I just converted out 134 node cluster from RedHat Enterprise Linux v4 |
| 2 |
to Gentoo 2005.1 |
| 3 |
|
| 4 |
Before and after the conversion we ran UnixBench as part of the |
| 5 |
Beowulf Performance Suite. |
| 6 |
|
| 7 |
There is a graphical representation of the results here: |

That shows Gentoo and Redhat on x86 hardware, and Gentoo and Macos on |
| 11 |
an dual XServe G5. |
| 12 |
|

And here is the tables: |
