> Hi Cafe,
> I’m glad to inform that the speed of simulation in the aivika [1]
> simulation library of version >= 5.2 has been dramatically increased after
> I started using the mwc-random [2] package for generating random numbers.
> It was possible to use custom random number generators before, but now the
> random number generator from the mentioned package is used by default. To
> improve the speed of simulation, in most cases it will be sufficient just

> In some my tests the speed of simulation has been increased up to 7 times
> when using default settings. The mwc-random package is just fantastic!
> Another good news is that I recently improved the distributed simulation
> module [3], which has recovering capabilities now in case of temporary
> connection errors. It should be quite unusual for the optimistic Time Warp
> method. In short, it means that we can build discrete event distributed
> simulation models using the ordinary Internet and cloud services.
