Hello. I'm an Ookami HPC user and I'm trying to optimize OpenFOAM based on benchmarks from Fugaku.
In your repo, DICPreconditioner.C is patched to improve performance. However, after patching the code, I found there's essentially no difference between your improved DIC algorithm and the FDIC algorithm (https://develop.openfoam.com/Development/openfoam/-/blob/master/src/OpenFOAM/matrices/lduMatrix/preconditioners/FDICPreconditioner/FDICPreconditioner.C)
DICPreconditioner.C
Which means that DIC doesn't need to be patched at all. All you need to do is specifying "FDIC" in fvSolutions.
