Hello,
I believe it has to do with initializing some critical parameters of the simulator. You can find a short description here https://sos.ece.cmu.edu/pipermail/simflex/2009-June/000505.html , but this post is targeted for the process described in the Getting-Started-Guide. Run one of your jobs interactively and check the output to see what parameters need to be initialized for your simulator to work. Set their values in the configuration file (user-postload.simics I believe) and re-run. Let us know if you have any more questions.

I made the replacement policy an external parameter so that I can modify it through the configuration file. I have one more question though: I have created phases and flexpoints for db2v8_tpch_qry17_16cpu workload successfully however when i try to actually run the timing simulation using the command: run_job -run timing CMPFlex db2v8_tpch_qry17_16cpu (with the default empty user-postload.simics scripts) I get this error: 59 <ConfigurationManager.cpp:106> {0}- <undefined> Assertion Failed: ((!(false))) : ERROR: Not all parameters were initialized, and initializeParameters() indicates that they should be. Abort (SIGABRT) in main thread. The simulation has been corrupted. Simulation cannot continue. Do you know what might be the problem? Thanks for your time! Christina 2009/7/9 Nikos Hardavellas <hardav at cs.cmu.edu> Christina, Some more info on your request: We have implemented hooks for replacement policies in components/Cache/NewCacheArray.*pp The replacement policy is passed as a parameter when instantiating a cache controller at components/Cache/CacheController.hpp. We didn't make the parameter externally visible, so you cannot set it through user-postload.simics. You can either implement your policies and instantiate the controller with the appropriate parameter, or make the replacement policy an external parameter that you can set through user-postload.simics (it is quite easy to do so).

Given you are seeing a discrepancy with the replacement policy, I would guess that one of your simulators is a CMP and the other one is not. If the parameter exists, you can definitely set it through the user-postload.simics file. As for the replacement policy, do you want to modify the policy, or do you just want to get your simulator working? In general, only the LRU policy is thoroughly tested. That said, if you wish to develop your own replacement policy, I would recommend that you start with looking at the hooks that currently exist in the code.
