- A C++ MPI code for 2D unstructured halo exchange
- Essential bash customizations: prompt, ls, aliases, and history date
- Script to copy a directory path in memory in Bash terminal
- What is the difference between .bashrc, .bash_profile, and .profile?
- A C++ MPI code for 2D arbitrary-thickness halo exchange with sparse blocks
