<div class=Section1>
<p class=MsoNormal>On the Wiki, there is a discussion of using multiple cores
per GPU<o:p></o:p></p>
<p class=MsoNormal><a
href="http://www.paraview.org/Wiki/Setting_up_a_ParaView_Server#Sharing_GPUs_Amongst_Processes">http://www.paraview.org/Wiki/Setting_up_a_ParaView_Server#Sharing_GPUs_Amongst_Processes</a><o:p></o:p></p>
<p class=MsoNormal><o:p> </o:p></p>
<p class=MsoNormal>One key phrase “GPUs can be implicitly shared by
pointing multiple processes to the same display on the same host” tells
me that the selection of the display, assumes that an X server is running and you
tell each node to use DISPLAY:0.0 etc etc depending on number of GPUs shared
between CPUs. In fact later in the wiki this is explicitly written.<o:p></o:p></p>
<p class=MsoNormal><o:p> </o:p></p>
<p class=MsoNormal>Question : Supposing you have no Xserver running but you
wish to take advantage of hardware acceleration. Is it possible to create an
offscreen buffer for each pvserver without the X server. We’d like to
share one GPU between 4 cores, but without starting X.<o:p></o:p></p>
<p class=MsoNormal><o:p> </o:p></p>
<p class=MsoNormal>Can either OpenGL or Mesa (but using GPU not software) be
told to do this.<o:p></o:p></p>
