    Compiling CUDA Codes for Nvidia GPU

nvcc $PWD/source_code.cu -o $PWD/exe_code (CUDA code)

Compiling MPI Codes using Intel Compiler

Source the setvars.sh script to set the proper environment variables for the Intel MPI Library

source /opt/intel/oneapi/setvars.sh

Check the Intel MPI Compiler Commands

mpiicx $PWD/myprog.c -o $PWD/myprog (C code)

mpiicpx $PWD/myprog.cpp -o $PWD/myprog (C++ code)

mpiicpx -qopenmp $PWD/myprog.cpp -o $PWD/myprog (C++ /openMP)

Compiling options:

• -o <file>: place the output into <file>. If this option is omitted, the compiler will create executable program named a.out in working directory.
• $PWD: current path.
• -O: compile program with optimization
• -qopenmp: Used for compiling openmp code on Intel Compilers
• -fopenmp: Used for compiling openmp code on GNU Compilers
