Is there an efficient way to debug an MPI master-worker model without parallel debugger?
Hereby I have a master-worker model, where the one and only master start a MPI_Comm workercomm and all the workers are spawned by MPI_Comm_spawn in it. Of course in the first run some bugs exists and debug tools are needed.
