采用并行计算的手段,数值模拟程序可以在高性能计算环境下获得数值求解加速,但在短时间内输出的大量、多块的计算结果,也为研究者的数据分析造成了困难.为此,本文介绍了一个针对并行计算程序的远程跟踪可视化系统,它适合运行于并行分布式计算环境,用户只需简单改造数值程序,即可通过远程终端对运行期的程序进行自动计算跟踪和交互可视化,而跟踪系统的优化设计则使数值程序的远程交互延迟得到有效控制.

High performance computer give scientists the power to simulate scientific problem quickly with parallel processes. The larger multi-block data produced by such simulations, however, present great challenges to the following data visualization and analysis task. This paper introduces a visualization system, which can remotely steer and study the parallel program running on distributed-memory high performance computer by simple add steering code. The whole system can lessen delay of simulation program, and provide interactive capacities for user.
