Comparing Different Computers with N Queens Program
--D. Thiebaut (talk) 11:05, 24 October 2014 (EDT)
This is an example of how one can get a quick comparison of the processing of different systems using a CPU-bound (not using disk or network) application. I used a java program that finds the solution to the N-Queens problem while counting the number of probes it makes to the 2-D board. The source code is available here.
Here are some results gathered in Oct. 2014 on several systems I have access to. NxN is the dimension of the board.
| NxN | Macbook Pro 2.8 GHz Core i7, 16GB 1600MHz DDR3 | MacPro 2009 | MacPro 2014 | Beowulf 2 |
