cache-replacement-policies-in-gem5

This repository contains patches written in C++ and python for implementation of LIP, BIP, DIP and SRRIP cache replacement policies in gem5. It also contains implementation of Victim Caches. gem5 is an open source simulator for Computer Architecture research. These "diff" patches can be directly applied to gem5 2012 version.

impica

This is a processing-in-memory simulator which models 3D-stacked memory within gem5. Also includes the workloads used for IMPICA (In-Memory PoInter Chasing Accelerator), an ICCD 2016 paper by Hsieh et al. at https://users.ece.cmu.edu/~omutlu/pub/in-memory-pointer-chasing-accelerator_iccd16.pdf

nvpage

The non-volatile memory such as PCM or NV-DIMM is coming. It makes possible that persistent data can be accessed in dram way. However, the current design of linux (page cache, no distinguish between dram and pram) will make trouble: software overhead and resouce usage. So it is necessary to make future OS support persistent ram by using a new foundational mechanism, which is the target of Project NVPage. In this project, we divide page to V-Page and NV-Page which can be recovered during reboot. There are two featrue we provided: 1. Kernal programmer only need declare a page as the NV-Page, and the recover work during reboot is transparent. 2. Kernal programmer only need declare a set of NV-Page increasingly when the set state is legal, the work to maintain consistency during power exception is transparent. The code of project consist of two part: one is modified Gem5 to support pram and the other one is modified linux kernal to support NV-Page.
