Just cherry-picked these two commits into master to fix the serialization issue:

commit 0dce8d2c2ab273c488d708fb3e66dbb9c4298a79
Author: Jürgen Hunold <>

commit 7d33e519b3daa01e9bb4a5545d5d084c45875e4f
Author: K. Noel Belcourt <kbelco_at_[hidden]>

MPI tests are clean on master. Graph_parallel is mostly clean, there’s one issue:

clang-darwin.compile.c++ ../bin.v2/libs/graph_parallel/test/distributed_csr_algorithm_test-1.test/clang-darwin-4.2.1/debug/distributed_csr_algorithm_test.o

In file included from ../libs/graph_parallel/test/distributed_csr_algorithm_test.cpp:25:
In file included from ../boost/graph/dijkstra_shortest_paths.hpp:25:
../boost/pending/relaxed_heap.hpp:194:53: error: no viable conversion from returned value of type 'const value_type' (aka 'const boost::optional<unsigned long>') to function return type 'bool'
  bool contains(const value_type& x) const { return groups[get(id, x)]; }
which looks like a dependency on an un-merged change from graph develop. I’ll have to track this down.
