Hi, I am using Quantum-Espresso 3.1.1. I have installed the program with "make all", but when I run the example02, the example will freeze whenever ph.x is being called. This problem will not exist when I run example01 and example03. I have checked the processor status using "ps" and "top", and I found that there is no problem when running the "pw.x", but when running the "ph.x", the CPU is always 100% full-load but never finish running ph.x. I had to manually kill ph.x anyway. There is no warning message appearing on the screen or in the output files of example02. What is the problem with the ph.x?
******************** here is the result seen on the screen *************** /home/s800000/espresso-3.1.1/examples/example02 : starting This example shows how to use pw.x and ph.x to calculate phonon frequencies at Gamma and X for Si and C in the diamond structure and for fcc-Ni. executables directory: /home/s800000/espresso-3.1.1/bin pseudo directory: /home/s800000/espresso-3.1.1/pseudo temporary directory: /home/s800000/tmp checking that needed directories and files exist... done running pw.x as: /home/s800000/espresso-3.1.1/bin/pw.x running ph.x as: /home/s800000/espresso-3.1.1/bin/ph.x cleaning /home/s800000/tmp... done running the scf calculation... done running the phonon calculation at Gamma... *************************************** That is where the example02 freeze and will not continue no matter how long I wait. Thank you very much for your help! Ivan
