Hi, I have started using the xeon for large intensive jobs. However, only 1 core runs at 100percent. The rest at ~20. My software is for all 8cores. The developer says it's a Linux issue.

On reading it appears Ubuntu isn't ready for 8cores by default and I need to rebuild the kernel. This isn't a prob. However, before starting will someone pls tell me is it ok to find the current ker. source and re configure rather than worry about supporting all necessary drivers in a new file?

Or, is there a better Linux distro for parallel use? I used Gentoo for years so rebuilding is easy. But will someone advise me on this since I don't want any mistakes with Ubuntu?

Thank you. Gav.

The process should be pretty much the same - just install the kernel source package: sudo apt-get install linux-source and carry on from there. If you have any questions along the way, feel free to ask.

I also suggest installing kernel-package which lets you build a .deb package of your new, custom kernel.
