cse.240b Parallel Computer Architecture - Winter 2012      |
Course GoalsThis class is designed to enable students to follow the latest developments in computer architecture, especially those related to parallel computer architecture. Although this is clearly useful for those who wish to do research in computer architecture, it is also useful for those who work in related areas or who have general interests. The class strives for these goals through four aspects:
|
     |
|
Directory Coherence | Memory Consistency |
Interconnection Networks | Synchronization |
Transactions | Streams |
Vector Architectures | Heterogeneous Multi-core |
Simultaneous Multi-threading | Cell Architecture |
GPUs | Tiled Architectures |
CUDA | Cilk |
Arsenal Style Processors |

If dark silicon is replaced with cache, how much cache will the chips have? | |
