I have tried dividing the probability distribution function into codistributed 1D matrices inside the spmd block. However, the parallelised code runs slower than the serial code. I believe that I am doing it incorrectly. Please provide relevant study material and codes that might be of some help.
Before the start in your project, the first thing you need to is Applied Linear Algebra and Calculus. Learning the fundamental mathematical concepts may need some time, but once you got such concepts; it will be a driving force for your future learning academic journey.
Dear Mathias J. Krause
Can you please elaborate on how to do it or provide some documentation?
Regards

In Matlab/Octave:
A directly: Write the LB algorithm in a parallelizable way, e.g. as in Article An Auto-Vectorization Friendly Parallel Lattice Boltzmann St...
and then use e.g. parfor of pct.B with OpenLB: By writing a function cf. https://de.mathworks.com/help/matlab/matlab_external/call-matlab-functions-from-c-1.html
