HI, In my MPI program, master send many msaages to another worker with the same tag. The worker uses sMPI::COMM_WORLD.Recv(&message_para_to_one_worker, 1, message_para_to_workers_type, 0, downStreamTaskTag); to receive the messages I got error:
n36:94880] *** An error occurred in MPI_Recv[n36:94880] *** on communicator MPI_COMM_WORLD[n36:94880] *** MPI_ERR_TRUNCATE: message truncated[n36:94880] *** MPI_ERRORS_ARE_FATAL (your MPI job will now abort)[n36:94880] *** Process received signal ***[n36:94880] Signal: Segmentation fault (11)[n36:94880] Signal code: Address not mapped (1) Is this (the same tag) the reason for the errors ? ANy help is appreciated. thanks Jack Oct. 31 2010
