Dear Paolo
     Thank you very much for your advice . I still have some questions that need your help .
     I don't know why only display 8 CPUs while I use 2 nodes (16 CPUs) ? Untill now the job only has 2 iterations form 2:00 PM today  ,it is so slowly .
     How can I solve this problem ? 
Best regards
