Hi,

In most of my simulations I use 1 thread/core and find it the most
optimal solution. Also it helps to get completely identical results
excluding openmp-instability. And only on a very large simulations
(>10^5 particles) it is reasonable to use 2-3 threads, no more.

So, I personally agree.

Anton
