<blockquote class="gmail_quote" style="margin:0 0 0 .8ex;border-left:1px #ccc solid;padding-left:1ex;">Ok : then this explains why you have 30 replicas.<br>
The goal is to tune number of procs/replica and total number of mpi procs, in order to have a number of replicas = (or smaller, NEVER larger!!!) to the number of images.<br>
