Currently the petsc-based solver is only needed for conservative projection which requires MeshFields. So petsc is only linked when PCMS_ENABLE_PETSC and PCMS_ENABLE_MESHFIELDS
Add a shared, format-agnostic GID-to-local permutation and use it so the transfer operators handle sparse or reordered global IDs correctly. This allows us to reuse the global-to-local mapping for things outside of the serialization such as setting up the petsc arrays.
…olders Split the GID (layout) message from the field (data) message and reuse the field GID-permutation primitives so exchanges handle overlap masks and reordered global IDs without corrupting payloads.
The python pcms module links libpetsc.so dynamically when python_api is ON, so PETSc lib dir must be on LD_LIBRARY_PATH for import to succeed.
clang-tidy bugprone-implicit-widening-of-multiplication-result (treated as error) flagged int*int products used to size 64-bit Views in the intersection/MC RHS integrators and the field-exchange-planner test. Perform the multiplication in size_t via an explicit cast.
Forward-declare the RHS integrators
We had kokkos lambdas in private functions which does not compile.
First pass is to just make a host mirror. Long term, we need to ask PETSc team if there is a better way to handle this.
The idea is as follows: a function space creates a function. A Function<T> represents an object that can be evaluated. A Function<T> is a Field<T>. A Field<T> itself does not have evaluation capabilities, but has everything needed to be sent over the network.
naming model, removing AddLayout. Our goal was to remove the need for AddLayout and forcing the user to *know* what layouts they needed to add. This was the simplest strategy of the ones we tested. It also aligns to the idea that fields are likely to have names anyways. So, having a field and layout both have names allows convenient cacheing of the layout communicator and naming of fields that follows on its construction.
With Function<T> being the object that handles evaluatable fields and Field<T> being the non-evaluatable object that can be used for sending over the network. This commit makes the function naming/usage consisent.
