Site A Site B Site C Site D Observations 1. The poverty line emerges surprisingly quickly in some cases For example, Site C's performance poverty line starts at 400 milliseconds. For some sites (such as Site C), the difference was as little as 300 milliseconds. That's early! seconds to work toward.

Some opinions claim that “Benchmarks are meaningless”, “benchmarks are irrelevant” or “benchmarks are nothing like your real applications” However for others “Benchmarks matter,” as they “account for the processing architecture and speed, memory, storage subsystems and the database engine.”

Instead, focus on understanding what the workloads exercise to help us determine how to best use them to aid our performance assessment. Benchmarking the target Two of the more popular database benchmarks for MySQL are HammerDB and sysbench. We will not concern ourselves with the raw throughput of workload. 4.22 %usr 38.40

The exercise seemed simple enough — just fix one item in the Colfax code and we should be finished. Published DGEMM benchmark results for the Xeon Phi 7250 processor ( [link] ) show maximum values of about 2100 GFLOPS when using all 68 cores (a very approximate estimate from a bar chart). Instead, we found puzzle after puzzle.

There was no deep goal — just a desire to see the maximum GFLOPS in action. The exercise seemed simple enough — just fix one item in the Colfax code and we should be finished. Instead, we found puzzle after puzzle.
