Remote Visualization

Ravi Chityala Mike Knox

Nancy Rowe


Remote visualization •  Motivation: Large data

–  Limited local storage –  Lengthy data transfer time –  Slow local graphics system

•  Data rendered where calculated •  Challenges:Bandwidth

–  1280 x 1024 pixels of 24 bits at 30 frames a second = 118 MBps

•  Latency of network and GPU


What is remote visualization at MSI?

•  Available on Jay and Koronis •  Several ways to access •  Experimental


Systems Jay •  Nvidia Quadro FX5800 •  64G memory Koronis (SGI Altix UV Constellation); NIH

graphics[2-4] •  Nvidia Quadro FX5800 •  48G memory

graphics1 •  Nvidia Quadro FX1800 •  256G memory


Access to Systems Jay •  Reservation •  qsub -I -q jay •  www.msi.umn.edu/hardware/itasca/jay.html

Koronis   NIH   www.msi.umn.edu/hardware/koronis


Systems System Location of

temporary storage

Single Read/Write speed

Aggregate Read/Write speed

Jay /lustre ~400MB/s ~400MB/s

~10GB/s ~13.5GB/s

Koronis /scratch ~1.5GB/s ~1.5GB/s

~4 - 14GB/s ~7- 16GB/s (highly variable)


Ways to access •  KVM •  Teradici •  VirtualGL •  Client/Server


KVM •  Keyboard, Video and Mouse •  Directly runs software •  Installed in SDVL 575


Teradici card •  PCoIP •  Host rendering •  Just sends pixels •  Installed in SDVL 575


VirtualGL (VGL) •  Open source •  OpenGL •  Linux server •  Requires local client – Linux, Windows, Mac •  Images rendered on remote computer •  2D graphics done locally •  Applications not vendor supported


Software •  Avizo •  Ensight •  Custom software


Avizo •  General purpose visualizer •  VGL •  Scripting


Ensight •  Engineering data •  VGL •  Client/Server


VirtualGL Installation •  Browse to the download page:

–  http://www.virtualgl.org/Downloads/VirtualGL

•  Pick an appropriate installation package –  Architecture: i386 / amd64 –  OS: .exe / .rpm / .deb / .dmg

•  Follow the OS specific installation instructions: –  http://virtualgl.svn.sourceforge.net/viewvc/virtualgl/vgl/trunk/doc/index.html#hd004
