These tests test the total time taken to execute all of Boost.Math's test
|
||
cases for these functions. In each case the best performing library gets
|
||
a relative score of 1, with the total execution time given in brackets. Times
|
||
are shown for both single threaded runs and concurrent execution - the latter
|
||
increases contension inside new/delete.
