Abstract

The development of Java has seen increasing attention as the most popular platform for distributed computing. However, despite Java's advantages in the area of portability and rapid prototyping, its efficiency is unavoidably compromised through its commitment to portability. In this paper we present performance analysis and comparisons of evaluation results for both Java and C/Fortran on three different message-passing parallel platforms-a shared memory multi-processor (Sun E4000), a Linux cluster, and a distributed memory computer (IBM SP-2). The NAS Embarrassingly Parallel and Integer Sort benchmarks were selected for this evaluation. Both the original Fortran/C codes and Java versions of these two kernels were used for obtaining the performance measurements as part of our project. The evaluation results demonstrate the feasibility of message-passing computing with Java on a wide range of computer platforms. Depending on the system and the software components installed, significant impact on the message-passing performance will have the efficiency of the native MPI library and the version of the Java platform.

使用Java的消息传递计算:性能评估和比较

Java作为分布式计算最流行的平台，其发展受到了越来越多的关注。然而，尽管Java在可移植性和快速原型方面具有优势，但由于其对可移植性的承诺，其效率不可避免地受到损害。在本文中，我们对Java和C/Fortran在三种不同的消息传递并行平台(共享内存多处理器(Sun E4000)、Linux集群和分布式内存计算机(IBM SP-2))上的性能分析和评估结果进行了比较。NAS窘迫并行和整数排序基准被选择用于本次评估。作为我们项目的一部分，这两个内核的原始Fortran/C代码和Java版本都用于获得性能度量。评估结果表明，在广泛的计算机平台上使用Java进行消息传递计算是可行的。根据所安装的系统和软件组件的不同，本机MPI库的效率和Java平台的版本会对消息传递性能产生重大影响。
