Weekly fys3150/4150 update

Hi all, we hope the week started the best possible way!

Last week we discussed in detail project 4 but we scratched only the surface of the Metropolis algorithm and the mathematics of random walks, Markov chains etc. Thursday we will derive the Metropolis algorithm (chapter 12 of the lecture notes) and end our discussion of project 4 on Friday. On Friday we will go back to a discussion of random number generators and also discuss properties of random numbers and statistical variables. This will lead us to a better understanding of errors in our calculations. This material is covered by chapter 11. 

Else, at the lab, for all sessions (except Friday at 1415 due to a PhD defense) we will discuss how to parallelize the Ising model. We will do some live programming there and write our first program using MPI and OpenMP.  The material is covered by the lecture slides in

http://compphysics.github.io/ComputationalPhysics/doc/pub/codeoptimization/html/codeoptimization-bs.html. For project 4, to parallelize your code allows you to produce more data for the final statistical analysis. 

Note also that there is a change room Thursday, we will use Lille Fysiske auditorium for our 815-10 lecture. On Friday we are back to store fysiske aud.

Best wishes to you all,

Morten et al
