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.

`diff` Also Compares Directories

Short post so that I can remember this everytime I need to do something similar!

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.
