Without knowing your code I can only guess the problem, but I have two hypotheses: a) If those arrays are dynamically allocated via "new", then you cannot send multiple objects using the same MPI datatype as the offset of the array content to the containing object will vary between multiple instances. b) A frequent error when using vectors is the assumption that the address of the first element can be obtained by "&vector" (works almost never) or "&vector.begin()" (works for some implementations). The correct method would be "&vector[0]" or "&vector.front()". You could get more detailed feedback if you would attach a minimal excerpt of your code that reproduces the error (and still constitutes a valid/complete MPI program).
