Thanks, Blair! You've seen C++Next, I suppose?

Reading your book at the moment. Awesome stuff. Bit of a mind bender. Keen to see you publish more material.

Comment on What’s so cool about Boost.MPI? by Rrossi

Well... i use boost mpi and i am very happy with it. Unfortunately i would like to report a bug and i don't know where to. Even the simplest boost mpi program fails when using openmpi >1.2 as it comes with common distributions (at least on ubuntu and redhat).

by googling you can find it is a known issue with openmpi...which will require maintenance on the boos side

the error is:

rrossi@rrossi-notebook:~/Libraries/boost_1_47_0/lib$ python Python 2.7.1+ (r271:86832, Apr 11 2011, 18:13:53) [GCC 4.5.2] on linux2 Type "help", "copyright", "credits" or "license" for more information.

import mpi python: symbol lookup error: /usr/lib/openmpi/lib/openmpi/mca_paffinity_linux.so: undefined symbol: mca_base_param_reg_int

please feel free to contact me for details, i will also try to write you an email about this rrossi@cimne.upc.edu

MPI_AInt offsets[2]; //… for (int i = 3; i != 0; –i) offsets[i] -= offsets[0];

Isn’t this a buffer overrun …

Having started trying using Boost.MPI over the past couple of days, it would be totally great if some sort of Best Practice article was posted somewhere. I have been especially struggling with broadcasting polymorphic objects.
