    GPU Technology Conference 2010 Sessions on Video Processing (subject to change) IMPORTANT: Visit www.nvidia.com/gtc for the most up-to-date schedule and to enroll into sessions to ensure your spot in the most popular courses. 2095 - Building High Density Real-Time Video Processing Systems Learn how GPU Direct can be used to effectively build real time, high performance, cost effective video processing products. We will focus especially on how to optimize bus throughput while keeping CPU load and latency minimal. Speaker: Ronny Dewaele, Barco Topics: Video Processing, Imaging Time: Thursday, September, 23rd, 16:00 - 16:50 2029 - Computer Vision Algorithms for Automating HD Post- Production Discover how post-production tasks can be accelerated by taking advantage of GPU-based algorithms. In this talk we present computer vision algorithms for corner detection, feature point tracking, image warping and image inpainting, and their efficient implementation on GPUs using CUDA. We also show how to use these algorithms to do real-time stabilization and temporal re-sampling (re-timing) of high definition video sequences, both common tasks in post-production. Benchmarking of the GPU implementations against optimized CPU algorithms demonstrates a speedup of approximately an order of magnitude. Speaker: Hannes Fassold, JOANNEUM RESEARCH Topics: Computer Vision, Video Processing Time: Wednesday, September, 22nd, 15:00 - 15:50 2125 - Developing GPU Enabled Visual Effects For Film And Video 1 The arrival of fully programable GPUs is now changing the visual effects industry, which traditionally relied on CPU computation to create their spectacular imagery. Implementing the complex image processing algorithms used by VFX is a challenge, but the payoffs in terms of interactivity and throughput can be enormous.

  • Storage Device Information 1
    Storage Device Information 1. MSI suggests to ask our local service center for a storage device’s approval list before your upgrade in order to avoid any compatibility issues. 2. For having the maximum performance of the SSD, see the suggested Stripe Size shown in the RAID 0 column to do the set up. 3. 2.5 inch vs. mSATA vs. M.2 SSD Which M.2 SSD Drive do I need? 1. Connector & Socket: Make sure you have the right combination of the SSD connector and the socket on your notebook. There are three types of M.2 SSD edge connectors, B Key, M Key, and B+M Key. – B key edge connector can use on Socket for 'B' Key (aka. Socket 2) (SATA) – M key edge connector can use on Socket for 'M' Key (aka. Socket 3) (PCIe x 4) – B+M Key edge connector can use on both sockets * To know the supported connector and the socket of your notebook, see the ‘M.2 slot(s)’ column. 2. Physical size: M.2 SSD allows for a variety of physical sizes, like 2242, 2260, 2280, and MSI Notebooks supports Type 2280. 3. Logical interface: M.2 drives can connect through either the SATA controller or through the PCI-E bus in either x2 or x4 mode. Catalogue 1.
