Abstract

SimSET is a package for simulation of emission tomography data sets. Condor is a popular distributed computing environment. Simple C/C++ applications and shell scripts are presented which allow the execution of SimSET on the Condor environment. This is accomplished without any modification to SimSET by executing multiple instances and using its combinebin utility. This enables research facilities without dedicated parallel computing systems to utilize the idle cycles of desktop workstations to greatly reduce the run times of their SimSET simulations. The necessary steps to implement this approach in other environments are presented along with sample results.

摘要

SimSET是一个用于模拟发射断层扫描数据集的软件包。Condor是一个广受欢迎的分布式计算环境。本文展示了简单的C/C++应用程序和 shell 脚本，它们可以在Condor环境中执行SimSET。通过执行多个实例并使用其combinebin实用程序，无需对SimSET进行任何修改即可实现这一点。这使得没有专用并行计算系统的研究机构能够利用桌面工作站的空闲周期，从而大大减少其SimSET模拟的运行时间。文中还介绍了在其他环境中实施此方法的必要步骤以及示例结果。
