I just wanted to share a little bit of information that both boggled my mind and made me very happy.
Today I ran a Monte-Carlo simulation of my own design; it generated exactly 1 000 000 000 (one billion) random numbers, and took five hours to process on four CPU cores. The simulation produced forty thousand datapoints, which crashed Excel.
To clearly view the resultant graph (using a measly 20 000 of those points), the graph needs to be the size of the computer screen; it is absolutely spectacular. Even with just the outlines of the points, as thin as is allowed, and on 90% transparency, the centre of the graph is completely opaque.
