An Update To Apptainer Use On TACC HPC
The University of Texas’ newest supercomputer Frontera currently requires the following modules loaded for Apptainer images/containers based on the mvapich infiniband (ib) base images–particularly for any containerized programs that intend to use MPI. Researchers moving their Apptainer images between TACC HPC systems, or building container images specifically for individual systems, may need to adapt their sbatch scripts to accommodate differences between default environments and infrastructures on the various available clusters.

Reproducible Scientific Python Using Containers
Use Microsoft’s VSCode editor (code), Docker Containers, and other open-source tools for scientific Python software collaboration, development, and use on Linux and Windows. Securely connect offices, remote workers, storage resources, compute resources, and the cloud with Tailscale as a replacement for traditional VPN. System Packages VSCode Editor Download Visual Studio Code from Microsoft. For a Debian-based GNU/Linux distribution like Ubuntu or Pop OS, the .deb can be installed with sudo dpkg -i code_$version_amd64.deb.

`diff` Also Compares Directories
Short post so that I can remember this everytime I need to do something similar! Using diff on more than individual files The quick and dirty explaination is that the GNU/Linux diff command has an -r flag to recursively compare two folders. The command help indicates that it is shorthand for the full --recursive flag, which might be easier to remember. diff --help # ... -r, --recursive recursively compare any subdirectories found # ... Example In the following example, “Only in” shows that particular files are only found in one of the folders. By default, matching files are not shown. If a file can be found in both folders and the two versions differ, the normal diff output is provided along with the modified times. All together these details provide a good summary of what a user might want to know when comparing two directories.
