Hi,dear all!
   I want to use BO-PIMD for calculations, but I find that the job will dead aft
er reading RESTART files, and when I specify the parameter PROCESSOR GROUPS,and 
let it equal 1, the job works,and the only way to make it work.But the efficienc
y is not high.Why can't I use more than one processor groups? the input file is 
as below.
