Dear developers of OpenMPI, I found that when building an executable from a Fortran95-code on a LINUX cluster with OpenMPI-1.8.1 (and INTEL-14.0.2 Ftn-compiler) the following two MPI-3 routines do not exist:
/dat/KERNEL/mpi3_sharedmem.f90:176: undefined reference to `mpi_win_allocate_shared_' /dat/KERNEL/mpi3_sharedmem.f90:198: undefined reference to `mpi_win_shared_query_' It is just these 2 routines, which are necessary for the MPI3- shared memory access of the same Fortran array from different processes on same node. This is a breakthrough enabled by MPI-3, and for me the most important new feature of MPI-3, because it allows saving much storage in the Ftn-code and reduces a lot of MPI-data transmission required otherwise. Can you tell me, when these 2 important MPI-routines will be available? Thank You Michael Rachner Details: Version of MPI library used in this run: [1,0]<stdout>: Open MPI v1.8.1, package: Open MPI hpcoft14@cl3fr4 Distribution, ident: 1.8.1, Apr 22, 2014 d0000000 cl3fr1 230$mpif90 -show ifort -I/opt/mpi/openmpi/1.8.1-intel-14.0.2/include -I/opt/mpi/openmpi/1.8.1-intel-14.0.2/lib -L/opt/system/torque/4.2.7/lib -Wl,-rpath -Wl,/opt/system/torque/4.2.7/lib -Wl,-rpath -Wl,/opt/system/torque/4.2.7/lib -Wl,-rpath -Wl,/opt/system/torque/4.2.7/lib -Wl,-rpath -Wl,/opt/system/torque/4.2.7/lib -Wl,-rpath -Wl,/opt/mpi/openmpi/1.8.1-intel-14.0.2/lib -Wl,--enable-new-dtags -L/opt/mpi/openmpi/1.8.1-intel-14.0.2/lib -lmpi_usempif08 -lmpi_usempi_ignore_tkr -lmpi_mpifh -lmpi d0000000 cl3fr1 231$ --end of the email ---
