Why do benchmark results vary at all?

Benchmarking typically consists of getting the current CPU time, executing test code a large number of times, and then subtracting the new CPU time from the previous one. However when you benchmark ...

Benchmark of SAT solvers on random k-SAT instances at satisfiability threshold

I am looking for a solid reference (peer-reviewed publication) on the design and/or benchmarking of SAT solvers for random k-SAT ($4 \leq k \leq 8$) operating at satisfiability threshold. The majority ...

Where can I find some free benchmarks to evaluate a MCU? [closed]

At present, I'm designing a soft processor with single-precision floating point unit (FPU). I am going to put my soft core into an FPGA and do some performance evaluation. The benchmarks are supposed ...

Is the data-centric "push" model for SQL evaluation nonsense?

The traditional way to implement a SQL database is to parse the query, create a parse tree, and then evaluate it using the "volcano" model. In this model you call .next() on the root node of the tree ...

How to evaluate metrics or benchmarks?

How would you evaluate a new metric or benchmark? My concrete example: I want to benchmark code review. As others did [1, 2] , one can apply metrics from social network analysis (such as centrality, ...

Why do I get really different results with my benchmarking code I made?

I'm doing research work for my last year in high school. My work is about processors and for the experimental part i've coded an app that can mesure how many Floating Point Operation can a processor ...

Does a PC age in terms of hardware and performance? [closed]

Let's say you are using a personal computer for 10 years. Assuming all software things are the same, will the computer get the same scores on benchmarks as 10 years ago? If not, why?

What are good algorithms for virtual machine benchmarking?

I am comparing execution efficiency of the same code compiled to JVM and Node, locally and on AWS Lambda. Not looking for precision, but just a rough notion of performance in difference virtual ...

Strategy to create a testbed and gold standard

I need to create a correct evaluation of the method I'm proposing. The problem is that in the field I'm working on there is no benchmark that I can use for this purpose. On the other hand, my method ...

How are benchmarks created?

Computing equilibria in games and the complexity thereof is imho still quite a young field in which a lot of work still is to be done (especially the former). GAMUT (2004) is a very nice "suite of ...

Interesting small SAT problems?

I'm noodling around with making a hardware SAT solver on an FPGA, and I'm wondering if there are any interesting SAT problems smaller than, say, 50 variables both to stay within the limits of the FPGA ...
