<p>Dear Q.E community,</p>
<p>I have been attempting to parallelize an electron-phonon calculations using irreducible representations as described in</p>
<p><a href="http://users.ictp.it/~pub_off/lectures/lns024/10-giannozzi/10-giannozzi.pdf">http://users.ictp.it/~pub_off/lectures/lns024/10-giannozzi/10-giannozzi.pdf</a></p>
<p>However, my grid setup step with start_irr=0 and last_irr=0 produces no output and appears to stop early.</p>
<p>Input file:</p>
<p> </p>
<p>&INPUTPH<br />outdir='.',<br />trans=.true.,<br />ldisp=.true.,<br />nq1=1,<br />nq2=1,<br />nq3=1,<br />start_irr=0,<br />last_irr=0,<br />fildvscf='elph_vscf',<br />electron_phonon='interpolated',<br />/</p>
<p>Output file:</p>
<p>Normal up to printing of the q-points to be calculated, but then just stops abruptly before printing anything about the representations to be done. The last few lines look like:</p>
<p>Dynamical matrices for ( 1, 1, 1) uniform grid of q-points<br /> ( 1 q-points):<br /> N xq(1) xq(2) xq(3) <br /> 1 0.000000000 0.000000000 0.000000000</p>
<p>Weirdly, I had it working for the same system not too long ago, but it is no longer producing the necessary files in _ph0/pwscf.phsave/ directory. I've tried a few compilers/versions of q-e (including the developer version)/combinations of input parameters with the same results.</p>
<p>Have I made a stupid mistake / has anyone had these problems before?</p>
<p>Thanks for your time,</p>
<p>Michael</p>
