[Coin-bcpdiscuss] Using BCP in parallel/distributed environment

[Laszlo Ladanyi]

Hi Ali,

Sorry, no other manual exist :-(.

The good news is that BCP does run in a parallel environment using MPI :-).

Since you say "except possibly defining -DCOIN_HAS_MPI in the makefile", I
suspect you are using a very old version you got from cvs. I strongly suggest
to download the latest stable version from svn. Then all you have to do is to
specify the location of the MPI headers and library to the configure script.
When to check out the Bcp package just run the following command:
  <path_to_packae_source>/configure --help=recursive
and that will tell you how to specify the MPI stuff. 

Let me know if you have problems.
