Re: [Gems-users] Read and write misses

[<adash@xxxxxxx>]

I'm planning to add a function:
void miss_profile(const CacheMsg& msg, NodeID id) in
Profiler.C to account 
for read and write misses. Also, I noticed that a function in
Sequencer.C 
(doRequest(const CacheMsg& request)) that can be used to find
out a cache 
hit and hence read or write miss. I have the following questions:
o How do I access doRequest() inside Profiler.C (Do I need to 
instantiate a Sequencer object ?)
o Is this the right way of finding out miss statistics -or- is
there any 
other way to calcuate the same inside Profiler.C ?
