Hi, I was issuing an MPI_Bcast in a sample program and was hitting an unknown error; at least that was what MPI was telling me. I traced through the code to find my error and came upon MCA_PML_CM_REQUEST_INIT_COMMON macro function in pml_cm_sendreq.h. I looked at the function and noticed that in this function the elements of req_status were getting initialized; however, req_status.MPI_ERROR was not. I thought that maybe MPI_ERROR must also require initialization because if the value of MPI_ERROR was some arbitrary value not equal to MPI_SUCCESS then my program will definitely die. Unless, MPI_ERROR is propragating from upper layers to signify an error, but I wasn't sure. Anyway, I assumed that MPI_ERROR was not propagating from upper layers, so then I set req_status.MPI_ERROR to MPI_SUCCUSS and reran my test program. My program worked. Now, having gotten my program to work, I thought I should run this by you to make sure that MPI_ERROR was not propagating from upper layers. Is it ok that I did a: "(req_send)->req_base.req_ompi.req_status.MPI_ERROR = MPI_SUCCESS;" in MCA_PML_CM_REQUEST_INIT_COMMON?
Thank You, Sajjad Tabib
