Pseudo Code continued… For each processor { –MPI_Recv the new particles Meanwhile… –Each processor is outputting the coordinate information to separate files –Processor 0 holds the photobleaching region and outputs the number of particles inside at each time step Area of photobleaching region / total Area * total number of particles could give a good estimate of the number of particles in the region at any given time This number is ~ 980 particles we can see that this is not the case I will play around with the PDF to see what kind of numbers I can get…
