#20 Communicator::receive (this=0x66b150, slice=0x8779e0,
Hello, I'm working on a parallel physical simulation involving particles
in a 3D grid.
In addition to Boost libraries, I use the Eigen3 template library for
holding numerical data in small 3-vectors.
I'm trying to send a 3D boost::multi_array containing std::list of
pointers to particle structs via boost::mpi and keep getting a segfault
on receive.
Sending and receiving boost::multi_array of V3D Eigen3 vectors works fine.
Serialization functions for multi_array are from
http://tinyurl.com/3koafmr (edited for 3 dimensions, seems to work)
Serializing Eigen Vector3d type (seems to work):
friend class boost::serialization::access;
template<class Archive>
inline void serialize(Archive & ar, const unsigned int file_version) {
ar & m_coeffs.x();
ar & m_coeffs.y();
ar & m_coeffs.z();
}
typedef Vector3d V3D; //Convenience typedef for Eigen3 vector
struct Particle {
V3D r, u;
double m, q;
unsigned number;
friend class boost::serialization::access;
template<class Archive>
void serialize(Archive & ar, const unsigned int file_version) {
ar & r; ar & u;
ar & m; ar & q;
ar & number;
}
};
Sending point:
typedef boost::multi_array, 3> ParticleArray;
ParticleArray part_array(boost::extents[x][y][z]);
...fill the array with particles, some cells might be empty...
world->isend(recnum, pack_type, part_array);
Receiving point:
ParticleArray
part_array(boost::extents[slice->shape()[0]][slice->shape()[1]][slice->shape()[2]]);
world->recv(sendnum, pack_type, part_array);
When I get here, it segfaults:

'boost::archive::archive_exception'

Again, this error only shows when receiving the multi_array of
std::list. multi_array of V3D is received fine.
Thanks for any help,
