E. Alternative IDE: Geany

Geany is a small and fast IDE with flexible compilation option. We can compile MPI program directly from the source code without having to make a project first. For Geany in order to be able to compile C program, we must install Dev-Cpp first, it uses the GCC compiler. After that, follow these steps:

1. Install Geany 0.18.
   Extra: download MPI tags file and copy to:

   "C:\Documents and Settings\%USERNAME%\Application Data\Geany\tags"

2. Create MPI program in C using Geany.
3. Set compilation for MPI, Build - Set Includes and Arguments.
   • Compile:

     C:\Dev-Cpp\bin\gcc.exe "%f" -o "%e.exe" -I "C:\Dev-Cpp\include" -I "C:\Program Files\MPICH2\include" -L "C:\Dev-Cpp\lib" -L "C:\Program Files\MPICH2\lib" "C:\Program Files\MPICH2\lib\mpi.lib"

   • Execute: (here number of processes is 5)

     "C:\Program Files\MPICH2\bin\mpiexec.exe" -n 5 "%e"
