FortranでもPythonみたいにインタラクティブモードしたい！と思い、シェルスクリプトで作ってみました。
自作モジュールを使用することもできます。
なお、自作モジュールは -c オプションでコンパイルして、./inc/内にオブジェクトファイルを、./に.modファイルをおいておいてください。

1 例1: 使用するcpuコア数を変更する。

cpu-coreと打ちます。


>
Initializing ...
Please input fortran script *.f90 | or check manual by 'man'  
  
>>> cpu-core

ちょっと文句言われますが、コア数変更に進みます。デフォルトは1コアなので、４コアに変更してみます。


>
Initializing ...
Please input fortran script *.f90 | or check manual by 'man'  
  
>>> cpu-core

./Interactive/SiCroF: 66: [: man: unexpected operator
./Interactive/SiCroF: 70: [: man: unexpected operator
Current num of cpu-core is :: 1 
Please input num of cpu-core
4

すると、コア数が変更できます。


>

Please input fortran script *.f90 | or check manual by 'man'  
  
>>> ^C%

Current num of cpu-core is :: 4 
>>>

また、.f90拡張子のついたファイルを./inc/以下のオブジェクトファイルとリンクしてコンパイル、指定したコア数で実行します。
試しに、MPI版HelloWorldをやってみます。

program mpihello
    use MPIClass
    implicit none

    type(MPI_) :: mpid

    call mpid%start()
    print *, "Hello, my rank is :: ", mpid%MyRank
    call mpid%end()
end program

ここに、MPIClassは自作のクラスです(Appendix参照)

実行結果はこのようになります。



>>> mpihello.f90
./Interactive/SiCroF: 66: [: man: unexpected operator
./Interactive/SiCroF: 70: [: man: unexpected operator
