This paper describes an end-to-end system implementation of a transactional memory (TM) programming model on top of the hardware transactional memory (HTM) of the Blue Gene/Q machine. The TM programming model supports most C/C++ programming constructs using a best-effort HTM and the help of a complete software stack including the compiler, the kernel, and the TM runtime. An extensive evaluation of...
Nowadays, the applications of MPI-based clusters are used widely, such as the damage prediction of nuclear explosion and gene decryption. However, the usages of MPIbased heterogeneous cluster are nearly reported in contrast to the MPI-based homogeneous clusters due to the immature technology. This paper focuses on building a MPI based heterogeneous cluster with the MPICH2, which is released last year...
This paper presents a parallel multi-resolution volume rendering algorithm based on graphics processing unit (GPU). The algorithm is based on several important criteria, rendering is done adaptively by selecting high-resolution cells close to a center of attention and low-resolution cells away from this area. We employ the 3D texture mapping capability commonly available in modern GPU as a core rendering...
This paper proposes a 3D volume clipping method based on volume distance field, which is suitable for texture-based volume rendering and exploit per-fragment operation on the graphics hardware to implement clipping. High frame rates are achieved and therefore interactive explorations and clippings of volume data are supported.
In this paper, we present an efficient, high-quality volume rendering algorithm using GPUs for rendering large CT datasets at interactive frame rates on standard PC hardware. We subdivide the volume dataset into uniform sized blocks and take advantage of combinations of early ray termination, empty-space skipping and visibility culling to accelerate the whole rendering process and render visible parts...
