We are witnessing a denial of service attack on the US government by its Supreme Court. Nothing about this is okay or acceptable.

@powersoffour There may already be published DFDL descriptions for many formats of interest. See https://en.wikipedia.org/wiki/Data_Format_Description_Language?wprov=sfti1 and https://github.com/DFDLSchemas for starting points.

  Data Format Description Language
  
  Data Format Description Language (DFDL, often pronounced daff-o-dil) is a modeling language for describing general text and binary data in a standard way. It was published as an Open Grid Forum Recommendation in February 2021, and in April 2024 was published as an ISO standard. A DFDL model or schema allows any text or binary data to be read (or "parsed") from its native format and to be presented as an instance of an information set. (An information set is a logical representation of the data contents, independent of the physical format. For example, two records could be in different formats, because one has fixed-length fields and the other uses delimiters, but they could contain exactly the same data, and would both be represented by the same information set). The same DFDL schema also allows data to be taken from an instance of an information set and written out (or "serialized") to its native format. DFDL is descriptive and not prescriptive. DFDL is not a data format, nor does it impose the use of any particular data format. Instead it provides a standard way of describing many different kinds of data formats. This approach...

Here's our latest training/outreach cluster based on Radxa X2L SBCs
4 nodes of quad-core X86 Celeron
8 GB memory/node
PoE local power control through switch
Rocky 9.3 OS
Warewulf 4.5 for node provisioning
We’ll soon add (as on our other ones already built and to come) Slurm, Spack, and a suite of HPC applications
Head node has 2TB of NVMe storage nfs mounted to the worker nodes, which are diskless and stateless
Total cost about $700 (full parts list and accounting to come)
Note the carry handle!
