Fortran&OpenMP - 1.环境配置

编译OpenMP程序的时候，需要在编译源文件和连接时都加入‘-fopenmp’编译选项。
以Code::Blocks13.11为例，需要在'Project'-'Build Option'-'Compiler Flags'中勾选'Enable the OpenMP extensions [-fopenmp]'；



在同一窗口的‘Linker Settings’-‘Other Linker Options’中加入“-fopenmp”



环境设置完毕，可以进行程序编辑了。

program main
implicit none
include 'omp_lib.h'
integer :: threadCount
integer :: threadNum
!$OMP PARALLEL PRIVATE(threadCount, threadNum)
threadCount = OMP_GET_NUM_THREADS()
threadNum = OMP_GET_THREAD_NUM()
write(*, "('THREAD: ', I2, '/', I2)") threadNum, threadCount
!$OMP END PARALLEL
end program
