OpenMP threading in MPAS-Ocean
...
Requirements
Requirement: bit-for-bit

Regardless of whether decomposition is flat MPI or hybrid MPI/OpenMP, simulation results are bit-for-bit identical.
Algorithmic Formulations
Design solution: element-based OpenMP

After scoping and prototyping several different approaches, the algorithmic approach will employ loop-by-loop OpenMP directives.
Design and Implementation

This section should detail the plan for implementing the design solution for requirement XXX. In general, this section is software-centric with a focus on software implementation. Pseudo code is appropriate in this section. Links to actual source code are appropriate. Project management items, such as svn branches, timelines and staffing are also appropriate. How do we typeset pseudo code?
Planned Verification and Unit Testing

Since we require bit-for-bit, verification is straightforward. We will verify bit-for-bit across the full suite of MPAS-Ocean test cases.

Since we require bit-for-bit, validation is not a part of this process.
Planned Performance Testing

Performance evaluation will be carried out on (at a minimum) Edison and Mira. On both platforms, we will evaluate performance across a broad range of thread-per-MPI task. An example of our testing can be found in the file below. This testing will be conducted again at completion of the implementation.
