Problem

1. A Dash system has b bytes of memory divided over n clusters. Each cluster has p processors in it. The cache block size is c bytes. Give a formula for the total amount of memory devoted to directories (excluding the two state bits per directory entry).

2. Is it really essential that Dash make a distinction between the CLEAN and UNCACHED states? Would it have been possible to dispense with one of them? After all, in both cases memory has an up-to-date copy of the block.
