NEKO v0.7.0

[njansson]

Release Notes

This is a major release, adding several new features and fixes several bugs and portability issues, including:

• Change the format of the case file to JSON (Change case file to json format #886)
• Add a simulation component framework (Simulation component framework #825)
• Add support for probes (Support for history points and/or time series extraction #827, Point interpolator on GPUs (CUDA/HIP) #972)
• Add support for multiple types of source terms (Support for multiple types of source terms #824)

Note: These are breaking changes, older case files (<= 0.6.1) must be converted to JSON.

Furthermore, this release also improves the performance of the accelerator backend by including the task-decomposed pressure preconditioner presented at SC'23 (https://doi.org/10.1145/3581784.3627039). The new preconditioner is enabled by default if Neko is built using OpenMP and GPU-aware MPI.

Known Issues

• Problems with recent Cray Fortran compilers: Corrupt pointers with Cray Fortran/11.0.2 #200
• OpenCL backend limited to a single queue (stream): Invalid event list in device_stream_wait_event #1056
