One of the big distributed computing projects is the RC5 key breaking contest put on by the RSA Labs and performed by distributed.net. To participate in te contest, you download the latest distributed.net client, and let it run on your machine(s). The client will then use as much free CPU power as possible to try and crack the key. The faster CPU, the more keys per second your machine can test, therefore I made this page to showcase the different speeds of some of my computers. Other people's test results can be seen here.
- Test Systems:
- Beige G3 233 upgrade to 500 MHz, Mac OS X 10.2.8
- Dual USB iBook G3 500 MHz, Mac OS X 10.3.3
- Digital Audio G4 466 MHz, Mac OS X 10.3.2
- G5 Dual 2 GHz, Mac OS X 10.3.3
| Computer | Contest | Client Version | Keys per second |
| 1 | RC5-72 | 2.9007.488b | 1.7 Million |
| 2 | RC5-72 | 2.9007.488b | 1.7 Million |
| 3 | RC5-72 | 2.9007.488b | 4.2 Million |
| 4 | RC5-72 | 2.9007.488b | 29.8 Million |
- Notes
- It's interesting to see how much Atlivec can affect the performace of applications. Here, we see a lower MHz G4 beat out the G3 by a very large ammount, simply due to using Altivec.
- The G5 Processor Performance Setting makes no difference with this program when using High or Automatic.
- See my overall RC5-72 stats here: My Stats (1 block has 2^32, about 4.3 billion, keys)
