Nek5000/nekRS: v22.0

What is new? Multi-session (uncoupled) support Support unaligned symmetry boundary condition Support (unaligned) traction boundary condition Better performance on AMD MI-GPUs FLOP counters Various bug fixes Good to know OpenCL support is now disabled by default Breaking Changes [udf] Rename udfBuildKernel => oudfBuildKernel [par] Separate details of coarse grid discretization from coarse grid solver e.g., `coarseSolver = SEMFEM+AmgX` is replaced by `coarseSolver = AmgX` and `coarseGridDiscretization = SEMFEM` [par] Remove preconditioner=semg and preconditioner=semg_amg [udf] Rename plug-in name avg => tavg [udf] Rename udf.converged => udf.timeStepConverged [nrsconfig] Rename env-var AMGX_ENABLE => ENABLE_AMGX Known Bugs / Restrictions Mesh solver does not support CHT and unaligned sym/shl BCs 729 300 258 Thanks to our Contributors @tcew, @kris-rowe, @aprilnovak We are grateful to all who added new features, filed issues or helped resolve them, asked and answered questions, and were part of inspiring discussions. A special shout out to Tim Warburton at VT for tuning some critical kernels
