Create Module 0 (basic training on relevant subset of C++ preceding Kokkos tutorial Modules 1 onward)

[omsai]

The checklist for suggested revisions contains:

• People in parenthesis who weighed in on the discussion during the Education and Training working group meetings and are potential contributors for the suggested change. Items are pulled from the following meetings of the working group:
  • 2026-03-11
  • 2026-06-16 (this link 2026-06-16 will work after Meeting notes for WG Education and Training development#65 is merged)
• When making changes, refer to the latest PDF built from CI (does not exist yet!)

• Broadly outline both parts of modern C++ that are useful to train on and those not compatible with concurrency:
  • Standard C++ containers are almost impossible to use in a safe and canonical way with Kokkos concurrency (Christian).
    • If possible, highlight these pitfalls.
  • Cover compatible concepts: Ranges, requires clauses, how to build overload sets, basics of for loops, constructors, temporaries, references (Christian).
    • Extend and clean up this list as the module develops.
    • Lower the barrier to entry for new users (Christian).
• Review existing teaching materials and lesson plans:
  • HPSF 2026 talks (Pariksheet)
    • From Fortran
    • From Python / R using Rosetta code and Carpentries-style workshops
    • HPC foundational topics (relevant to Kokkos: build systems, debugging, profiling, C++, etc.)
  • ISO-C++ training group (Christian)
  • Patrick's textbook (ISBN 9783031543692) he used to teach mathematicians C++17/20 (Pariksheet).
  • TODO: Add others?
• For each tutorial module analyze assumed knowledge of C++ and related HPC foundational topics:
  • TODO: Module 1
  • Module 2
    • Reference semantics: copy-by-reference, copy-by-value
    • lambda syntax, including [=] copy-by-value
    • HPC foundational topic of separate memory on CPU and GPU
    • Pointers: shared_ptr, reference counting, pointers to fixed-size arrays, pointers to multidimensional arrays, nullptr
    • Class templates
    • Class constructors and constructor overloading
    • Class operator overloading for assignment
    • Preprocessor operations: static_assert (vs. runtime assert)
  • [...]
