the programmable GPU
