Dr. R.K.thapa If the installer of intel compilers does not work properly, the OS of your PC might not recognize your hardware.
You should have got some message from the installer. Check your system monitor and confirm that the name and number of your processors are correct. You should look at the FAQ or forum of intel compilers. I attached the mail that I installed the system. p.s. I have my PC installed on CentOS 6.0 which figured out my hardware successfully.
