Thank you both for your response :)
@Nikos: Yes, this is how I have implemented the various policies. 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
