Muon version 4.45 is now in operation. The most important change is in it's accuracy. Previous versions have had a slight problem with 'flutter' or noise, meaning results are not always the most accurate. In September/October 2010, a group of users ran a detailed scan, testing a set design with only a single variable changed throughout. It used the (recently discontinued) Linac900Ext10d2 lattice, and changed only one variable, .ls5l. in its full range from 000 to 999. Starting mid-March 2011, a new alpha version was released and the exact same scan was run again, using the new client. The changes in accuracy are quite significant compared with the previous version. Performance wise, little has changed, and the new client crunches about as fast as the previous client, so while there's no gain, neither is there a loss, in compensation for increased accuracy. There is no doubt though, that Muon1 leads the field in 2nd-generation, massive-scale distributed computing. Not only is it one of the few genetic-based projects, it's also one run on almost no resources, while still being not just cutting edge, but bleeding edge. For a much more detailed description of all improements of the native muon1.exe client check the blog.
