Hi Lorenzo,

you can't scale well to 4 cores because your CPU only has two cores. The two additional ones are only hyperthreads. Please repeat the same numerical experiment on a machine with more cores.

Can you please post the complete output for the run with 4 cores? Plus the initial vtk files? And, pretty please with sugar on top, the number of physical cores on your machine?


Good morning,

I enclose the requested files for the sequential (1 processor) and parallel (4 processors) simulations plus some detail on my machine.

Thanks for help,

Lorenzo
