<div dir="ltr"><div><div>Hi all,<br><br></div>I'd like to use MPI pvserver to take advantage of some 48 core nodes we have on our cluster. There's not much in the way of GPUs, so I've been trying to take the route of using OSMesa with --use-offscreen-rendering. The pvserver seems to start well, but as soon as a client connects, the thing aborts. In particular, if I try to use pvbatch with a basic sphere rendering, the pvserver crashes on running the Render(view) part of the script. Pasted below is the error.<br><br></div><div>Does anyone have any insight on this?<br><br><blockquote class="gmail_quote" style="margin:0px 0px 0px 0.8ex;border-left:1px solid rgb(204,204,204);padding-left:1ex">Waiting for client...<br>Connection URL: cs://node0:11111<br>Accepting connection(s): node0:11111<br>[node0:55287] 47 more processes have sent help message help-mpi-btl-base.txt / btl:no-nics<br>[node0:55287] Set MCA parameter "orte_base_help_aggregate" to 0 to see all help / error messages<br>d^LClient connected.<br>[node0:55292] *** Process received signal ***<br>[node0:55292] Signal: Aborted (6)<br>[node0:55292] Signal code:  (-6)<br>[node0:55292] [ 0] /lib64/libpthread.so.0(+0x12420)[0x7fbf80742420]<br>[node0:55292] [ 1] /lib64/libc.so.6(gsignal+0xcb)[0x7fbf7e2f69fb]<br>[node0:55292] [ 2] /lib64/libc.so.6(abort+0x1b0)[0x7fbf7e2f8800]<br>[node0:55292] [ 3] /opt/OpenFOAM/ThirdParty-5.0/ParaView-5.4.0/build/lib/libvtkRenderingOpenGL2-pv5.4.so.1(_ZN22vtkXOpenGLRenderWindow13CreateAWindowEv+0x4e2)[0x7fbf6adf6964]<br>[node0:55292] [ 4] /opt/OpenFOAM/ThirdParty-5.0/ParaView-5.4.0/build/lib/libvtkRenderingOpenGL2-pv5.4.so.1(_ZN21vtkOpenGLRenderWindow29CreateHardwareOffScreenWindowEii+0xa2)[0x7fbf6ad5aa1c]<br>[node0:55292] [ 5] /opt/OpenFOAM/ThirdParty-5.0/ParaView-5.4.0/build/lib/libvtkRenderingOpenGL2-pv5.4.so.1(_ZN22vtkXOpenGLRenderWindow21CreateOffScreenWindowEii+0x32)[0x7fbf6adf7be6]<br>[node0:55292] [ 6] /opt/OpenFOAM/ThirdParty-5.0/ParaView-5.4.0/build/lib/libvtkRenderingOpenGL2-pv5.4.so.1(_ZN22vtkXOpenGLRenderWindow10InitializeEv+0xaa)[0x7fbf6adf7ffc]<br>[node0:55292] [ 7] /opt/OpenFOAM/ThirdParty-5.0/ParaView-5.4.0/build/lib/libvtkRenderingOpenGL2-pv5.4.so.1(_ZN21vtkOpenGLRenderWindow14SupportsOpenGLEv+0x105)[0x7fbf6ad5beb7]<br>[node0:55292] [ 8] /opt/OpenFOAM/ThirdParty-5.0/ParaView-5.4.0/build/lib/libvtkPVClientServerCoreRendering-pv5.4.so.1(_ZN23vtkPVDisplayInformation21SupportsOpenGLLocallyEv+0xeb)[0x7fbf78223b81]<br>[node0:55292] [ 9] /opt/OpenFOAM/ThirdParty-5.0/ParaView-5.4.0/build/lib/libvtkPVClientServerCoreRendering-pv5.4.so.1(_ZN23vtkPVDisplayInformation14CopyFromObjectEP9vtkObject+0x31)[0x7fbf78223c05]<br>[node0:55292] [10] /opt/OpenFOAM/ThirdParty-5.0/ParaView-5.4.0/build/lib/libvtkPVServerImplementationCore-pv5.4.so.1(_ZN16vtkPVSessionCore25GatherInformationInternalEP16vtkPVInformationj+0x38)[0x7fbf85c8a890]<br>[node0:55292] [11] /opt/OpenFOAM/ThirdParty-5.0/ParaView-5.4.0/build/lib/libvtkPVServerImplementationCore-pv5.4.so.1(_ZN16vtkPVSessionCore17GatherInformationEjP16vtkPVInformationj+0x8d)[0x7fbf85c8ab45]<br>[node0:55292] [12] /opt/OpenFOAM/ThirdParty-5.0/ParaView-5.4.0/build/lib/libvtkPVServerImplementationCore-pv5.4.so.1(_ZN16vtkPVSessionBase17GatherInformationEjP16vtkPVInformationj+0x3e)[0x7fbf85c866fc]<br>[node0:55292] [13] /opt/OpenFOAM/ThirdParty-5.0/ParaView-5.4.0/build/lib/libvtkPVServerImplementationCore-pv5.4.so.1(_ZN18vtkPVSessionServer25GatherInformationInternalEjPKcjR21vtkMultiProcessStream+0xb7)[0x7fbf85c974b9]<br>[node0:55292] [14] /opt/OpenFOAM/ThirdParty-5.0/ParaView-5.4.0/build/lib/libvtkPVServerImplementationCore-pv5.4.so.1(_ZN18vtkPVSessionServer24OnClientServerMessageRMIEPvi+0x561)[0x7fbf85c97225]<br>[node0:55292] [15] /opt/OpenFOAM/ThirdParty-5.0/ParaView-5.4.0/build/lib/libvtkPVServerImplementationCore-pv5.4.so.1(+0xa537a)[0x7fbf85c9537a]<br>[node0:55292] [16] /opt/OpenFOAM/ThirdParty-5.0/ParaView-5.4.0/build/lib/libvtkParallelCore-pv5.4.so.1(_ZN25vtkMultiProcessController10ProcessRMIEiPvii+0x356)[0x7fbf826a06ea]<br>[node0:55292] [17] /opt/OpenFOAM/ThirdParty-5.0/ParaView-5.4.0/build/lib/libvtkParallelCore-pv5.4.so.1(_ZN25vtkMultiProcessController11ProcessRMIsEii+0x6b5)[0x7fbf826a02bb]<br>[node0:55292] [18] /opt/OpenFOAM/ThirdParty-5.0/ParaView-5.4.0/build/lib/libvtkPVClientServerCoreCore-pv5.4.so.1(_ZN26vtkTCPNetworkAccessManager21ProcessEventsInternalEmb+0x46d)[0x7fbf85986311]<br>[node0:55292] [19] /opt/OpenFOAM/ThirdParty-5.0/ParaView-5.4.0/build/lib/libvtkPVClientServerCoreCore-pv5.4.so.1(_ZN26vtkTCPNetworkAccessManager13ProcessEventsEm+0x28)[0x7fbf85985ea2]<br>[node0:55292] [20] ./pvserver[0x401acb]<br>[node0:55292] [21] ./pvserver(main+0x25)[0x401b7f]<br>[node0:55292] [22] /lib64/libc.so.6(__libc_start_main+0xea)[0x7fbf7e2e088a]<br>[node0:55292] [23] ./pvserver(_start+0x2a)[0x4017ca]<br>[node0:55292] *** End of error message ***<br><br></blockquote></div><div><div><div><br>-- <br><div class="gmail_signature"><div dir="ltr">Thanks,<div>Gavin Ridley</div></div></div>
