摘要

提出了一种并行的无损压缩算法。该算法基于三维小波变换(3D WT)。所研究的系统由一个并行实现的小波压缩软件组成，该软件运行在一个由高性能局域网Myrinet连接的8个节点的集群上。并行实现基于标准消息传递接口(MPI)。我们已经使用了MPI标准的三种实现:MPI- bip、MPICH和LAM。最后给出了这三种实现的实验结果。给出了该并行系统在压缩视频序列中的性能结果。报告并解决了该系统在TCP实现效率方面存在的一些问题。

3D wavelet compression by message passing on a Myrinet cluster

We present a parallel algorithm for lossless compression. The algorithm is based on the 3D wavelet transform (3-D WT). The system under study consists of a parallel implementation of a wavelet compression software running on a cluster of eight nodes linked by a high performance local area network, Myrinet. The parallel implementation is based on the standard message passing interface (MPI). We have used three implementations of the MPI standard: MPI-BIP, MPICH, and LAM. Experimental results are reported based on these three implementations. We provide performance results of this parallel system for the compression video sequences. Some bugs in the efficiency for TCP implementation are reported and resolved for this system.
