Thanks Ralph.

Was there a reason this functionality wasn't in from the start then?  LA-MPI works under bproc using shared libraries. 

I know Bproc folks like to kill the notion of shared libs but they are a fact of life we can't live without.

Just my $0.02.

Unfortunately, that's all that is available at the moment. Future releases (post 1.1) may get around this problem.

The issue is that the bproc launcher actually does a binary memory image of the process, then replicates that across all the nodes. This is how we were told to implement it originally by the BProc folks. However, that means that shared libraries have problems, for obvious reasons.

We have to reimplement the bproc launcher using a different approach - will take a little time.

Also, remember that you must configure for static operation for  
bproc - use the configuration options "--enable-static --disable- 
shared". Our current bproc launcher *really* dislikes shared  
libraries.... ;-)
