iHDTV™ iHD1500
 iHD1500 Optiportal Integration:
 Goal to place live HD video in OptIPortal
Window from iHDTV application
 Non-typical OptIPortal hardware required
 Some modification of iHD and SAGE required
• SAGE = Scalable Adaptive Graphics Environment
 Successfully demonstrated at SC07
iHDTV™ iHD1500
 iHD1500 Optiportal Integration:
 iHDTV+SAGE option
• Cause iHDTV to output to the composite display using
SAGE as an “off-the-shelf” library to handle image
splitting
 Overlay Option
• Run an instance of iHDTV on each SAGE display
node
Send a pre-split picture to each node along with display
information
iHDTV™ iHD1500
iHD1500 Optiportal Integration:
 iHDTV+SAGE option contstraints
• Images had to be kept small to aviod distributing the
load across the entire display system
• Support for 2gige NICs had to be built into SAGE
• 10gige or Infiniband not possible at the moment
• Enable jumbo frames on all SAGE interfaces
• Modify iHDTV to use the SAGE library
iHDTV™ iHD1500
 iHD1500 Optiportal Integration:
 Hardware requirements
• Intel Core 2 Duo E6750 Conroe 2.66GHz
• EVGA 122-CK-NF63-TR motherboard
• 2 GB of PC3 10600 1333MHz memory
• Intel PRO 1000PT Dual Port PCI Express NIC
• PNY GeForce 8600GT 256MB PCI Express x16 video
card
• Specs similar to iHDTV node
iHDTV™ iHD1500
 iHD1500 Optiportal Integration:
 Overlay Option resulted in a nice render-toscreen function for iHDTV which will be
incorporated in the code base
 Support for multiple network interfaces required
running two instances of SAGE for each logical
half of each display
iHDTV™ iHD1500
 Suggested changes to SAGE:
• Modify the SAGE display manager to accept a
parameter specifying an IP address for binding sockets
• Modify the SAGE display manager to accept a
parameter specifying the position of its window relative
to the overall display
• Modify the code for the SAGE window manager to
accept per-node configuration for the above parameters
• Modify the SAGE code for determining the size of the
part of the image blanked out due to the physical frames
of each display.
• Use XVideo rather than OpenGL which would allow our
application to run 4 times faster in the Overlay Option
