+
+Timings are given in seconds, computed using the C library's clock()
+function. The first column gives the hardware and compiler
+configuration used for the test. The second column indicates the
+number of tests that were aggregated to get the statistics for that
+size. These were compiled using 16 bit digits.
+
+Source data were generated randomly using a fixed seed, so they should
+be internally consistent, but may vary on different systems depending
+on the C library. Also, since the resolution of the timer accessed by
+clock() varies, there may be some variance in the precision of these
+measurements.
