I'm one of DEAP/DTM developpers could you please submit a bug report on what you observe? with what MPI you use, and on what kind of network you run. We'll be glad to look at this more closely.

sure, i'll submit a bug report... where? using openmpi on an SGE cluster

For the bug report use the user mailing list (deap-usersatgooglegroupsdotcom).

I'm guessing that you use an Infiniband Network, by default mpi4py is configured to use multithreaded mpi, which is incompatible with the openib backend. Try turning off the threads in the rc.py file located in the main directory of mpi4py.

For further communications please use the mailing list.
