Dear All,

  I am using Dell Precision T5600 Server with 32 gb Ram and
 Processor:  intel xeon E5-2620 @2.00GHZ * 18
 Operating System: Ubuntu12.04 and showing cpu 1 to cpu 24 in resources
section of system information

 when i tried to run the wrf.exe using mpirun (mpirun -np 12 ./wrf.exe) for
1 month period over a particular place for 50 tiles with a resolution of
5.6Km, the time taking to complete the run is almost 5 hrs.

and i have one more assembled system with same Operating System and 4GB Ram,
 processor: intel core i3-3210 at 3.00GHz * 4

I tried to run the same process for same period using mpirun -np 4
./wrf.exe , the time taken to complete the process is almost 5 hours.

Both the systems are working at the same speed.

i am confusing about this?. How can i increase my T5600 Server performance.
Please give me any idea to solve the issue

Awaiting for your reply

Thanks,

Regards,
