Hi, all: I'm trying to use MPI_IBCAST (the non-blocking version) instead of MPI_BCAST for MPI broadcasting . However I got a link error of unresolved external symbol for MPi_IBCAST. I put cxx.lib, mpi.lib, fmpich2.lib and fmpich2g.lib in the linker input list. Does MPICH2 implement MPI_IBCAST? If so, which library shall I use to access it? I'm using the binary package from Jayesh Krishna<mailto:[email protected]> on a 64-bit Windows 7 PC. It's based on mpich2 1.4.1p1. Thanks, Jianhua(John) Jiang _______________________________________________ discuss mailing list [email protected] To manage subscription options or unsubscribe: https://lists.mpich.org/mailman/listinfo/discuss
