The benchmark testing shows that the performance of CAF programs is similar to that of MPI programs, with our CAF compiler.%Co-Array Fortran(CAF)已经成为Fortran语言标准的一部分,在科学计算领域逐渐被接受.基于软件共享存储实现了一个CAF编译器,其通过直接的数组赋值实现Co-array数据通信,利用数据垫塞技术...

Fortran2008及之后版本的主要提升在于混合编程和并行编程,并行编程通过coarray实现,想将Fortran的并行操作变成与数组操作一样简单,将Fortran变为一个天然的并行编程语言。 目前的fortran编译器基本上都内在的支持coarray,只需要在编译选项中添加一些选项就可以编译coarray程序。对gfortran, 添加选项 对intel fortran添加选项 ...
Coarray是Fortran中的一种并行范式,长久以来Fortran中没有一种统一的并行方式,而是通过调用第三方工具进行实现。其中出名的工具包有OpenMP、OpenMPI,MPICH、OpenACC。MPI是多进程,OpenMPI,MPICH的语法是相同的,只是对MPI标准的不同实现,不过OpenMPI似乎bugs有点多,不太建议使用,MPICH暂时还没有遇到什么问题。OpenMP为多线...
接下来,我们必须要考虑数据的分发过程。 Fortran语言的Co-array扩展,允许程序员可以使用一个非常类似于通常 Fortran 数组表示的语法,来表明不同内存镜像之间的关系,从而实现数据的分发。 在如下的例子中,一个新的对象,coarray ("集合数组“), 被添加到原有的语言规范中: ...
Coarray Fortran是一种并行编程模型,它扩展了Fortran语言,使得开发人员能够更方便地编写并行程序。Coarray Fortran中的数组未更新是指在并行程序中,某个数组的值没有被正确...

I am trying to understand how a Coarray Fortran DLL can be possibly called from Python. Consider the following sample Fortran module file `example_mod.f90` which is to be called from Python later: module example_mod use iso_c_binding implicit none #ifdef COARRAY_ENABLED integer ::...

I am having a bizarre "Internal Compiler Error" issue with a co-array Fortran code, only with the Debug compilation. The code compiles with no issues using IFORT 2021.6.0 (oneAPI_2022.1.0); now I am trying to compile with the latest IFORT distribution. I am als...
