Summary | 0013051: Slow Rendering Performance when using OpenGL (Hardware Rendering) and MPI | ||||||||
Description | Summery: When using ParaView in parallel with either MVAPICH2 or OpenMPI and hardware rendering (nVidia Quadro 5000/6000, Tesla C2050 tested), rendering performance drops significantly. Problem reproduced using a VTK test program and when running on a single node with MPI simply linked to the executable (no composting occurring). Notes: 1) Have ruled out composting as the issue by running on one node with MPI simply linked but not invoked (no mpirun or mpiexec called). 2) No X forwarding or Mesa in play on the systems exhibiting this issue. 3) Immediate mode rendering toggled on and off with no effect when test data set loaded into PV GUI. To Reproduce: 1) Build ParaView w\ MPI support and OpenGL support for the installed graphics card. 2) Issue a pvbatch job with timer logs to capture run time. Recompile PV w/o MPI and re-time. 3) Convert the pvbatch job to a VTK C++ program. Link against vtkRendering and time execution. Relink program against vtkParallel and time execution. Results Seen (VTK Program w\ MPI and 4 million triangles): HP DL585 compute node w\ Quadro 5000, MVAPICH2: ~10 fps HP Z800 workstation w\ Quadro 6000, OpenMPI: ~4 fps HP Z800 workstation w\ Tesla C2050, OpenMPI: ~2.5 fps Results w/o MPI Linked for DL585 Compute Node, 4 million triangles: 0000162:0000114 fps | ||||||||

Tracking system incorrectly transformed the last line into a link. Original Text: Results w/o MPI Linked for DL585 Compute Node, 4 million triangles: ~ 114 fps |

Re-ran tests with the following nVidia driver versions: - 260.1936 (release date: 1/21/2011) - 275.43 (release date: 12/14/2011) - 295.20 (release date: 2/13/2012) - 295.33 (release date: 3/22/2012) Saw no change in rendering performance of MPI linked VTK test program between driver versions. |

Tested with MPICH2 version 1.4.1p1 (no IB support) and found that no performance hit was taken. Appears to narrow the problem to a conflict with OFED and/or the IB-enabled portions of MPI. |

I was able to reproduce it and run various performance tests. Also I ran my tests on ATI cards and found no noticeable difference in performance. We are working towards a solution. |

I submitted a report after extensive testing. |
