  loop vectorization
Due to its internal structure, Fftw cannot be vectorized using compilers focusing on loop vectorization.
      
The same transformation would have been beneficial for VIRAM, as it would allow outer-loop vectorization and would lead to long vectors.
      
The traditional loop vectorization techniques can be used to exploit this feature.
      


The paper [2] introduced a method of the vectorization of the serial Do-loops FORTRAN. Using this method to vector the serial FORTRAN program, we must normalize the recongition graph. From the paper [2], This paper advances concepts of condensation-recongnition gragh and strong-maximum path-length In the light of the strong-maximum path-length of every point, It is easy to normalize the recongnition gragh. This paper give a program in BASIC-language.

文[2]提出了一种将串行FORTRAN内层DO循环向量化的方法,在运用这种方法对串行FORTRAN程序向量化时,要把识别图规范化,本文在文[2]的基础上,提出了凝聚识别图和强最大路长的概念,根据图中各点的强最大路长即可很方便地将凝聚识别图规范化。本文作者用BASIC语言编出了程序,且已在机器上通过,并对文中的例子作了实际验证。

In this paper, the problems on vectorization of FORTRAN inner DO-loop are discussed. According to the formulae derived in this paper, the time sequence dependent relational graph exactly corresponding to the body of a DO-loop can be constructed under some given conditions. By removing those vertices of which incoming degrees and outgoing degrees are equal to zero, the vectorizaible statements in the loop can be obtained, and an algorithm for determining the statement sequence and introducing the temporary array...

In this paper, the problems on vectorization of FORTRAN inner DO-loop are discussed. According to the formulae derived in this paper, the time sequence dependent relational graph exactly corresponding to the body of a DO-loop can be constructed under some given conditions. By removing those vertices of which incoming degrees and outgoing degrees are equal to zero, the vectorizaible statements in the loop can be obtained, and an algorithm for determining the statement sequence and introducing the temporary array is given simultaneously.

本文讨论FORTRAN内层DO循环的向量化问题。对于满足给定条件的DO循环,根据文中导出的计算公式,可以精确地构造出与循环体相对应的时序依赖关系图。按照判别一个有向图是否存在有向回路的充要条件,采取逐个消去图中某些出度或入度为零的顶点的“消元法”,找出循环体中可以向量化的语句,并统一讨论了确定语句顺序和引进临时数组的算法。

By studying the functional properties of index expressions of array elements in FORTRAN DO-loops, a new algorithm, called the associative function algorithm, is developed. In this algorithm, when the index expression of an array element in a loop is a linear function of the controlled variable of that loop, a sufficient-necessary condition for vectorization is given,otherwise a sufficient condition is given. The algorithm puts fewer strains on the index expressions of array elements and is easy to realize.

本文通过对FORTRAN DO循环中数组元素下标式的函数性态的分析研究,给出了一种新的向量化算法——这种算法作者称为“相关函数法”。FORTRAN DO循环向量化的相关函数法,对于循环中数组元素的下标式是循环控制变量的非线性函数时,给出了向量化的充分性准则;对于数组元素的下标式是循环控制变量的线性函数时,则给出了向量化的充分必要条件,本算法的特点是:由于对数组元素的下标式限制少,并且算法简便,所以适应面广,易于在机器上实现。
