<div dir="ltr"><div><div>Dear Pwscf,<br><br></div> Recently i did some calculations in HPC and some in workstation. when i did HPC i did not get imaginary frequencies in my phonon band. When i did it in work station i got negative frequencies. So, i just want to know that the Quantum Espresso is completely dependent on system parameters.<br>
<br></div>Thank you in advance...<br clear="all"><div><div><div><br></div></div></div></div>
