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
26
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
27
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
28
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
29
iHDTV™ iHD1500 iHD1500 Optiportal Integration: Overlay Option resulted in a nice render-to- screen 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
30
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
