<div>I first tried your program after removing the boost declarations, and it worked correctly:</div>

<div>#include<cstdlib></div>
<div>#include<cstring></div>
<div>#include<iostream></div>
<div>#include<vector></div>
<div>#include<pthread.h></div>
<div>#include<mpi.h></div>
<div><br>
</div>
<div>using namespace std;</div>
<div><br>
</div>
<div>#define MASTER 0</div>
<div><br>
</div>
<div>int main(int argc, char *argv[])</div>
<div>{</div>
<div> int rankID, numprocessors,provided;</div>
<div> int returnvalue = MPI_Init_thread(&argc,&argv,MPI_THREAD_MULTIPLE,&provided);</div>
<div><br>
</div>
<div> printf("\n VALUE OF PROVIDED IS %d",provided);</div>
<div> printf("\n VALUE OF MPI_THREAD_MULTIPLE IS %d",MPI_THREAD_MULTIPLE);</div>
<div> if(provided < MPI_THREAD_MULTIPLE)</div>
<div> {</div>
<div> printf("\n THREAD LIBRARY DOESN'T HAVE MULTITHREADING SUPPORT:");</div>
<div> }</div>
<div><br>
</div>
<div> MPI_Finalize();</div>
<div><br>
</div>
<div> return 0;</div>
<div>}</div>
</div>
<div><br>
</div>
<div>With respect to Boost, yes, MPICH works correctly with Boost. But it is possible that something is not setup correctly in your installation of Boost. Did you make sure you are linking with the correct MPI library?</div>
