PROFILE_PRELIB needs to be added *before* libmpifort. Some time after 3.1, we re-organized which symbols go into which libraries and now libmpifort.so contains PMPI_Init and all its weak aliases (MPI_Init, mpi_init_, etc.) This means the MPI_Init symbol is resolved before your library is searched. Can you manually try a compile line with -lfoo before -lmpifort and confirm that it works as expected? I.e. gfortran fpi.f -I/homes/fisaila/software/mpich/include -I/homes/fisaila/software/mpich/include -L/homes/fisaila/software/mpich/lib -lfoo -lmpifort -Wl,-rpath -Wl,/homes/fisaila/software/mpich/lib -Wl,--enable-new-dtags -lmpi Ken _______________________________________________ discuss mailing list discuss(a)mpich.org To manage subscription options or unsubscribe: https://lists.mpich.org/mailman/listinfo/discuss

Thanks Jan, this works indeed for me with mpich-3.1 (by using mpif77 compiler, I think this is what you meant). However, it does not work with mpich-3.1.3.

Re: [mpich-discuss] Assertion failed in file src/mpid/ch3/src/ch3u_handle_send_req.c at line 61 (RMA && Derived datatypes)

Hi Victor, I looked your test code and I think it is due to a bug in our MPICH RMA that the request handler is not re-entrant safe, which makes win_ptr->at_completion_counter being decremented twice for one GET operation. We will fix it as soon as possible. I created a ticket for this: https://trac.mpich.org/projects/mpich/ticket/2204, you can track the progress of this bug on it.

Junchao, as Rajeev mentions, I would like to write the MPI_Init and call PMPI_Init, as I want all MPI codes to work with that.

Florin, As we discussed, it looks your aim is to provide MPI profiling (implemented in C) to Fortran+MPI code. Try this: Implement your profiling layer in PMPI_Xxxx(), and call MPI_Xxxx() in it.

Re: [mpich-discuss] f77 bindings and profiling

Hi, it works what Rajeev suggests, defining the C function as mpi_init_ (one underscore for g77). In this case I would need a wrapper for and one for Fortran. However I understand from Section 14.2.1 of the MPI3 document (thanks Junchao for pointing to this) that I should be able to define just an MPI_Init wrapper in C and the call of MPI_Init(0, 0) from the Fortran implementation of mpi_init should be also redirected to my function. Pavan, I use MPICH-3.1.3. There is slight difference when I run the example you gave me, the libpmpi library does not appear: fisaila@howard:f77$ mpif77 -show fpi.f gfortran fpi.f -I/homes/fisaila/software/mpich/include -I/homes/fisaila/software/mpich/include -L/homes/fisaila/software/mpich/lib -lmpifort -Wl,-rpath -Wl,/homes/fisaila/software/mpich/lib -Wl,--enable-new-dtags -lmpi fisaila@howard:f77$ export PROFILE_PRELIB="-lfoo" fisaila@howard:f77$ mpif77 -show fpi.f gfortran fpi.f -I/homes/fisaila/software/mpich/include -I/homes/fisaila/software/mpich/include -L/homes/fisaila/software/mpich/lib -lmpifort -lfoo -Wl,-rpath -Wl,/homes/fisaila/software/mpich/lib -Wl,--enable-new-dtags -lmpi The mpi and mpifort have the following symbols: fisaila@howard:f77_program$ nm /homes/fisaila/software/mpich/lib/libmpi.a | grep MPI_Init 000000000000146d W MPI_Init 000000000000146d T PMPI_Init fisaila@howard:f77_program$ nm /homes/fisaila/software/mpich/lib/libmpifort.a | grep -i MPI_Init 0000000000000000 W MPI_INIT 0000000000000000 W PMPI_INIT U PMPI_Init 0000000000000000 W mpi_init 0000000000000000 W mpi_init_ 0000000000000000 W mpi_init__ 0000000000000000 W pmpi_init 0000000000000000 T pmpi_init_ 0000000000000000 W pmpi_init__ Thanks Florin ________________________________________ From: Rajeev Thakur [thakur(a)mcs.anl.gov] Sent: Monday, November 17, 2014 3:39 PM To: discuss(a)mpich.org Cc: mpich-discuss(a)mcs.anl.gov Subject: Re: [mpich-discuss] f77 bindings and profiling You need to add the right number of underscores at the end of the C function depending on the Fortran compiler you are using. For gfortran I think it is two underscores. So define the C function as mpi_init__. If that doesn't work, use one underscore. MPICH detects all this automatically at configure time.
