Support for future Intel server platforms
Ensure that Edgy supports forthcoming Intel server products including new chipsets, processors, architectures, technologies. This topic includes driver support for all typical peripherial H/W used with Intel servers in grid and high performance computing, such as fast NICs (Intel, 10Gb vendors, etc), HBAs (LSI, QLogic), interconnects (Infiniband, Myrinet,Quadrix, etc). The kernel changes would consider new power states, cpuids, instruction sets, cache hierarchy, etc.
This may also imply changes in kernel's OS scheduler, testing environment, MPI support, building the open source drivers for Ubuntu or requesting interconnect vendors to build a proprietary driver for ubuntu systems.

Whiteboard
Discussions with Ben Collins concluded on following steps:
- Ben will get latest Bensley/Woodcrest system by Supermicro in 2 weeks with 3.0Ghz CPUs
- May have issues with e1000 cards and SATA enhanced modes
- 2.6.17 kernel (Edgy) entirely supports new MC scheduler recognizing shared cache architectures
The testing may occur by Autotest tool, however new servers may not be accepted by IBM testing lab.
We have to see on how to construct the testing lab and what equipment from various H/W to get for the testing.
it would be difficult, or almost impossible to backport 2.6.17 kernel changes related to the new scheduler into 2.6.15, i.e. the Dapper. Will defer the decision after Edgy release candidate, depending on Edgy's stability state.
Ben received Bensley/Woodcrest (Core Duo 2 core) with 3GHz. Very fast machine. Need to bot in "safe video" mode due ATI problem (xorg-ati-driver bug). Need to disable DRI for RN50 chipsets (no acceleration). Bensley runs well under 2.6.17 kernel.
Can run Dapper live install and then upgrade to Edgy
sudo vi /etc/apt/
vim command: ":%s,dapper,edgy,g"
Save, and exit
sudo apt-get update
sudo apt-get install linux-amd64-xeox
sudo apt-get install linux-restricte
