[gentoo-science] MPI and multicore + lib question

[Alessandro Yoshi Polliotti <polliotti@bo.imm.cnr.it>]

I hope I'm not asking anything too obvious but I wasn't able to find relevant 
information online.

I have installed apbs enabling mpi, it works but it detects only one cpu in my 
core duo system. Strictly speaking it's correct, but not quite what I 
expected. I would like to know more about this behaviour, is it due to my 
misconfiguration of apbs, mpi, kernel or other factors?

Besides this, trying to make apbs detect my two cores I tried also mpich2 and 
lam-mpi as mpi implementations. Using both of them and recompiling maloc apbs 
will complain that maloc has not been compiled with mpi support, and will 
keep mpi out of the build process. maloc however doesn't print any warning.

Thanks in advance
