Hello,
phase_000 is just a Simics checkpoint -- only architectural state is contained,
thus caches are empty as you pointed out. The number of flexpoints you need to
skip in order to reach a warmed-up state depends on the workload (you usually
need to skip more than one). If you are using one of our workloads, the
flexpoints that are skipped are already defined in the .run_job.rc.tcl file.
For example:
{ flexus_test_app_v9 baseline 0:18-28
$simics_commands(timing_commercial) }
tells the timing simulator to skip flexpoints 1 to 17 and only use 17-28.
If you have ported your own workload, you can estimate how many cycles you
roughly need to warm up your caches (depending on their size and your
workload's behavior) and then refine your estimation by looking into the cache
statistics on each flexpoint.
Hope this helps.
Regards,
Alexandros

Subject: Is cache empty when start a next flexpoint ?
Hi , all
When create flexpoints for from phase_000, the cache is empty at the beginning
for take the first flexpoint. But I am not sure that whether cache is still
empty when start to get the next flexpoint. Can anyone give me some hints?
Look forward your reply.
