One of the projects I've supported for a long time, the Muon1 DPAD, has hit 20 Quadrillion particle-timesteps (pts). Thats a 2, with 16 zeros (20,000,000,000,000,000), or two million-billion. A particle timestep is simulating a particle for 0.01 nanoseconds (0.00000000001 second). I've been invovled with the project since around 2003, and as of writing this, I'm 362 overall, having done 5,867,002,100,000 pts, or 0.0293% of the total work.
