[mpich-discuss] Any application using mpi_barrier a lot?

[Shanyuan Gao]

My current research is trying to rewrite some collective MPI  
operations to work with our system.  Barrier is my first step, maybe  
I will have bcast and reduce in the future.  I have done some  
synthetic tests.  Now I want a real application to measure the  
performance improvement versus normal MPI_Barrier.  And the  
improvement can only be measured if the barriers are executed many  
times.  If you know any, please let me know.  Any comment are  
welcomed, thanks!
