Unable to Install hdf5, hdf5-devel and hdf5-static on Rocky Linux 8.7

If you are doing a dnf install on hdf5 packages, you will notice errors like the one below

nothing provides libsz.so.2()(64bit) needed by hdf5-1.10.5-4.el8.x86_64
(try to add '--skip-broken' to skip uninstallable packages or '--nobest' to use not only best candidate packages)

To resolve the issue, you will need to install and enable PowerTools

Step 1: Install DNF plugins package

dnf install dnf-plugins-core

Step 2: Install EPEL

The reason is that some software from its source code requires some dependencies that are available in EPEL

dnf install epel-release

Step 3: Enable PowerTools repository on Rocky Linux 8

dnf config-manager --set-enabled powertools

Step 4: Now try installing HDF5

dnf install hdf5 hdf5-devel hdf5-static

PackagesNotFoundError and Conda Install

If you are installing package with conda and you are encountering an issue.

PackagesNotFoundError: The following packages are not available from current channels:

- c-compiler
- fortran-compiler
- cxx-compiler

There is a workaround below. IThis is important as it tells conda to also look on the conda-forge channel when you search for packages.

conda config --append channels conda-forge

Basic Introduction to Git (Part 2)

Initialising a Repository in an Existing Directory

If you wish to have a project directory under version control with GIt, do the following

$ cd /home/user/my_project
$ git init

If you wish to add existing files into the version control

$ git add *.sh
$ git add LICENSE
$ git commit --m "Gekko Menu Help Application"
[master (root-commit) c98ae91] Gekko Menu Help Application
 1 file changed, 73 insertions(+)
 create mode 100755 mymenu.sh

You have an initial commit and tracked files. Hooray.

Checking the status of your Files

[user1@node1 menu]$ git status
# On branch master
nothing to commit, working directory clean

This means you have a clean working directory; in other words, none of your tracked files are modified.

Adding new files to your Git Directory

Let’s say you added a new file called check_license_abaqus.sh into the Project Directory, you will have something like

# On branch master
# Untracked files:
#   (use "git add <file>..." to include in what will be committed)
#
#       check_license_abaqus.sh
nothing added to commit but untracked files present (use "git add" to track)

To add files

[user1@node1 menu]$ git add check_license_abaqus.sh
[user1@node1 menu]$ git status
# On branch master
# Changes to be committed:
#   (use "git reset HEAD <file>..." to unstage)
#
#       new file:   check_license_abaqus.sh
#

To remove file

[user1@node1 menu]$ git rm check_license_abaqus.sh -f
rm 'check_license_abaqus.sh'
[user1@node1 menu]$ git status
# On branch master
nothing to commit, working directory clean

To see log, you want to use the command

[user1@node1 menu]$ git log
commit xxxxxxxxx
Author: user1 <kmyemail_used_in_Github@hotmail.com>
Date:   Sun Sep 25 23:50:33 2022 +0800

Basic Introduction to GitHub (Part 1)

GitHub is the largest code-hosting platform in the world. It uses Git as version control and the repository is based on GitHub. Features such as Pull Requests, Project Boards and GitHub are central and found in one place.

To start using GitHub, please go to https://github.com/join and follow the instruction

Creating a PAT of SSH Key

A PAT is a string of characters that can be used in place of a password against the GitHub API and on command lone.

You may need to understand the various scopes on GitHub such as repo, admin: repo_hook, users etc. For more information, do take a look at https://docs.github.com/en/developers/apps/building-oauth-apps/scopes-for-oauth-apps#available-scopes

For starters, you may want to go to https://github.com/settings/tokens and click on Generate new token

On Linux, you can generate your SSH key using the email that you have created in your GitHub User Account

[user1@node1 ~]$ ssh-keygen -t rsa -C "myemail_used_in_Github@hotmail.com"
Generating public/private rsa key pair.
Enter file in which to save the key (/home/user1/.ssh/id_rsa):
/home/user1/.ssh/id_rsa already exists.
Overwrite (y/n)? y
Enter passphrase (empty for no passphrase):
Enter same passphrase again:
Your identification has been saved in /home/user1/.ssh/id_rsa.
Your public key has been saved in /home/user1/.ssh/id_rsa.pub.
The key fingerprint is:
........
........

Adding the SSH Key to the ssh-agent

Although this is not mandatory, adding the SSH Key to the SSH Agent is a good practice that will keep the SSH Key safe. The SSH-agent is an SSH Key Manager that helps to keep the SSH key safe because it protects your SSH keys from being exported. The SSH Agent also saves you from having to type the passphrase you create. every time your SSH key is used.

Before you check, you want to check your ~/.ssh/config first

$ vim ~/.ssh/config
Host * 
AddKeysToAgent yes

At the Terminal,

$ ssh-add ~/.ssh/id_rsa

Copy your SSH Public Key to the field. In your ~/.ssh/config, it should have a .pub extension like id_rsa.pub

Configuring Git

To intialise the Git. Do the following. You may want to take a look at

[user1@node1 ~]$ git config --global user.name "Melvin Soh"
[user1@node1 ~]$ git config --global user.email "kittycool@hotmail.sg"
[user1@node1 ~]$ git config --global init.defaultBranch main
[user1@node1 ~]$ git config --list
credential.helper=netrc -f ~/.netrc.gpg -v
user.name=user1
user.email=myemail_used_in_Github@hotmail.com
init.defaultbranch=main

Installing CP2K with Nvidia HPCX on Rocky Linux 8.5

What is HPCX?

NVIDIA® HPC-X® is a comprehensive software package that includes Message Passing Interface (MPI), Symmetrical Hierarchical Memory (SHMEM) and Partitioned Global Address Space (PGAS) communications libraries, and various acceleration packages. For more information, do take a look at https://developer.nvidia.com/networking/hpc-x

What is CP2K?

CP2K is a quantum chemistry and solid state physics software package that can perform atomistic simulations of solid state, liquid, molecular, periodic, material, crystal, and biological systems. CP2K provides a general framework for different modeling methods such as DFT using the mixed Gaussian and plane waves approaches GPW and GAPW. Supported theory levels include DFTB, LDA, GGA, MP2, RPA, semi-empirical methods (AM1, PM3, PM6, RM1, MNDO, …), and classical force fields (AMBER, CHARMM, …). CP2K can do simulations of molecular dynamics, metadynamics, Monte Carlo, Ehrenfest dynamics, vibrational analysis, core level spectroscopy, energy minimisation, and transition state optimization using NEB or dimer method. (Detailed overview of features.). For more information, do take a look at https://www.cp2k.org/

Getting the CP2K

git clone --recursive https://github.com/cp2k/cp2k.git cp2k

Unpack hpcx and Optimised OpenMPI Libraries. For more information on installation, do take a look at Installing and Loading HPC-X

Extract hpcx.tbz into your current working directory.

% tar -xvf hpcx.tbz
% cd hpcx
% export HPCX_HOME=$PWD
% module use $HPCX_HOME/modulefiles
% module load hpcx

Use the CP2K Toolchain to Compile for the easiest

% cd cp2k
% cd /usr/local/software/cp2k/tools/toolchain
% ./install_cp2k_toolchain.sh --no-check-certificate --with-openmpi

Compiling the CP2K

.....
.....
==================== generating arch files ====================

========================== usage =========================
Done!
Now copy:
  cp /usr/local/software/cp2k/tools/toolchain/install/arch/* to the cp2k/arch/ directory
To use the installed tools and libraries and cp2k version
compiled with it you will first need to execute at the prompt:
  source /usr/local/software/cp2k/tools/toolchain/install/setup
To build CP2K you should change directory:
  cd cp2k/
  make -j 80 ARCH=local VERSION="ssmp sdbg psmp pdbg"

Do exactly on the ending instruction

% cp /usr/local/software/cp2k/tools/toolchain/install/arch/* /usr/local/cp2k/arch
% source /usr/local/software/cp2k/tools/toolchain/install/setup
% cd /usr/local/software/cp2k
% make -j 32 ARCH=local VERSION="ssmp sdbg psmp pdbg"

If you encounter an error during making like the one below, just do an install for liblsan

% /usr/bin/ld: cannot find /usr/lib64/liblsan.so.0.0.0
% dnf install liblsan -y

If you encounter error like the ones below for fftw libraries,

/usr/bin/ld: cannot find -lfftw3_mpi
collect2: error: ld returned 1 exit status

You have to go to the supporting package libraries and do some editing.

% cd /usr/local/software/cp2k/tools/toolchain/install/fftw-3.3.10/lib
% ln -s libfftw3.a libfftw3_mpi.a
% ln -s libfftw3.la libfftw3_mpi.la

Try again

% cd /usr/local/software/cp2k
% make -j 32 ARCH=local VERSION="ssmp sdbg psmp pdbg"

If successful, you should see binaries at /usr/local/software/cp2k/exe/local
