Cluster Toga is a Young Brothers Wait Concept (YBWC) parallelized version of Toga based on Fruit capable to run on a high performance cluster and participated for example in the 17th International Paderborn Computer Chess Championship (IPCCC) 2007 and the 16th World Computer-Chess Championship (WCCC) 2008 in Beijing. In fact Cluster Toga is a stand alone base engine of the GridChess system which participated for example in the 15th World Computer-Chess Championship (WCCC) 2007 in Amsterdam but is limited to use a single cluster. Up to now Cluster Toga has been tested under several Linux derivatives, Windows Server 2003 Compute Cluster Edition and Windows Clusters built from COTS (commodity off-the-shelf) components. If you are interested, a short description about my project and how to receive the source code can be found at

Have fun!

Here is what I have found running on one machine with 4 CPUs and utililizing MPICH2 software. It scales well to 3 processors in such a circumstance and the last one is wasted. It is the same for SMP Scorpio, so perhaps it is a fundamental property of MPI interface. Due to this behavior, I suggest that running on single core machines might be a bit of a problem for scaling, but I did not bother to test that yet.

Hi Dann,

MPI allows you to overload a machine, so try -n 5 on the 4 proc machine.

I don't know exactly how they implemented their systems, but one process could be set up as a manager. The problem I've seen with Open MPI (not OpenMP) is that MPI_Recv is implemented as a busy loop, thus the manager processes burns CPU time when waiting on a Recv. It is possible that MPICH is not set up that way.
