Unfortunately we haven't done a gentoo cluster, though with portage |
2 |
maintenance would be easy. I did want to comment on your processor choice. If |
3 |
you choose quad core your only option currently is Intel clovertown. These |
4 |
machines are power hungry. I would reccomend waiting for the opteron quad |
5 |
core chips that will be comming out in 07. If your going dual core I would |
6 |
reccomend opterons. They don't require the fully buffered dimms which from |
7 |
our testing seem to draw about 15W per dimm. The other thing to consider is |
8 |
the characteristics of your code, what we have seen from the Intel cpus is |
9 |
jobs run quite well if they are serial jobs, however when running parallel |
10 |
jobs the opterons still win out. |

Just some food for thought .... |
