1) are you sure that  you compiled a parallel CHARMM:
PARALLEL/PARAFULL/MPI/CMPI keywords in the pref.dat file?

2) what gives the following command?
mpirun -np 2 charmm < basic.inp

with basic.inp:
* 
set n ?numnode
stop

You should have something like:
 CHARMM>    set n ?numnode
 RDCMND substituted energy or value "?NUMNODE" to "2"
 Parameter: N <- "2"

3) the latest lam-mpi is 6.5.2, you might consider upgrading ;)

Best regards,

Tru
