[CPMD-list] How make the calculation as effcient as passible on linux-cluster

[Yuanliang Xie]

Dear Axel,
    Could you please give me some hints on running CPMD on a
with-pgi-opterons-Myrinet-mpi-linux-cluster? Every-node has 4 cpus and
8G memory. 
   I want to make the calculations as effcient as possible . I find only
two keywords about this in the manual :TASKGROUPS and  REAL SPACE WFN
KEEP.  Thanks.
