Dearall I haveimplemented the following two algorithms on my home Ethernet LAN containing 2/and three heterogeneous devices using MPICH2. Algorithm1: 1- Rootprocess reads the contents of an input array. 2- Itthen sends the array data to all other processes. 3- Allprocesses including the root process perform specific computations on their array copies. 4- Oncethe computations within each process are finished, the generated arrays are directly written by the process that performed the computations to separate files. Algorithm2: Same asAlgorithm 1 except step 2 is replace by: 2- Root process broadcast the array data to all other processes. Theimplementation of both algorithms work fine and give the expected resultsbut Algorithm2 that uses MIPI_Bcast is slower than Algorithm1 that usesMPI_Send For myknowledge, MIPI_Bcast is faster than MPI_Send. Please,would you guide me to know if there is any conflict of misunderstand. Thanksa lot Alaa _______________________________________________ discuss mailing list [email protected] To manage subscription options or unsubscribe: https://lists.mpich.org/mailman/listinfo/discuss
