<br>
I updated driver and install PV successfully. As you point out,
the recent driver solves the problem. By the way, i installed the
co-processing code with PV with EGL support and now it runs
without any problem and produces desired png files. The only minor
problem is that the result png files do not have axis titles and
axis labels. There could be a bug related with co-processing.<br>
<br>
Thanks for your help and suggestions,<br>

You'll probably want to use PV 5.1.2 or greater for this. Also,
note that the blog post says that the NVIDIA EGL driver minimum
version needed is 355.11.</div>

Andy,<br>
<br>
I am trying to install ParaView with EGL under Centos
7.1 but ParaView configuration could not find following
libraries,<br>
<br>
EGL_gldispatch_LIBRARY <wbr>
EGL_gldispatch_LIBRARY-<wbr>NOTFOUND <wbr>
<br>
EGL_opengl_LIBRARY
EGL_opengl_LIBRARY-NOTFOUND<br>
<br>
I checked the OS and Nvidia drivers and i confirmed that
i don't have libGLdispatch library. <br>
<br>
BTW, i am using Nvidia driver version 352.79. It is
little bit old and now it is 367.57. Do you think that
my driver is not capable to install the ParaView with
EGL? If this is the case, i will try to upgrade the
Nvidia library but i just want to be sure.<br>
<br>
Thanks for your help,<br>

<div>Hi Ufuk,<br>

I haven't heard of any issues like this. Do
you get similar behavior on the machine when
running ParaView with a separate, connected
pvserver? <br>
<br>
</div>
If you have an NVIDIA card you may be able to
use their EGL libs for offscreen rendering
(i.e. no x-windows needed). See the blog post

<br>
I am trying to run a parallel code with
co-processing support but when i run the code,
it is hanging without opening x-window and
writing the png files. In this case, i could
not use or interact with any other app with
GUI such as firefox, terminal etc. It seems
that it affects the GNOME. On the other hand,
if i connect to machine remotely via ssh and
kill the MPI process than the machine back to
the normal and i could interact with terminal
and other apps with GUI nornally. The system
has Centos (7.1) operating system along with
ParaView 5.2.0RC3 (BTW, i compiled ParaView
from source). In this case, i am just running
the code with standard mpirun command as
follows,<br>
<br>
mpirun -np 16 ./main.x<br>
<br>
to find the source of the problem, i included
strace command to the mpirun like following<br>
<br>
mpirun -np 16 strace ./main.x<br>
<br>
and it runs without any problem and produces
desired output. So, at this point i am little
bit confused and i just wonder that is there
anybody else had similar issue before. Strace
somehow solves the problem but i don't know
how. It seems that it is related with the
system because same code runs without any
problem under MacOS. I also compiled code with
ParaView 5.1 and it also hangs. The standard
allinputsgridwriter.py is working without any
problem and writes the data to disk. So,
somehow it is related with the system
(probably GNOME) or the ParaView installation.<br>
<br>
Another question is that is there any way to
prevent opening x-window and still getting
advantage of having GPU in this case? The code
only writes the result in png format. So, i
need installation for headless server (without
any screen attached) but i am not sure. I
think that it requires special configuration
options for the ParaView installation. So,
please let me know also about those special
options.<br>
