Compilers

Compilers are tools that allow you to create executable binaries from source code.

Available Compilers

Palmetto offers the following compiler suites for C, C++ and Fortran applications:

1. GNU Compiler Collection (gcc)
2. Intel oneAPI DPC++/C++ Compiler (intel-onapi-compilers)
3. AMD Optimizing C/C++ and Fortran Compiler (AOCC)
4. NVIDIA HPC SDK (nvhpc)

Compiling "Hello World" Program

C

Simple hello.c file that reads

#include <stdio.h>

int main(void){
    printf("Hello, world!\n");
    return 0;
}

can be compiled on Palmetto using the following commands

Compiler	Module	Command
GCC	gcc/12.3.0	gcc hello.c -o hello.x
Intel	intel-oneapi-compilers/2024.0.2	icx hello.c -o hello.x
AOCC	aocc/4.1.0	clang hello.c -o hello.x
NVHPC	nvhpc/23.11	nvcc hello.c -o hello.x

C++

The same example in C++ put in a file hello.cpp

#include <iostream>

int main()
{
    std::cout << "Hello, world!" << std::endl;
    return 0;
}

can be compiled on Palmetto using the following commands

Compiler	Module	Command
GCC	gcc/12.3.0	g++ hello.cpp -o hello.x
Intel	intel-oneapi-compilers/2024.0.2	icpx hello.cpp -o hello.x
AOCC	aocc/4.1.0	clang++ hello.cpp -o hello.x
NVHPC	nvhpc/23.11	nvc++ hello.cpp -o hello.x

FORTRAN

To compile a simple FORTRAN program test.f90

program test
  print *,'hello from fortran'
end program test

use a command appropriate for a given compiler suite

Compiler	Module	Command
GCC	gcc/12.3.0	gfortran test.f90 -o hello.x
Intel	intel-oneapi-compilers/2024.0.2	ifx test.f90 -o hello.x
AOCC	aocc/4.1.0	flang test.f90 -o hello.x
NVHPC	nvhpc/23.11	nvfortran test.f90 -o hello.x
