  1. Understanding Parallel Computers Parallel ProcessingEE 613

  2. Balancing Machine Specifics With Portability • How much do we need to know about the machine architecture • Performance goal • Game developers, embedded systems, and hardware vendors • Coding specific to machine • Lifetime goal • Portability • Generalized code

  3. A Look At Six Parallel Computers • Chip Multiprocessors • Intel Core Duo • AMD Dual Core Opteron • Heterogeneous Chip Designs • GPU, FPGA, Cell • Vector • Clusters • Node – processors, RAM, disk, memory not shared • Typical - eight nodes, control processor, switch • Blade server – includes com ports and cooling fans • Supercomputers – BlueGene/L (440 PowerPC’s)

  12. Both designs implement a coherent shared memory. CSE524 Parallel Algorithms Lawrence Snyder

  14. Symmetric Multiprocessor (SMP) • Each processor makes memory requests over the common memory bus • All cache controllers snoop the memory bus and adjust the tags on their cached values to ensure coherent cache usage.

  15. Example – po & p1 have copies of Block X, but p2 writes to Block X. CSE524 Parallel Algorithms Lawrence Snyder
