// Class: ResultDatabase

//
|
|
// Purpose:
|
|
// Track numerical results as they are generated.
|
|
// Print statistics of raw results.
|

// Programmer: Jeremy Meredith

// Creation: June 12, 2009

|
// Modifications:
|
|
// Jeremy Meredith, Wed Nov 10 14:20:47 EST 2010
|
|
// Split timing reports into detailed and summary. E.g. for serial code,
|
|
// we might report all trial values, but skip them in parallel.
|
|
//
|
|
// Jeremy Meredith, Thu Nov 11 11:40:18 EST 2010
|
|
// Added check for missing value tag.
|
|
//
|
|
// Jeremy Meredith, Mon Nov 22 13:37:10 EST 2010
|
|
// Added percentile statistic.
|
|

|
|
// Jeremy Meredith, Fri Dec 3 16:30:31 EST 2010
|
|
// Added a method to extract a subset of results based on test name. Also,
|
|
// the Result class is now public, so that clients can use them directly.
|
|
// Added a GetResults method as well, and made several functions const.
