We are trying to study some datacenter applications and are trying to get cloudsuite to work under Marssx86.
We have some of the benchmarks from cloudsuite running under Marssx86. However the simulated cache miss rate results seem to be very different from cache miss rates obtained from native hardware using perf (e.g., for memcached the native L1 miss rates are ~ 15%, whereas we observe only ~ 3%). The setup we are using for simulation is to have the server workload running in a single threaded simulated machine while we run the load generators from outside and we use qemu's user mode networking. You mentioned in your MICRO 2012 tutorial that the work to simulate cloudsuite under Marssx86 is ongoing. Is that work done? If yes, is it possible for us to gain access to the necessary steps for simulating cloudsuite on Marssx86, and/or the disk images used by you? -- Thanks, Subhasis
