CATALYST \has developed new, high-speed, orthorectification functions. The code takes advantage of modern, multi-core processor architecture, as well as NVIDIA’s Graphical Processing Units (GPUs), to process standard data products from the WorldView-1, QuickBird and IKONOS satellites.
Even with no GPUs on board, the system can process 1.75 TB per day as a result of multithreaded processing and improved IO. Using a single GPU, the improvement was still 6 times faster than the Catalyst ortho PPF, and 1.5 times faster than a non-GPU, multi-threaded implementation. This demo shows the potential of the GPU in speeding up problems that are computationally intensive in CATALYST’s field of business (DEM creation, image matching, pan-sharpening).
The CATALYST Enterprise system can be deployed on the Cloud much in the same way a non-cloud based CATALYST Enterprise system. The main difference is that there is no need to purchase any physical hardware in order to configure a CATALYST Enterprise system that can achieve the stated throughput requirements. Catalyst nonCloud based CATALYST Enterprise systems are typically deployed on desktop or rack mounted systems, which include a certain set of hardware specifications, including (Catalyst would specify which hardware to purchase): – CPU / GPU – RAM – Disk Storage – UPS – File Server – Network Switch – Operating System
