Abstract
A new numerical approach by Furmanski and Kolawa to quantum chromodynamics is based on diagonalizing the underlying Hamiltonian. This method involves the generation of states by repeated action of a potential operator. This symbolic calculation is dominated by the time it takes to search the database of existing states to verify if a generated state is identical to one previously found. We implement this algorithm on the Caltech/JPL Mark II hypercube and analyze its performance of both a simple database search and one optimized for this application. We show that the hypercube performance can be modelled in a fashion similar to conventional numerical (loosely synchronous) applications.
Furmanski和Kolawa提出的量子色动力学的一种新的数值方法是基于对角化底层哈密顿量。这种方法涉及到通过一个潜在算子的重复动作来产生状态。这种符号计算主要取决于搜索现有状态数据库以验证生成的状态是否与先前发现的状态相同所花费的时间。我们在Caltech/JPL Mark II超立方体上实现了该算法,并分析了其简单数据库搜索和针对该应用程序优化的数据库搜索的性能。我们展示了超立方体性能可以以类似于传统数值(松散同步)应用程序的方式建模。
