Thanks Jeff, I know it depends and I want to know exactly what is the dependency and general complexity analysis. Is it really no documentation at all ? For example you said "to be replaced soon", then what is the algorithms that will be used to replace ? Is there any publication available ? In a

Dear all, Where could I find a detailed documentation about algorithms that has been using in Open MPI ? For example, I would like to answer following questions: how MPI_Algather operation is done? what is the complexity in term of the number of data send/receive given a number of node involved?
