(E) PowerBook G3 1 x PowerPC 750 266MHz MacOS 8.5.1

Compiler

(1) MIPSpro C 7.2.1 -O3 optimizations
|
||
|
|
(2) GCC 2.95.1 -O3 optimizations
|

|

(3) IBM AIX xlc -O3 optimizations (version unknown)

|

|

|
|
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.
