What Optimizations can I do to reduce the runtime without effecting the correctness of the numerical values of a solved case?
Where are places I need to look into? What should I be changing and consider making changes to? |

I am sorry. It is a case run in OpenFOAM which is written in C.
Software used: OpenFOAM CFD Case: I am trying to solve the Shallow Water Equations using the OpenFOAM built in solver shallowWaterFoam. Grid size: 70 x 40 square meters. Iv started with a fine mesh with 20 cells per meter and have reduced it to 5 cells per meter for run-time reduction. Reducing it further may affect the accuracy of the output!!! Current Hardware: Intel Core i7-3770 ---> 3.4 Ghz x 8 Graphics: Gallium 0.4 on NVE7 Cache: 3MB Can you suggest some best choices for profiling packages? Thanks |
