Hi Clara,<br>
<br>
Even for a single node, Hydra is still the preferred process manager. For most platforms, you might be able to discard -lopa.<br>
<br>
Another trick you can do is to configure mpich2 with --enable-lib-depend and --enable-shared. This will still create multiple libraries, but libmpich.so will depend on libmpl.so and libopa.so, so these libraries will automatically get loaded when linked against libmpich.so. This trick is still experimental, and if things break you are on your own :-).<br>
<br>
Hope that helps.<br><font color="#888888">

I am doing some research about MPI implementation on a single node, so I<br>
wish I can get a mpich2 with necessary libraries as little as possible.<br>

Are -lopa -lmpl necessory for building programs with mpich2 using<br>
gforker process manager? Thanks.<br>
<br>
<br>
Yes, they are needed. Also, is there a reason for you to use gforker<br>
and not the default Hydra process manager?<br>
