Translating Timing into an Architecture: The Synergy of COTSon and HLS (Domain Expertise—Designing a Computer Architecture via HLS)

Figure 12

Total number of cycles in the COTSon framework when using the matrix multiplication benchmark with 512 as the matrix size and 32 KiB as the cache size. We varied the number of nodes of the distributed system and the Linux distribution (“xenv0” = Ubuntu 16.04, “karmic64” = Ubuntu 9.10, “trusty-axmv3” = Ubuntu 14.04, and “tfxv4” = Ubuntu 10.10). The DSE allows us to determine that the four Linux distributions permit to obtain a good scalability when we increase the number of nodes. However, the “xenv0” confirms the worst performance in terms of executed cycles due to the huge number of kernel cycles shown in Figure 11.
