I think the code bases are so different at this point that I don't know how useful it is to try to list them, I can try to give you some of the biggest overall changes:
- PTLSim's user space simulation mode is completely removed - For full system mode, all of the Xen bindings and other super low level injection code is gone - MARSS can now run multi-CPU and multi-threaded simulations - The cache hierarchy has been made coherent for multithreaded workloads - The PTLStats implementation has been ripped out in favor of YAML stats which are human readable - Many of the configuration flags from the original PTLSim have been removed I'd say if you were reading the PTLSim manual, the superstl section and the section which describes the processor model details would still be relevant. Hope that's at least somewhat helpful. -Paul On Tue, Nov 15, 2011 at 9:06 PM, Ching-Tsun Chou <[email protected]>wrote: > I'd like to study the PTLsim part of MARSS source code.
