6. Other information

6.1 Median results

For a reportable SPECaccel run, three iterations of each benchmark are run, and the median of the three runs is selected to be part of the overall metric. In output formats that support it, the medians in the result table are underlined in bold.

6.2 Run order

Each iteration now consists of running each benchmark in order. For example, given benchmarks "910.aaa", "920.bbb", and "930.ccc", here's what you might see as the benchmarks were run:

    Running (#1) 910.aaa ref base oct09a default
    Running (#1) 920.bbb ref base oct09a default
    Running (#1) 930.ccc ref base oct09a default
    Running (#2) 910.aaa ref base oct09a default
    Running (#2) 920.bbb ref base oct09a default
    Running (#2) 930.ccc ref base oct09a default
    Running (#3) 910.aaa ref base oct09a default
    Running (#3) 920.bbb ref base oct09a default
    Running (#3) 930.ccc ref base oct09a default

When you read the results table from a run the results in the results table are listed in the order that they were run, in column-major order. In other words, if you're interested in the base scores as they were produced, start in the upper-lefthand column and read down the first column, then read the middle column, then the right column.

If the benchmarks were run with both base and peak tuning, all base runs were completed before starting peak.
