Hi Tamas! |

I can not contribute much to this specific case. I only have experience with dual core HP Opteron Blades. All I can say is, that there is no recognisable speed penalty compared to the same number of cores with single core CPUs. |

Betreff: [gentoo-server] experiences with Gentoo on a Tyan Thunder K8QW (S4881)? |
| 20 |
|
| 21 |
Dear all, |
| 22 |
|
| 23 |
Do you have any experience with parallel computations on an S4881 with 4 single or dual core Opterons? The goal is to have a system flexible enough to run |
| 24 |
- a single thread job using all the available memory and |
| 25 |
- one or more multithreaded jobs sharing the physical RAM. |
| 26 |
I hope these two extremes cover the cases of future simulations. |
| 27 |
|
| 28 |
What are the limitations? Are there problems like missing (eg. by-BIOS |
| 29 |
PCI-asigned) half gigs as with other mobs? Speed penalties with special RAM-populations? Scaling? Experiences with the extension to 8 processors, single core vs. dual core? Etc... |
| 30 |
|
| 31 |
I have good experiences with Gentoo on dual Athlon and Opteron systems, as well as with dual core Intel Centino so I just want to be sure before suggesting the S4881+Gentoo combination... |
| 32 |
|
| 33 |
Any hints are welcome, |
| 34 |
Tamas |
