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

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.
Hi Alessandro,
If I interpret your question correctly it looks
like you did not use mpirun to start your parallel
apbs job, which is what you need to do.
Have a look at mpirun's man page which should
get you started.
Best,
Markus
