| 71 | | ==== IMPORTANT: Use hardware acceleration in your VNC session |
| 72 | | |
| 73 | | '''vglrun''':\\ |
| 74 | | Any OpenGL application running in your VNC session should be started with '''vglrun''' to use the hardware acceleration provided by the visualization nodes. |
| 75 | | |
| 76 | | ==== e.g. ParaView |
| 77 | | Open a terminal in your VNC session and: |
| 78 | | {{{ #!sh |
| 79 | | # What versions of ParaView are available? |
| 80 | | module spider ParaView |
| 81 | | |
| 82 | | # load ParaView dependency |
| 83 | | module load intel-para |
| 84 | | |
| 85 | | # load ParaView |
| 86 | | module load ParaView |
| 87 | | }}} |
| 88 | | |
| 89 | | {{{ #!sh |
| 90 | | # start ParaView Server and GUI using VirtualGL for hardware acceleration |
| 91 | | srun -n 24 vglrun pvserver |
| 92 | | vglrun ParaView |
| 93 | | }}} |
| 94 | | Connect to the pvservers on localhost:11111 |
| 95 | | |
| 96 | | ==== e.g. !VisIt |
| 97 | | Open a terminal in your VNC session and: |
| 98 | | {{{ #!sh |
| 99 | | # change Stage |
| 100 | | module use /usr/local/software/jureca/OtherStages |
| 101 | | module load Stages/.Stage1 |
| 102 | | |
| 103 | | # What versions of VisIt are available? |
| 104 | | module spider VisIt |
| 105 | | |
| 106 | | # load VisIt dependency |
| 107 | | module load intel-para/2015.07 |
| 108 | | |
| 109 | | # load VisIt |
| 110 | | module load VisIt/2.10.0 |
| 111 | | }}} |
| 112 | | |
| 113 | | {{{ #!sh |
| 114 | | # start VisIt using VirtualGL for hardware acceleration |
| 115 | | vglrun visit -hw-accel |
