<p>Please include your affiliation when posting to the forum.</p>
<p>In my experience with QE-GPU v5.3.0 and v5.4.0, the working
combination of software is,</p>
<p>1) Intel PSXE 2017</p>
<p>2) CUDA 6.5 or 7.0</p>
3) Centos 7.1<br>
<br>
Please try the above combination.<br>

Currently I am using two Tesla K40m cards for my computational
work on quantum espresso (QE). My GPU enabled QE code running
very slower than normal version. My question was weather
particular application will be fast only in some versions of
CUDA toolkit? (as mentioned in previous post: <a
href="http://qe-forge.org/pipermail/pw_forum/2015-May/106889.html"
moz-do-not-send="true">http://qe-forge.org/pipermail/pw_forum/2015-May/106889.html</a>)
OR is there any other reason hindering performance (memory) of
GPU? (when I am hitting top command in my server, option of
'VIRT' showing different values (top command pasted in
attached file))<br>
<br>
Some error was generating while submitting code that "A
high-performance Open MPI point-to-point messaging module was
unable to find any relevant network interfaces: Module:
OpenFabrics (openib) Host: XXXX Another transport will be
used instead, although this may result in lower performance".
Is this MPI thread hindering GPU performance ?</div>

(P.S: We don't have any Infiband adapter HCA in server)<br>
<br>
<br>
Current details of server are (full details attached):<br>
<br>
Server: FUJITSU PRIMERGY RX2540 M2<br>
CUDA version: 9.0<br>
NVIDIA driver: 384.9<br>
openmpi version: 2.0.4 with intel mkl libraries <br>
QE-gpu version : 5.4.0<br>

<br>
Thanks in advance<br>
