Overall, this page serves as a valuable resource for anyone interested in gaining knowledge about the primary software landscape within Shabyt and learning how to engage with these tools efficiently.

Environment Modules

Shabyt uses Environment modules to dynamically set up environments for different software. Module commands set, change, or delete environment variables that are needed for a particular software. The ‘module load‘ command will set PATH, LD_LIBRARY_PATH and other environment variables such that user may choose a desired version of applications or libraries more easily. More details can be found here.

Environment module commands

Command	Description
module avail	List of available software
module keyword [word]	Search for available modules matching the keyword
module spider [word]	Show the details of any modules matching the keyword
module whatis [module]	Show the short description about module
module load [package1] [package2]	Load the environment for the default version of the modulefile
module load [package]/[version]	Load the environment for the specified version of module
module unload [package1] [package2]	Unload previously loaded packages
module swap [moduleA] [moduleB]	Unload modulefile A and load modulefile B
module list	List any currently loaded module(s)
module purge	Unload all currently loaded modules

Anaconda

Description: "Anaconda" (shortly "conda"), a Python package management, which helps you create an environment for many different versions of Python and package versions. Anaconda is also used to install, remove, and upgrade packages in your project environments.

Usage: module load Anaconda3/2022.05

Ansys

Description: The ANSYS suite of tools can be used to numerically simulate a wide range of structural and fluid dynamics issues encountered in several engineering, physics, medical, aerospace, and automotive sector applications.

Usage: Loading the ANSYS module module load ansys/2022r1 Launching the workbench is accomplished by: runwb2 The workbench provides access to Fluent, CFX, ICEM, Mechanical APDL/model, and many other languages and models. The appropriate GUIs can be launched outside of the workbench using fluent, cfx5pre, icemcfd, and launcher.

CUDA

Description: Nvidia created the parallel computing platform and programming model known as CUDA for use with its GPUs for general computing (graphics processing units). By utilizing the capability of GPUs for the parallelizable portion of the calculation, CUDA enables developers to accelerate computationally heavy applications.

Usage: module load CUDA/11.4.1 To check if CUDA has been loaded, type: nvcc --version

GCC

The GNU Compiler Collection, commonly known as GCC, is a set of compilers and development tools available for Linux, Windows, various BSDs, and a wide assortment of other operating systems. It includes support primarily for C and C++ and includes Objective-C, Ada, Go, Fortran, and D. The Free Software Foundation (FSF) wrote GCC and released it as completely free (as in libre) software.

GCC is a toolchain that compiles code, links it with any library dependencies, converts that code to assembly, and then prepares executable files. It follows the standard UNIX design philosophy of using simple tools that perform individual tasks well. The GCC development suite utilizes these discrete tools to compile software.

When you run GCC on a source code file, it first uses a preprocessor to include header files and discard comments. Next, it tokenizes the code, expands macros, detects any compile-time issues, then prepares it for compilation. It is then sent to the compiler, which creates syntax trees of the program’s objects and control flow and uses those to generate assembly code. The assembler then converts this code into the binary executable format of the system. Finally, the linker includes references to any external libraries as needed. The finished product is then executable on the target system.

GCC examples

Compiling a program with GCC can be a straightforward matter/

gcc hello.c -o hello

Running this command processes the hello.c file and generates a binary called “hello”. Additional parameters can be passed.

gcc hello.c -O3 -o hello

In this example, the optimization parameter is set to 3, leading to more optimized code generation. Additional libraries can be included as well.

gcc hello.c -lncurses -o hello

This example includes the ncurses library.

More complex compilations are managed by Makefiles and are invoked with the “make” command.

GROMACS

Description: GROMACS is a flexible package for performing molecular dynamics, simulating the Newtonian equations of motion for systems containing hundreds of thousands to millions of particles. It is intended for biochemical molecules, such as proteins, lipids, and nucleic acids, with complex bonded interactions. However, GROMACS is fast at calculating nonbonded interactions, so many groups use it for non-biological systems, like polymers.

Usage: To load GROMACS software: module load GROMACS/2021.5-foss-2021b-CUDA-11.4.1 The GROMACS executable is either gmx or gmx mpi if an OpenMPI module is used. When you type gmx help commands, a list of gmx commands and their functions will be displayed.

Batch jobs: Users are encouraged to create their own scripts for batch submissions. Below are examples of batch submission scripts.
