#4105 — But here is more benchmarks about relaxed memory models compared to SC model

Hello..

Read this:


I have posted in my previous post that:

Memory Models: x86 is TSO, TSO is "Good"

But here is more benchmarks about relaxed memory models compared to SC 
model:


Read carefully:

Architecture Support and Scalability Analysis of Memory
Consistency Models in Network-on-Chip based Systems

"From the experiments, it can also be observed that the reduction in the 
relative execution times under relaxed memory models like WC, RC, and 
PRC over the SC model is expected to be 3.33 percentage points 
approximately for each doubling of the core count up to 128 cores. The 
relaxed memory models could exploit the increasing parallelism in
the larger networks beyond the 64-cores by reordering and pipelining the 
memory operations. Similarly, for the TSO and PSO models Figure 4.37 
suggests that this can be projected to 1.0 percentage points for each 
doubling of the core count up to 128 cores. In general, the performance 
gain of the relaxed memory consistency models can be even
higher than the experimental values when the system size is further 
increased.
