Virtual vs pysical core example

Let's make a sample calculation

Let's take a SimpleFoam flow case with around 4 million cells and compare decomposing to virtual and physical cores. The case takes about 5000 iterations to converge. In one case we start a 8 vCPU machine and decompose it to all 8 virtual cores. In a second case we start a 16 vCPU machine and decompose our case to the 8 underlying physical cores.

This will result in the following times and costs:
