Boost
There are currently three different versions of Boost C++ Libraries installed on all the PMACS cluster nodes.
Boost v1.41.0 is the system default version and can be linked to programs without any additional work.
Note : The default version of Boost may not include all the desired libraries. For example MPI library bindings may not work as expected.
Additional versions of Boost
Boost v1.55.0 and v1.57.0 are both available as modules. The example C++ code below can be used to test Boost v1.55.0 and v1.57.0 functionality on the PMACS cluster but not the system default version.
#include <iostream>
// The boost headers
#include "boost/mpi.hpp"
int main(int argc, char* argv[])
{
// Allows you to query the MPI environment
boost::mpi::environment env( argc, argv );
std::string processor_name( env.processor_name() );
// permits communication and synchronization among a set of processes
boost::mpi::communicator world;
unsigned int rank( world.rank() ), numprocessors( world.size() );
if ( rank == 0 ) {
std::cout << "Processor name: " << processor_name << "\n";
std::cout << "Master (" << rank << "/" << numprocessors << ")\n";
} else {
std::cout << "Slave (" << rank << "/" << numprocessors << ")\n";
}
return 0;
}
Copy the code above into a file called boost_test.cpp
Boost v1.55.0
The above code snippet is intended to verify Boost.MPI library functionality. Follow the steps below in an interactive node:
Load the appropriate Boost version module:
[asrini@consign ~]$ bsub -Is bash [asrini@node062 ~]$ ls boost_test.cpp boost_test.cpp [asrini@node062 ~]$ module load openmpi-1.5.4-x86_64 [asrini@node062 ~]$ module load boost-1.55.0
Now compile the code against the version of Boost you are testing.
[asrini@node062 ~]$ mpic++ -W -Wall -L/opt/software/boost/1.55.0/lib/ -lboost_mpi -lboost_serialization -lboost_system -lboost_filesystem -lboost_graph_parallel -lboost_iostreams boost_test.cpp -o Boost
Verify that the executable created was indeed compiled against this version of Boost:
