Hi I am trying to compile a code that was done for MPICH2 to openmpi 1.1, and I am getting a warning:
warning: passing argument 3 of ‘MPI_Irecv’ makes pointer from integer without a cast MPI_Irecv takes the third parameter (the buffer type) as integer (MPI_Datatype), and I am using constants declared with (#define) and these used to work fine with me on MPICH2. Are the MPI APIs interfaces different in open-mpi? if so, where can I get this reference? I am afraid I might be wrong about something else, thanks again, Manal
