Fig. 8. Performance of G-HPL on Westmere and Sandy Bridge In Figure 9, we show memory bandwidth for each system using the EP-Stream Triad benchmark. 8% higher for Sandy Bridge due to faster memory speed (1600 vs. 5 MB vs. 2 MB per core; 25% larger cache on Sandy Bridge). 6 GB/s due to memory contention. 4 GB/s per node = 2 processors x 4 channels x 8 bytes x 1600 MHz per processor). The faster memory bus enables Sandy Bridge to deliver both higher peak-memory bandwidth and efficiency, producing significant advantages for memory-intensive codes.
Nek5000) can have diﬀerent reuse distance distributions. It is important to investigate the full application to understand data locality. 3. Proxy applications and benchmarks tend to have higher rates of SIMD instructions because complex memory access patterns have been removed from compute-intensive loops, and the compiler can optimize and identify SIMD optimizations with higher clarity. 4. Finally, the communication topologies that we measured show that some of the proxy apps do not necessarily represent the communication behavior of the application they are intended to model.
