<div class="moz-cite-prefix">Hi 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
EGL_gldispatch_LIBRARY-NOTFOUND
<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>
Regards,<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>

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

<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>
<br>
