https://svn.boost.org/trac10/ticket/2485 <p> The broadcast function is crashing and I can't see anything that I am doing wrong. Below I have the code and output to a very simple program that I used test the boost API. </p> <p> I compiled the boost libraries using Visual Studio 2008 SP1. I linked the MPI library against msmpi that is provided with the HPC server 2008 SDK. I ran this on a single HPC server 2008 box, so there is no cluster involved. It is the simplest case possible. </p> <p> Thanks for your help, Bryon </p> <p> Example Program <strong></strong><strong></strong><strong></strong><strong></strong><strong></strong><strong></strong><strong></strong><strong></strong><strong></strong><strong></strong><strong></strong><strong></strong><strong>* int main(int argc, char* argv[]) { </strong></p> <blockquote> <p> mpi::environment env(argc, argv); mpi::communicator world; char value<a class="changeset" href="https://svn.boost.org/trac10/changeset/128" title="*** empty log message *** ">[128]</a>={'\0'}; if(world.rank()==0){ </p> <blockquote> <p> strcpy(value,"Hello Bryon from C API\0"); cout&lt;&lt;"start "&lt;&lt;value&lt;&lt;endl; </p> </blockquote> <p> } </p> </blockquote> <p> </p> <blockquote> <p> MPI_Bcast(value,12 , MPI_INT, 0, MPI_COMM_WORLD); std::cout&lt;&lt;world.rank()&lt;&lt;" " &lt;&lt; value&lt;&lt;std::endl; </p> </blockquote> <blockquote> <p> bool was_successful=false; if(world.rank()==0) </p> <blockquote> <p> was_successful=true; </p> </blockquote> <p> mpi::broadcast(world,was_successful,0); std::cout&lt;&lt;world.rank()&lt;&lt;" :"&lt;&lt;(was_successful?"Success with broacasting boolean":"Failure with broadcasting boolean")&lt;&lt;std::endl; </p> </blockquote> <blockquote> <p> std::string bvalue; if(world.rank()==0) </p> <blockquote> <p> bvalue="Hello Bryon from boost API with string."; </p> </blockquote> <p> mpi::broadcast(world,bvalue,0); std::cout&lt;&lt;world.rank()&lt;&lt;" :"&lt;&lt;bvalue&lt;&lt;std::endl; </p> </blockquote> <blockquote> <p> return 0; </p> </blockquote> <p> } </p> <p> Output <strong></strong><strong></strong><strong></strong><strong></strong><strong></strong><strong></strong><strong></strong><strong></strong><strong></strong><strong></strong><strong></strong><strong></strong><strong></strong><strong></strong> </p> <p> E:\HPC Class\hpcs-day3\HPCS-Day3\demos\09 MPI-Send-Recv\TaskParallelMPI\x64\rele ase&gt;mpiexec -n 2 TaskParallelMPI start Hello Bryon from C API 0 Hello Bryon from C API 0 :Success with broacasting boolean 1 Hello Bryon from C API 1 :Success with broacasting boolean </p> <p> This application has requested the Runtime to terminate it in an unusual way.
