<div dir="ltr">thanks for the kind reply, so I just recently downloaded quantum espresso, and this problem persist when I just run pw.x without specifying any input files, it also of course fails with the example files as well under the PW directory. Do you think it has to do with the version of QE I am running which is 6.3? <div><br></div><div>Sincerely Aziz Fall</div></div><div class="gmail_extra"><br><div class="gmail_quote">On Wed, Aug 8, 2018 at 1:46 PM, Natalie Holzwarth <span dir="ltr"><<a href="mailto:natalie@wfu.edu" target="_blank">natalie@wfu.edu</a>></span> wrote:<br><blockquote class="gmail_quote" style="margin:0 0 0 .8ex;border-left:1px #ccc solid;padding-left:1ex"><div dir="ltr">As I mentioned in a previous entry, we have been experiencing the same very intermittent error for both pw.x and ph.x . We have no ideas about the origin except that it seems to be related to the version of the openmpi library. For 3.1.1-intel-2018 and 3.1.0-intel-2018 the error is rather frequent. For 2.1.0-intel-2018, it seems to happen less frequently. It appears for QE 6.2.1 and 6.3. Unfortunately, it does not appear for very short jobs, but I will be happy to provide a sample input file for an intermediate size job if that will be helpful.....
