Parallel computation [back]

We have now received reports back from JCGS for our parallel MCMC paper and they all are very nice and supportive! The reviewers essentially all like the Rao-Blackwellisation concept we developed in the paper and ask for additions towards a more concrete feeling for the practical consequences of the method. We should thus be able to manage a revision in the coming week or so. Especially because we have had further ideas about the extension of the method to regular Metropolis-Hastings algorithms like the random walk avatar. (The above picture is completely unrelated with the paper, but conveys some feeling of parallelism. I made it [in R] for the poster of the O’Bayes 03 meeting I organised in Aussois in 2003.)

    Hello. I was wondering if you could publish the R code or C++ code that you used to write this parallel MCMC algorithm. I would really love to see how to implement this on some of my Bayesian problems in Political Science. Please let me know if the code is available.
