<div>Dear users</div>
<div> </div>
<div>I installed pwscf on the RH.Linux with 2G memory(2 CPUs and 4 processes). MPICH1.2.7,Ifort,lapack-3.1.1, BLAS and fftw-3.2 have been successfully installed, too. The subsequent installation process of PWscf report no error. All the example tests are successful. In addition, I selected a surface slab model to make another couples of test. I met some problems: 1. I typed " mpirun -np 4 ~/bin/pw.x <IO.inp |tee IO.out &" , then I followed the content of output file closely, finding it stops after the lines:</div>

<div>but pw.x process is still occupying 4x25 % cpu and 10 % MEM. I wait for hours and there are no further new contents read from the output file. I don't know whether it is the overflow of the memery? Could anybody help me with these problems? Thanks.</div>

<div>Attached file is the make.sys of the PWscf.</div>
