Dear all, 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 - a single thread job using all the available memory and - one or more multithreaded jobs sharing the physical RAM. I hope these two extremes cover the cases of future simulations.
What are the limitations? Are there problems like missing (eg. by-BIOS 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... 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... Any hints are welcome, Tamas -- [email protected] mailing list
