是的,Linux上安装的Gfortran(GNU Fortran Compiler)支持多线程
要在Linux上安装Gfortran,请根据您的发行版使用相应的包管理器。例如,在Debian和Ubuntu系统上,您可以使用以下命令安装:
sudo apt-get update
sudo apt-get install gfortran
在Fedora和RHEL系统上,您可以使用以下命令安装:
sudo dnf install gcc-gfortran
安装完成后,您可以通过运行gfortran -v
来检查Gfortran的版本和配置。如果一切正常,您将看到与多线程相关的信息,例如:
gcc (Ubuntu 9.3.0-17ubuntu1~20.04) 9.3.0

请注意,这些警告表明Gfortran支持OpenMP并行编程库,但某些C和C++标准可能不支持它。要使用OpenMP并行功能,请在编译时添加-fopenmp
选项,例如:
gfortran -fopenmp myfile.f90 -o myfile
