Dear all,

I got a server computer equipped with two 8 core cpus. I installed intel 
fortran compiler (12.1) and openmpi (1.6.5). No errors took place during 
installation. Then I compiled parallel quantum esspresso (5.2.0) and the 
program run correctly. However, I found pw.x  runs at very similar speed with 8 
cores or 16 cores. Could any expert show me how to improve the calculation 
speed?

The make.sys file is attached.

Thanks in advance.
