Re: [OMPI users] MPI_Allreduce fail (minGW gfortran + OpenMPI 1.6.1)

can be used by just extracting. If you compile my little code with MinGW gfortran, then you'll see the program abort. I have no idea of checking it. It probably a windows related error, since MinGW has nothing to do with POSIX. That's what I can tell so far. Any suggestions? Yonghui

[OMPI users] MPI_Allreduce fail (minGW gfortran + OpenMPI 1.6.1)

.lib The MPI_Allreduce fail. [xxx:02112] [[17193,0],0]-[[17193,1],0] mca_oob_tcp_msg_recv: readv failed: Unknown error (108). I am not sure why this happens. But I think it is the windows build MPI problem. Since the simple code works on a Linux system with gfortran. Any ideas? I appreciate any response! Yonghui
