Compiling Serial Programs

A serial program is a single process which executes as a sequential stream of instructions on one processor core. Compilers capable of serial programming are available for C, C++, and versions of Fortran.

Here are a few sample serial programs:

• serial_hello.f
• serial_hello.f90
• serial_hello.f95
• serial_hello.c
• serial_hello.cpp

To load a compiler, enter one of the following:

$ module load intel
$ module load gcc

The following table illustrates how to compile your serial program:

Language	Intel Compiler	GNU Compiler
Fortran 77	$ ifx myprogram.f -o myprogram	$ gfortran myprogram.f -o myprogram
Fortran 90	$ ifx myprogram.f90 -o myprogram	$ gfortran myprogram.f90 -o myprogram
Fortran 95	$ ifx myprogram.f90 -o myprogram	$ gfortran myprogram.f95 -o myprogram
C	$ icx myprogram.c -o myprogram	$ gcc myprogram.c -o myprogram
C++	$ icpx myprogram.cpp -o myprogram	$ g++ myprogram.cpp -o myprogram

The Intel and GNU compilers will not output anything for a successful compilation. Also, the Intel compiler does not recognize the suffix .f95.
