史上第一台完全用數位設計的客機，波音777。
聽說這個複雜到炸開的模型總共有350M triangle.....乘上4byte，這代表這東西光Model的vertex量就已經 1.4GB了，實際上的總模型資料量更高達29GB....然後IBM拿LLNL RoadRunner來搞real time ray tracing。
In the IBM booth at SC07 the 350M triangle Boeing digital mockup will be rendered real-time at 1080p resolution using a hybrid cluster of Cell processor based QS21 blades and a Ridgeback (AMD Opteron) memory server.
The Ridgeback holds the 25GB digital model in its memory and services blade data request via NFS RDMA over 2GB/sec InfiniBand.
Each blade is responsible for a dynamic region of the screen and therefore only requires a fraction of the digital model to be cached in its local 2GB memory.
These regions are further subdivided among the local SPEs which DMA via software caches from the address space of the Opteron forming a memory hierarchy that's transparent to the programmer.
