Try seeing if your memory is actually being used using something like<div><meta http-equiv="content-type" content="text/html; charset=utf-8">vmstat -a -S M 5 5</div><div>ignore the first line and </div><div>check for active memory, which is more meaningful in this case for virtual memory kernels. If it is too big, you'll start swapping, if you run out of swap you'll see that kind of errors. </div>

<b><span style="font-weight:bold">Subject:</span></b> pp.x and dos.x crashes with "memory allocation"<br>
</font></div><div><div></div><div class="h5"><br>
Dear All,<br>I have a problem and I really really appreciate if anybody could help me.<br>I downloaded QE in two machines:<br>intel (R) pentium (R) 4 cpu 3 GHz with total memory 2GB, and<br>intel (R) core (TM) i7 cpu 870 @2.93 GHz, with 4GB total memory.<br>
everything is working perfectly well with the first machine (with
espresso-4.1.2), but dos.x and pp.x both crash with "out of memory/
memory allocation" error in the second machine for big structures
(espresso-4.2.1 and espresso-4.2). It should be noted that pw.x works properly and the "memory allocation" error happens just for dos and post processing.<br>
I downloaded ATLAS and modified "make.sys" accordingly but it didn't
help. I used "ulimit -s unlimited" command, it didn't help either.<br>I have been sending emails for months to all the QE email address, but nobody sent a reply yet, although I subscribed for the forum.<br>
I would be thankful if anyone of you could help me in this regard.<br>
Thanks a lot.<br><font color="#888888">Pari Shok,<br>PhD candidate <br>UMD <br></font>
