Caching Strategies for DiskRAM

This page discusses possible caching strategies that we can try to use with DiskRAM.

There is also a list of questions on Chris' Dissertation Ideas.

- The write-back policy on the L2 cache can make applications with a small memory footprint run slower, because there is more room for dirty blocks that must be evicted.

A Case for Multi-Level Main Memory (Ekman & Stenstrom, 2004)
- Points to the trend that the number of threads running on a machine is increasing, and thus, the need to have larger main memory(DRAM). This leads to problems with size, cost, and power.
- They suggest using Levels in Memroy, the first level a normal DRAM, the second and greater levels can be compressed or powered down to save power comsuption.
- Results are simulated.
- Did they look into using a disk with smarter paging to support more threads???
