MPI fortran code compiled in linux and windows with cygwin
To compile an MPI (Message Passing Interface) Fortran code in Linux and Windows using Cygwin, you can follow these steps:
Install the necessary software:
- Linux: Ensure that you have an MPI implementation installed on your Linux system, such as Open MPI or MPICH.
- Windows with Cygwin: Install Cygwin on your Windows machine. During the installation, make sure to select the necessary MPI-related packages, such as
openmpi
,mpich
, oropenmpi-devel
, depending on your preferred MPI implementation.
Write your MPI Fortran code:
Create your MPI Fortran code using a text editor. Save the code with a.f90
or.f95
extension.Compile on Linux:
Open a terminal and navigate to the directory containing your MPI Fortran code. Compile the code using the appropriate MPI compiler command. For example, with Open MPI:bashmpifort -o program_name program_code.f90
Replace
program_name
with the desired name of the compiled executable, andprogram_code.f90
with the name of your Fortran source file.Compile on Windows with Cygwin:
Open the Cygwin terminal and navigate to the directory containing your MPI Fortran code. Compile the code using the same MPI compiler command as on Linux. For example, with Open MPI:bashmpifort -o program_name program_code.f90
The compilation process should be similar to the Linux environment.
Run the MPI executable:
After successful compilation, you can run the MPI executable using the appropriate command. For example:bashmpirun -np <num_processes> ./program_name
Replace
<num_processes>
with the desired number of MPI processes you want to run.
It's important to note that the specific commands and steps may vary depending on your MPI implementation and the Fortran compiler available on your systems. Make sure you have the necessary MPI packages installed and properly configured in both environments. Additionally, consider any platform-specific considerations or limitations when using MPI on Windows with Cygwin.
Refer to the documentation of your MPI implementation and Fortran compiler for more detailed instructions and guidance on compiling and running MPI Fortran code in Linux and Windows with Cygwin.
