Evaluating the Evaluation: A Benchmarking Checklist

Brendan Gregg

These have inspired me to summarize another performance activity: evaluating benchmark accuracy. Accurate benchmarking rewards engineering investment that actually improves performance, but, unfortunately, inaccurate benchmarking is more common. I have spent much of my career refuting bad benchmarks, and have developed such a knack for it that prior employers would not publish benchmarks unless they were approved by me. These kinds of benchmarks are misleading.

Memory Bandwidth Requirements of the HPL benchmark

John McCalpin

The High Performance LINPACK (HPL) benchmark is well known for delivering a high fraction of peak floating-point performance. The (historically) excellent scaling of performance as the number of processors is increased and as the frequency is increased suggests that memory bandwidth has not been a performance limiter. But this does not mean that memory bandwidth will *never* be a performance limiter.

Faster remainders when the divisor is a constant: beating compilers and libdivide

Daniel Lemire

We also published our benchmarks for research purposes. The paper contains carefully crafted benchmarks, but I came up with a fun one for this blog post which I call “fizzbuzz” Let us go through all integers in sequence and count how many are divisible by 3 and how many are divisible by 5. I make my benchmarking code available. Not all instructions on modern processors cost the same.

More fun with fast remainders when the divisor is a constant

Daniel Lemire

As a benchmark, I am going to compute a linear congruential generator (basically a recursive linear function with a remainder thrown in), using these three approaches, plus the naive one. In software, compilers can often optimize away integer divisions, and replace them with cheaper instructions, especially when the divisor is a constant. I recently wrote about some work on faster remainders when the divisor is a constant.
