A vectorized code for the pseudofermion simulation of QCD with dynamical quarks

Abstract
We present a FORTRAN code for the Monte Carlo simulation of Quantum Chromodynamics with dynamical fermions, using the pseudofermion algorithm. The code is fully vectorized and optimized for the CDC CYBER 205, taking advantage of high performance features like 32-bit arithmetic, gather/scatter hardware and asynchronous I/O. Nonetheless, the code is largely portable and performs well on other vector computers.

Title of program: PSEUDOF
Catalogue Id: ABDH_v1_0

Nature of problem
Monte Carlo simulations of Quantum Chromodynamics (QCD) often neglect the effects of virtual quark loops. These effects can be included using the pseudofermion algorithm, giving a complete solution of QCD and a more accurate description of hadronic phenomena.

摘要：本文提出一种基于 FORTRAN 编写的量子色动力学（QCD）蒙特卡洛模拟程序，该程序采用伪费米子算法模拟动态费米子。该代码经过完全向量化和针对 CDC CYBER 205 的优化，充分利用了32位算术、汇集/散射硬件和异步I/O等高性能特性。尽管如此，该代码具有很高的可移植性，并在其他向量计算机上表现出良好的性能。

程序标题：PSEUDOF

目录编号：ABDH_v1_0

问题性质：蒙特卡洛模拟量子色动力学（QCD）通常忽略虚夸克环效应。通过伪费米子算法可以包括这些效应，从而给出QCD的完整解，并对强子现象提供更精确的描述。
