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? what is the data structure behind ?. Same as for MPI_Alreduce etc.. Is this information available to access and how can I access it ? I know there is one way which is digging into the source code, but I hope there is a easier way to achieve the same goal. Many Thanks, Vu.
