Hi Roy I am trying to implement this one: comm().allgather(vector<MyClass>).
The compiler fails. It says MyClass is not a StandardType. I tried with a tuple<>, without success. Any suggestion? Should I specialize a Packing<MyClass *> or so? I can see that for vector<string>, everything works fine. /usr/local/include/libmesh/parallel.h: In instantiation of ‘class libMesh::Parallel::StandardType<abada_lib::MyClass>’: /usr/local/include/libmesh/parallel_implementation.h:3251:23: required from ‘void libMesh::Parallel::Communicator::allgather(std::__debug::vector<_RealType>&, bool) const [with T = abada_lib::MyClass]’ src/abada_lib/Abada_sc10.cxx:323:32: required from here /usr/local/include/libmesh/parallel.h:387:3: error: static assertion failed: Only specializations of StandardType may be used, did you forget to include a header file (e.g. parallel_algebra.h)? static_assert(dependent_false<T>::value, Renato On Fri, Jun 29, 2018 at 9:54 AM, Renato Poli <rebp...@gmail.com> wrote: > Thank you! > > On Thu, Jun 28, 2018 at 6:04 PM, Roy Stogner <royst...@ices.utexas.edu> > wrote: > >> >> On Thu, 28 Jun 2018, Renato Poli wrote: >> >> How can I do this (I am not a MPI guy at all, so please be patient ...): >>> >> >> > ... after each processor makes its own local vector, just >>> > allgather those into a giant serial vector ... >>> >> >> I'm not a big fan of MPI myself, which is why we've got it wrapped up >> as much as possible. >> >> https://github.com/libMesh/libmesh/blob/716878d0c5631a7b7488 >> c88fd1de78025231b115/include/parallel/communicator.h#L664 >> >> is the comment (with API below) for what I described above. >> --- >> Roy >> > > ------------------------------------------------------------------------------ Check out the vibrant tech community on one of the world's most engaging tech sites, Slashdot.org! http://sdm.link/slashdot _______________________________________________ Libmesh-users mailing list Libmesh-users@lists.sourceforge.net https://lists.sourceforge.net/lists/listinfo/libmesh-users
