Dear Stefano,<br><br>Thanks for your answer.<br><br>I'm not absolutely sure what it is. I did some tests that led me to this conclusion. <br><br>Initially I have started the NEB method without using the image parallelization level and the PWscf seems to be running correctly. Below the command line I'm using:<br>
<br>mpirun -n $NSLOTS /home/u/almartin/intel/espresso-4.1.2/bin/pw.x < /home/u/almartin/cosb3/neb/<a href="http://cosb3_neb.in">cosb3_neb.in</a><br><br>But when I run with two images I got the following error:<br><br>
forrtl: severe (67): input statement requires too much data, unit 16, file /dados/almartin/neb/neb.igk6 <br><br>The command line I'm using is:<br><br>mpirun -n $NSLOTS /home/u/almartin/intel/espresso-4.1.2/bin/pw.x -nimage 2 < /home/u/almartin/cosb3/neb/<a href="http://cosb3_neb.in">cosb3_neb.in</a><br>
<br>The "/dados/almartin/neb/" is a shared file system directory. I'm using an infrastructure in which I can not use a local directory as output or temporary directory.<br><br>I did some searching the Web and found that this error occurs due to overwritten files.<br>

Dear Andre Martinotto<br>
I don't think this should be the case....why do you think it could be<br>
that ?<br>
Even if this were happening (which I think shouldn't) the .igk file<br>
of each image should be the same so your problem is something else. Are<br>
you sure you are not running two instances of the same job concurrently<br>
? or two different jobs using the same outdir ... ?<br>
