Go up one level in this thread


here's the speedup test results from dual G5 (2 GHz)
crafty-19.10f

best   speedup = 3.32
worst speedup = 0.89

mt=2a	mt=2b	mt=2c	mt=2d
		  speedups
====================
1.88	1.52	1.87	1.54
2.04	1.91	1.96	1.96
1.77	1.79	1.77	1.76
1.96	1.60	1.48	1.78
2.92	2.92	2.77	2.92
2.20	1.84	1.92	1.78
1.87	1.87	1.87	1.87
1.56	1.62	1.73	1.64
1.76	1.62	1.79	1.69
1.83	1.77	1.92	2.04
2.03	2.32	1.90	2.17
1.67	1.52	1.92	1.85
1.12	1.08	1.45	1.99
3.26	3.39	3.27	2.29
1.29	1.20	1.30	1.31
1.33	1.57	1.42	1.45
1.51	1.55	1.99	2.08
1.71	1.91	1.36	2.10
1.54	2.67	2.21	3.32
2.28	2.28	2.69	2.86
1.45	2.17	1.55	2.00
1.40	2.01	0.89	1.56
1.53	1.69	1.65	1.52
2.28	1.43	1.43	2.41
====================
1.84	1.89	1.84	2.00	mean speed-up
0.50	0.53	0.51	0.49	stdev of mean speed-up

results seem to match expected values; perhaps slightly higher than the Xeon
tests
because the memory interface is faster
