Message Passing Sharedmemory single copy of shared data in memory threads communicate by readingwriting to a shared location Messagepassing each thread has a copy of data in its own private memory that other threads cannot access threads communicate Although large caches can significantly improve performance they have the potential to increase power consumption As feature sizes shrink the dominant component of this power loss will be leakage However during a fixed period of time the activ ity i 00 2003 IEEE Published by the IEEE computer Society The next generation of todays high performance processors incorporate large level two caches on the processor die For example the IBM Power5 will contain a 192Mbyte L2 cache th caches and data caches are always identical in size or differ by a factor of 2X, but no more. The primary caches range from 8 KB to 128 KB with SA ranging from direct mapped to 8-way. Small instruct  Stefan . Schackow. Program Manager. Microsoft Corporation. PC41. What's the current state?.
