This from the homepage

Lower initial replication and quorum: With the release of the SIMAP applications 5.10 and 5.11 the error results have been drastically reduced. We are very happy about this and would like to thank all participants for the recently increased power of our project (more than 5 TLOPS now!). It is now safe for the scientific parts of BOINCSIMAP to switch back to a minimal quorum of 2 and an initial replication of 2 as we used when BOINCSIMAP started. Recently we have decreased the initial replication to 3. To address the inhomogeneously claimed credits we will switch to fixed credits per workunit that will be determined by the number of sequences in the workunit and the number of hits in the result. We will test this system first with the second application hmmer which is about to start and then apply this to the simap app too (and decrease the quorum to 2). Please use our message boards to discuss the fixed credits per WU. We are interested in your opinion about this.

I think this is a step in the correct direction, It will be interesting to see how this will affect the credits.

With optimized BOINC client this might reduce the amount of credits per WU, while increasing credits per WU for those not using the optimized BOINC apps.

It should also even out the differences I have seen between AMD and Intel based processors. AMD has always done better on this project than Intel, and since most of my crunchers are Intel based it will be interesting to see what happens.

Any idea when this will be released into production ?

Hopefully in 2 weeks. Our schedule is to launch the hmmer app first, see how the fixed credits work for it and apply them then to the simap app.

Best regards

hmmer tests starting: Currently we are running tests with our new hmmer application based on a few workunits. So be not surprised if the hmmer app appears on your workstation. Large scale alpha tests will follow soon.

The hmmer application is an additional application which extends the SIMAP contents. The simap application compares proteins by their similarity. The results are stored in the SIMAP database and are used by scientists using Web pages, Web services or locally installed programs on our servers.

The hmmer application extends this concept to "protein domains". Those domains are mathematical models that describe the functionally relevant and unique parts of proteins. The type of model we are using is called "Hidden Markov Model" (short HMM). The HMMs are the most powerful technique to mathematically describe protein domains and store them into databases. Using the hmmer application we want to compare all known proteins with all protein domain models in several domain databases, in order to find functionalities of proteins. This data is very useful to predict the functions of the proteins - a result that many biologists are extremely interested in.
