[mpich-discuss] mpic++/mpicxx?

[Jayesh Krishna]

Hi,
 Follow the steps below to build Boost with MPICH2.

Assumptions
--------------
# MPICH2 is already installed in your system
# Visual Studio Compiler is installed in your system

Step 1
---------
 Add the lines below to your "tools/build/v2/user-config.jam" (You can also refer to http://www.boost.org/doc/libs/1_47_0/doc/html/mpi/getting_started.html for details). Add the lines to the end of the file.

----------------------- userconfig.jam ---------------------------
...

# MPI Configuration
import path ;
local mpich2_path_win = "C:\\Program Files\\MPICH2" ;
local mpich2_path = [ path.make $(mpich2_path_win) ] ;
using mpi : :   <include>$(mpich2_path)/include
                <address-model>64
                <library-path>$(mpich2_path)/lib
                <find-static-library>cxx
                <find-static-library>mpi
            ;
.mpirun = "\"$(mpich2_path)\\bin\\mpiexec.exe"\" ;
.mpirun_flags = -n ;

----------------------- userconfig.jam ---------------------------

Step 2
---------
 Use bjam to make and install the MPI library. Make sure that you use a command similar to the one below to specify the type of the build (Since MPICH2 libs are MultiThreaded Static libraries you need to make sure that you build MT static boost libs too, as below).

C:\boost_1_47_0>bjam --prefix=c:\boost_1_47_0_install link=static threading=multi runtime-link=static --with-mpi install

Step 3
----------
 Try a Boost MPI hello world program (http://www.boost.org/doc/libs/1_39_0/doc/html/mpi/tutorial.html).

 Hope this helps.

Regards,
Jayesh

Hi Jayesh, would you? I'd really appreciate that! I just updated to 
boost 1.47 (the latest). What exactly is the compiler wrapper/batch file 
meant to accomplish anyway? Would using a version of mpic++/mpicxx 
provided by a different MPICH2 implementation work equally well or is it 
very implementation dependent?

Thank you!

Hi,
  Unfortunately I currently don't have the jam files or the batch file 
that you need. Which version of boost are you using ? I can try 
modifying the jam files for the same and provide you (in a couple of days).

Hi Jayesh and thanks for your response, do you have a working copy of
said batch file and a list of changes that you made to the installer
(installed files?) and jam files that I could use? I'd really appreciate
any help I could get so that I can get up, running and back to coding asap.

Unrelatedly is this list available via gmane? If not, can it be? It'd
make browsing it infinitely easier.

Thank you!
