Abstract
A 512 node IBM Scalable POWERParallel Systems SP2 was installed at the Cornell Theory Center in October 1994. During the past couple of months we have been porting and optimizing code for carrying out lattice QCD calculations. Present performance is far from ideal, however, and optimization efforts are still under way. The rate limiting step in our code involves a rather generic inversion of a large, sparse system, based on a partial differential equation in a multidimensional space. The insights we have gained so far may be useful in diagnosing performance in a wide class of applications.
1994年10月，一台512节点的IBM可伸缩POWERParallel Systems SP2安装在康奈尔理论中心。在过去的几个月里，我们一直在移植和优化执行晶格QCD计算的代码。然而，目前的性能远非理想，优化工作仍在进行中。我们代码中的速率限制步骤涉及基于多维空间中的偏微分方程的大型稀疏系统的相当一般的反转。到目前为止，我们获得的见解可能有助于诊断各种应用程序的性能。
