Updates and Upgrades in HPC
What is the difference between an update and an upgrade? We’ll look at why, once an HPC distribution is installed, you are likely to see one or two minor release updates, but rarely an upgrade.
Warewulf 4 – Python and Jupyter Notebooks
Interactive HPC applications written in languages such as Python play a very important part today in high-performance computing. We look at how to run Python and Jupyter notebooks on a Warewulf 4 cluster.
Warewulf 4 – Environment Modules
Environment Modules are an indispensable tool for high-performance computing that allow you to switch between and among versions of compilers, libraries, and applications.
Warewulf 4 – Time and Resource Management
Warewulf installed with a compute node is not really an HPC cluster; you need to ensure precise time keeping and add a resource manager.
Analyzing Logs
Log analysis can be used to great effect in HPC systems. We present an overview of the current log analysis technologies.
Log Management
One of the more mundane, perhaps boring, but necessary administration tasks is checking system logs – the source of knowledge or intelligence of what is happening in the cluster.
Parallel I/O Chases Amdahl Away
Scalability abhors serial computation, but parallel I/O can defeat those limitations.
