[random] Missing Advapi32.lib
by Juan Carlos Franzoy 15 Oct '13

15 Oct '13

Hello. I am relatively new to boost. I am trying to compile boost-1.52 in a windows server 2008R2 using visual studio 2012 express. I got an error linking random dll: random_device.obj : error LNK2019: unresolved external symbol __imp__CryptAcquireContextA@20 referenced in function "public: __thiscall boost::random::random_device::impl::impl(class std::basic_string<char,struct std::char_traits<char>,class std::allocator<char> > const &)" (??0impl@random_device@random@boost@@QAE@ABV?$basic_string@DU?$char_traits@D@std@@V?$allocator@D@2@@std@@@Z) The same error repeats for 'CryptReleaseContext', 'CryptGenRandom' and 'CryptEnumProvidersA'. The problem does not happend if I add '<toolset>msvc:<linkflags>advapi32.lib' to the requirements in random/build/Jamfile.v2. Anyone has seen this before? -- Juan Carlos Franzoy Licenciado en Sistemas

I need to implement non-blocking communication in my application. I am getting segfault when calling wait() on my irecv requests: Program received signal SIGSEGV, Segmentation fault. 0x00007ffff7903a69 in boost::archive::detail::basic_iarchive_impl::load_preamble (this=0x110b590, ar=..., co=...) at libs/serialization/src/basic_iarchive.cpp:319 (gdb) bt #0 0x00007ffff7903a69 in boost::archive::detail::basic_iarchive_impl::load_preamble (this=0x110b590, ar=..., co=...) at libs/serialization/src/basic_iarchive.cpp:319 #1 0x00007ffff7904c52 in boost::archive::detail::basic_iarchive_impl::load_pointer (this=0x110b590, ar=..., t=@0x7fffffffd348: 0x2, bpis_ptr=0x0, bpis_ptr@entry=0x950a50 <boost::serialization::singleton<boost::archive::detail::pointer_iserializer<boost::mpi::packed_iarchive, std::vector<double, std::allocator<double> > > >::get_instance()::t>, finder=finder@entry=0x44d5c0 <boost::archive::detail::load_pointer_type<boost::mpi::packed_iarchive>::find(boost::serialization::extended_type_info const&)>) at libs/serialization/src/basic_iarchive.cpp:446 #2 0x00007ffff79042e8 in boost::archive::detail::basic_iarchive::load_pointer (this=this@entry=0x110b3b0, t=@0x7fffffffd348: 0x2, bpis_ptr=bpis_ptr@entry=0x950a50 <boost::serialization::singleton<boost::archive::detail::pointer_iserializer<boost::mpi::packed_iarchive, std::vector<double, std::allocator<double> > > >::get_instance()::t>, finder=finder@entry=0x44d5c0 <boost::archive::detail::load_pointer_type<boost::mpi::packed_iarchive>::find(boost::serialization::extended_type_info const&)>) at libs/serialization/src/basic_iarchive.cpp:550 #3 0x0000000000451f72 in boost::archive::detail::load_pointer_type<boost::mpi::packed_iarchive>::invoke<std::vector<double, std::allocator<double> >*> (ar=..., t=@0x7fffffffd348: 0x2) at /usr/include/boost/archive/detail/iserializer.hpp:524 #4 0x00000000004521e8 in load<boost::mpi::packed_iarchive, std::vector<double>*> (t=<optimized out>, ar=...) at /usr/include/boost/archive/detail/iserializer.hpp:592 #5 load_override<std::vector<double>*> (t=<optimized out>, this=0x110b3b0) at /usr/include/boost/archive/detail/common_iarchive.hpp:66 #6 load_override<std::vector<double>*> (version=0, x=<optimized out>, this=0x110b3b0) at /usr/include/boost/mpi/packed_iarchive.hpp:101 #7 load_override<std::vector<double>*> (version=0, x=<optimized out>, this=0x110b3b0) at /usr/include/boost/mpi/packed_iarchive.hpp:118 #8 operator>><std::vector<double>*> (t=<optimized out>, this=0x110b3b0) at /usr/include/boost/archive/detail/interface_iarchive.hpp:60 #9 deserialize (stat=..., this=0x110b390) at /usr/include/boost/mpi/communicator.hpp:1335 #10 boost::mpi::request::handle_serialized_irecv<std::vector<double, std::allocator<double> >*> (self=0x11acf30, action=<optimized out>) at /usr/include/boost/mpi/communicator.hpp:1457 #11 0x00007ffff7b5663f in boost::mpi::request::test (this=this@entry=0x11acf30) at libs/mpi/src/request.cpp:66 #12 0x000000000045052d in boost::mpi::wait_all<__gnu_cxx::__normal_iterator<boost::mpi::request*, std::vector<boost::mpi::request, std::allocator<boost::mpi::request> > > > (first=..., last=...) at /usr/include/boost/mpi/nonblocking.hpp:262 #13 0x000000000044be38 in opice::Communicator::waitall_recv (this=0x9a76c0) at /media/data/prog/workspace/opice/src/communicator.cpp:257 #14 0x0000000000424c14 in opice::Boundary::set_J (this=0xbd2b40) at /media/data/prog/workspace/opice/src/boundary.cpp:423 #15 0x00000000004354a6 in opice::Experiment::run (this=this@entry=0x99d850) at /media/data/prog/workspace/opice/src/experiment.cpp:211 #16 0x0000000000415b02 in main (argc=1, argv=0x7fffffffd708) at /media/data/prog/workspace/opice/src/opice.cpp:41 (gdb) In the program, parallelization is achieved using domain decomposition. There is a Boundary class which calls the communication routines, the boundary has several "BorderComm" objects (two in current version) - each of them communicates with one neighbor. There is one Communicator object which holds the data about MPI communicator, handles MPI initialization, etc. Relevant parts look somewhat like this: class Boundary { public: void set_J(); private: BorderComm *sbx_max, *sbx_min; Communicator* comm_; }; void Boundary::set_J(){ if(sbx_min) sbx_min->receive_J(); if(sbx_max) sbx_max->receive_J(); if(sbx_max) sbx_max->send_J(); if(sbx_min) sbx_min->send_J(); comm_->waitall_recv(); if(sbx_max) sbx_max->save_J(); if(sbx_min) sbx_min->save_J(); comm_->waitall_send(); } class BorderComm { public: void send_J(); void receive_J(); void save_J(); int neighbor_; private: V3Slice *slice_J_border_; std::vector<double> *recv_array_; Communicator* comm_; }; void BorderComm::send_J() { comm_->send_fields(slice_J_border_, TYPE_J, neighbor_); } void BorderComm::receive_J(){ recv_array_ = new std::vector<double>(LEN); comm_->receive_fields(recv_array_, TYPE_J, neighbor_); } void BorderComm::save_J(){ .... put contents of recv_array_ into some V3Slice .... delete(recv_array_); } class Communicator { public: void send_fields(V3Slice* slice, PackType pack_type, int recnum); void receive_fields(std::vector<double>* recv_array, PackType pack_type, int sendnum); void waitall_send(); void waitall_recv(); protected: boost::mpi::communicator *world_; std::vector<boost::mpi::request> send_requests_; std::vector<boost::mpi::request> recv_requests_; }; void Communicator::send_fields(V3Slice* slice, PackType pack_type, int recnum) { std::vector<double> send_array(LEN); ..... fill send_array from V3Slice object ..... send_requests_.push_back(world_->isend(recnum, pack_type, send_array)); } void Communicator::receive_fields(std::vector<double>* recv_array, PackType pack_type, int sendnum) { recv_requests_.push_back(world_->irecv(sendnum, pack_type, recv_array)); } void Communicator::waitall_send(){ boost::mpi::wait_all(send_requests_.begin(), send_requests_.end()); send_requests_.clear(); } void Communicator::waitall_recv(){ boost::mpi::wait_all(recv_requests_.begin(), recv_requests_.end()); recv_requests_.clear(); } Now if I move to frame #13 in the backtrace - to get inside the Communicator class, and look at the requests, I get: (gdb) frame 13 #13 0x000000000044be38 in opice::Communicator::waitall_recv (this=0x9a76c0) at /media/data/prog/workspace/opice/src/communicator.cpp:257 (gdb) print recv_requests_ $1 = std::vector of length 2, capacity 2 = {{m_requests = {0x94f0c0 <ompi_request_null>, 0x94f0c0 <ompi_request_null>}, m_handler = 0x452040 <boost::mpi::request::handle_serialized_irecv<std::vector<double, std::allocator<double> >*>(boost::mpi::request*, boost::mpi::request::request_action)>, m_data = {px = 0x110b390, pn = {pi_ = 0x1103940}}}, {m_requests = {0xa40380, 0x94f0c0 <ompi_request_null>}, m_handler = 0x452040 <boost::mpi::request::handle_serialized_irecv<std::vector<double, std::allocator<double> >*>(boost::mpi::request*, boost::mpi::request::request_action)>, m_data = {px = 0x11ab900, pn = {pi_ = 0x11a3ec0}}}} (gdb) print send_requests_ $2 = std::vector of length 4, capacity 4 = {{m_requests = {0xa3f700, 0xa3f400}, m_handler = 0x0, m_data = {px = 0x11074c0, pn = {pi_ = 0x1105ff0}}}, {m_requests = {0xa3f100, 0xa3ee00}, m_handler = 0x0, m_data = {px = 0x11ab640, pn = {pi_ = 0x118efc0}}}, {m_requests = {0x114ec80, 0x114e980}, m_handler = 0x0, m_data = {px = 0x11aceb0, pn = {pi_ = 0x11a3770}}}, {m_requests = {0x114e680, 0x114e380}, m_handler = 0x0, m_data = {px = 0x11ad570, pn = {pi_ = 0x11a1cd0}}}} Until now, I have been using a 1D domain-decomposition algorithm, where each of the domains communicated with its two neighbors using non-blocking sends (preceded by a wait) matched with blocking recvs. Now I need to move to 3D decomposition, where each domain gets 26 neighbors. If I were to use blocking communication, I would have to devise a non-trivial algorithm to avoid deadlocks. Non-blocking communication seems a better option. So - in previous version, there was no need for waitall functions. Instead of: std::vector<boost::mpi::request> send_requests_; std::vector<boost::mpi::request> recv_requests_; there was just a single boost::mpi::request in my Communicator class. There was a call to request.wait() at the beginning of Communicator::send_fields(), and Communicator::receive_fields() used recv() instead of irecv(). This worked, but the order of communication in Boundary::set_J() had to be fixed (send to left, recv from right, send to right, recv form left). Now that would be very ugly for up to 26 neighbors, so the idea was to: 1. isend everything 2. irecv everything 3. wait until everything is received 4. save received data 5. wait until everything is sent 6. exit the function, continue other computation.... All other functions - i.e. creating the recv_array_, copying from my V3Slice object, etc. are the same as in the "blocking version"

[system] Default error codes
by Gavin Lambert 10 Oct '13

10 Oct '13

boost/system/error_code.hpp defines "errc" as a collection of standard error codes (based on posix). It also defines a constructor for error_code and error_condition that allows them to accept a single parameter of an enum type when is_error_code_enum is defined to true for that enum type. It does not, however, actually do this for its own errc enum. As a result, code such as this fails to compile: boost::system::error_code ec(boost::system::errc::operation_canceled); Is there some good reason for this, or is it an oversight? It's certainly more annoying to have to explicitly specify the generic_category().

[iostreams] - Using sparse Windows files
by Byrne, Kevin 10 Oct '13

10 Oct '13

Hello, I am trying to write cross-platform Boost code that utilizes sparse files on Windows7 and FreeBSD. I already have Windows code that creates and accesses a sparse file. I am of the understanding that Boost code cannot create a Windows7 sparse file for me so I am trying to create the file using the Windows code and then replace my ReadFileEx() and WriteFileEx() with Boost streams. I have had luck with using iostreams::file to access an existing Windows sparse file but it fails when I have to read a sparse area thinking it is at the end of the file. I tried creating a stream using an existing HANDLE but was not successful in reading or writing file content. Before I proceed further I thought I would ask first if Boost is capable of using Windows7 sparse file technology. If it is capable I would appreciate some guidance on how. I have done a bit of searching on the web with not much helpful information. Regards, Kevin

[type_traits] ice_or / ice_and not documented but recommended in coding guidelines
by Adam Romanek 10 Oct '13

10 Oct '13

Hi, I have a concern about the usage of boost::type_traits::ice_or and boost::type_traits::ice_and. I've seen it used in many places and it's even recommented in Coding Guidelines for Integral Constant Expressions [1]. The question is: why isn't it documented? Is there any reason for it? Is there any "public" (documented) equivalent? WBR, Adam Romanek [1] - http://www.boost.org/development/int_const_guidelines.html
