Dear all,<div><br><div>I've been doing electron-phonon-coupling calculation on a Hexagonal system using the newly incorparated Grid parallelization method in QE5.0.1, the total q points in irr BZ in my case are 7, so naturally I split the el-ph calculation into 7 individual job using the <<start_q, last_q>> flags and submit to the cluster simultaneously.</div>
</div><div><br></div><div>Everything goes well except when it comes to the restart part(have to restart due to the limited wall time on cluster). The problem is when the job restarted successfully from previous run for q # 2 to # 7, the q#1 part has to be calculated in these q(in my first run, the job for q#1 hasn't finished), i.e., for these q(2-7), the job seems can't continue to run separately as I expected.</div>
<div><br></div><div>Here is part of output for q#2 from restart run.</div><div>__________________________________________________________________________</div><div>__________________________________________________________________________</div>

<div><br></div><div>I wonder if this is a bug or actually the code intend to behave like this, any ideas will be greatly approciated, thanks in advanve.</div><div><br></div><div>all the best</div><div><br></div><div>Xiao-long Zhang</div>
