Comspec in Go
This is a prototype compatibility checking tool. Right now our aim is to use in the context of these build matrices for LAMMPS and these prototype specifications that are based off of Proposal C of the Compatibility Working Group. This is experimental because all of that is subject (and likely) to change. This project is under development, and you can see our docs for early documentation.

Limitations
- I'm starting with just Linux. I know there are those "other" platforms, but if it doesn't run on HPC or Kubernetes easily I'm not super interested (ahem, Mac and Windows)!
- not all extractors work in containers (e.g., kernel needs to be on the host)
- The node feature discovery source doesn't provide mapping of socket -> cores, nor does it give details about logical vs. physical CPU.
- We will likely want to add hwloc go bindings, but there is a bug currently.
Note that for development we are using nfd-source that does not require kubernetes:
go get -u github.com/converged-computing/nfd-source/source@0.0.1
There is some bug with installing the traditional way that I can look into later:
github.com/compspec/compspec-go/plugins/extractors/nfd imports
github.com/converged-computing/nfd-source/source: no matching versions for query "latest"
And moving forward we will be working from this WIP branch:
# This is the develop branch
go get -u github.com/converged-computing/nfd-source/source@20d686e64926b80421637e82fb68e6c5f3f9242a
Note that the above is the main branch on February 22, 2024!
TODO
- add descriptions to sections
- make extractor sections into interface
- metadata namespace and exposure: someone writing a spec to create an artifact needs to know the extract namespace (and what is available) for the mapping.
- tests: matrix that has several different flavors of builds, generating compspec json output to validate generation and correctness
- likely we want a common configuration file to take an extraction -> check recipe
- todo thinking around manifest.yaml that has listing of images / artifacts
Extractors wanted / needed
A * indicates required for the work / prototype I want to do
- power usage data valorium
- ... please add more!
