- Build a direct execution CPU model based on the Linux Kernel Virtual Machine
 -  Parallelize M5
- Use the Wisconsin Wind Tunnel as a guide
 
 - Crossbar network
 - Mesh network
 - Directory Protocol
 -  Real F/S In-order core
- Kevin has one that works to some degree in SE, it doesn't have functional units yet, but it does have variable latency stages and such
 - Korey has one he did at MIPS, I don't know about it's features, but it's SE only as well
 
 -  Fast Simple Core
- This largely disregards all the compartmentalization we've done. It touches a lot of things, so the time to start being productive would be high
 
 -  Instruction page decode cache
- Kinda goes along with the fast simple core, but i think it's a more manageable task. Clearing it is as simple as looking for flush instructions in sparc and the correct pal trap in alpha
 
 -  SMT
- Fix O3 bugs/ Fix ROB Units
 - It's a huge pile of code to understand before you get anywhere if they get that far
 
 -  Are there any other benchmarks we want?
- That they could possible make work?
 
 -  Devices?
- Validate the DRAM model?
 
 -  Sampling/checkpointing/restarting
- Testing, fixing, etc... Not exactly exciting work
 
 - Write a PLI interface to connect Verilog CPUs to the memory system.
 - Sampling/fast-forwarding techniques (making sure ours works, maybe adding in some new ones)
 - Different cache models (different replacement policies, etc.; would allow them to do some research into it, maybe get some work done for Lisa)
 - Different prefetcher models (expand on what Ron has, also can do some research into it)
 - Flash memory device model? (seems popular nowadays)
