The formula is evaluated in dependence of n that means the number of nodes and the kernel speedup ksp.
In addition you can use math functions from JavaScript, for example Math.floor().

The formula is evaluated in dependence of n that means the number of nodes and the start of the second phase delta.
In addition you can use math functions from JavaScript, for example Math.pow().

The runtime for the first phase is evaluated without tuning effort.
You may want to adapt the formula in "Parameters for the program".

Formulas

$ \text"productivity" = \text"value"/\text"cost" = {n_{ex}(n, τ)}/{{\text"TCO"(n, τ)} $ with the number of executions $n_{ex}(n, τ) = {α · τ}/{t(n)} $
($n$ being the number of nodes, $τ$ the system lifetime, $α$ the system availability and $t(n)$ the parallel runtime)
