Release - version 0.12.0

[jeremylt]

Draft release notes:

New features

-Added Sycl backends /gpu/sycl/ref, /gpu/sycl/shared, and /gpu/sycl/gen.

• Added support for application codes which manage multiple Ceed objects, parallelized across OpenMP threads.
• Update CeedOperatorLinearAssembleDiagonal to provide default implementation that supports CeedOperator with multiple active bases.
• Added CeedOperatorLinearAssemblePointBlockDiagonalSymbolic to create COO mapping for mapping out of {c:func}CeedOperatorLinearAssemblePointBlockDiagonal.
• Added CeedBasisApplyAtPoints and CeedElemRestriction[Create, Apply]AtPoints for evaluation of FE bases at arbitrary locations, such as material points.
• Added support for non-tensor H(div) finite element spaces with CeedBasisCreateHdiv and CeedElemRestrictionCreateOriented
• Added support for non-tensor H(curl) finite element spaces with CeedBasisCreateHcurl and CeedElemRestrictionCreateCurlOriented
• Update /cpu/self/memcheck/* backends to help verify CeedVector array access assumptions and CeedQFunction user output assumptions.

Interface changes

• Update CeedOperatorContext* functions to CeedOperator*Context* functions for consistency.
• Removed CeedBasisSetNumQuadraturePoints as redundant and bug-prone interface.
• Update CEED_BASIS_COLLOCATED to CEED_BASIS_NONE for clarity.

Examples

• Require PETSc version 3.20 or later.
• Add DMSwarm example demonstrating interpolation from background mesh to swarm points and projection from swarm points to background mesh.

Fluid Dynamics Example

• Updated restart and checkpointing interface.
• Add data-driven subgrid-stress model.
• Add differential filtering of solution.
• Add turbulence statistics collection over spanwise-symmetric geometries.
• Add Taylor-Green vortex initial condition.
• Add Riemann-based outflow boundary conditions.
• Added vortex shedding and flow past cylinder example, including calculations for lift, drag, and heat transfer.
• Add Internal Damping Layer (IDL) for helping turbulent simulation stability.
• Derive CeedBasis from PetscFE, and various other internal maintainability updates.

We should mention particles, right? #1284 has v0.12 as its milestone. (EDIT: That's what *AtPoints does, but we could mention the new example.)

@jrwrigh What should we mention about fluids here? Do you still want to merge #1203?

Yeah, I was waiting to make sure that we updated CI and merged that MR before adding it to the release notes, but it should be added to that list once that happens.

Do you still want to merge #1203?

I don't want to rush that PR or hold back the release. So if it happens, great. If it doesn't, oh well. I'm not sure anyone interested in using that PR is particularly bound to specific releases anyways (though I could be wrong about that).

[jrwrigh]

I've done a quick double-check for the Sycl backends on Sunspot and confirmed they're all good-to-go

@jrwrigh What should we mention about fluids here?

For fluids:

• Added vortex shedding example (Vortex shedding / flow past cylinder  #1082), including calculations for lift, drag, and heat transfer (Lift, Drag, Heat Transfer #1130)
• Updated restart and checkpointing interface (fluids: checkpoint interval #1131)
• Added partitioning statistics to the standard output (fluids: Add partition statistics to standard output #1247)
• Add Riemann-based outflow boundary conditions (Switch outflow from pressure to Riemann pressure + temperature #1133 )
• Add turbulence statistics collection over spanwise-symmetric geometries (fluids: Spanwise Statistics Collection #1135)
• Add Internal Damping Layer (IDL) for helping turbulent simulation stability (Ken/idl #1138)
• Add MatopApplyContext structs
• Add PetscLogEvents for CeedOperator functions (Apply, Assemble, etc.)
• Compatability with 64-bit PetscInts (fluids: Compatability for PETSc w/ 64bit ints #1234)
• Determine CeedBasis from PetscFE, making simplex elements possible (PetscFE determines basis for examples/fluids/navierstokes #1264)
• Minimum PETSc version bumped to 3.19
• Add data-driven subgrid-stress model (fluids: Data-driven SGS modeling #1149)
• Add differential filtering of solution (fluids: Add differential filtering capability #1189)
• Refactor platemesh flags
• Add Taylor-Green vortex initial condition
• Add address sanitizer build support

Other things to be added to release notes

• We also added gpu/sycl/gen
• Probably also add in the OpenMP work that got merged in recently?

Made some updates per the comments above

Consider mentioning movement of gravity/conservative body force from E_tot (fifth conservation variable) to rate if work done by body force (rho u . b). #1371
