Compiling programs
PDS Lab cluster supports GNU compilers to compile your serial programs, MPI programs, OpenMP program and Hybrid MPI/OpenMP programs.
Serial programs
To compile and link a serial program in Fortran, C, and C++, you can use one of these commands:
f77 /path/to/myprog.f g77 /path/to/myprog.f gfortran /path/to/myprog.f gcc /path/to/myprog.c g++ /path/to/myprog.cpp
MPI programs
There are 3 MPI implementations available on the system: MVAPICH, OpenMPI, and MPICH.
You may explicitly add one of the other available MPI implementations to your environment via the soft add command to use the compilers shown.
| MPI Implementation | Compile Commands |
|---|---|
|
MVAPICH |
Fortran 77: mpif77 /path/to/myprog.f Fortran 90: mpif90 /path/to/myprog.f90 C : mpicc /path/to/myprog.c C++ : mpiCC /path/to/myprog.cpp
|
| Open MPI | |
| MPICH |
OpenMP programs
To compile and link an OpenMP program in Fortran, C and C++, use the -fopenmp option on compiling command:
gfortran -fopenmp /path/to/myprog.f gcc -fopenmp /path/to/myprog.c g++ -fopenmp /path/to/myprog.cpp
Hybrid MPI/OpenMP programs
To compile and link an MPI/OpenMP hybrid program, use the -fopenmp option with the MPI compling commands:
mpif77 -fopenmp /path/to/myprog.f mpif90 -fopenmp /path/to/myprog.f90 mpicc -fopenmp /path/to/myprog.c mpiCC -fopenmp /path/to/myprog.cc
