*         labelled whenever they are published.  Examples of
*         proper labelling include:
*         "tuned BabelStream benchmark results"
*         "based on a variant of the BabelStream benchmark code"
*         Other comparable, clear and reasonable labelling is

* Run Rules:
*
* In order to generate a valid BabelStream result measuring
* *main memory bandwidth*, you should obey the following rules:
*
* 1. The array size must be large enough that increasing the array size does not
* drastically change the reported bandwidth. If you satisfy this you will no
* longer be affected by any cache effects.
*
* 2. Each kernel should take a few milliseconds. The resolution of the host timer
* is probably in milliseconds so each kernel execution should be longer than the
* timer resolution. Increase the array size if the kernels are too fast. You are
* unlikely to break this rule if you follow rule 1.
*
* If you see a single BabelStream result, expect this to be the largest bandwidth
* reported by the benchmark unless stated otherwise.
