Subject: Kernel Compilation for Dual Xeon system
Date: Mon, 01 Jul 2002 14:11:05 +0100 [thread overview]
Message-ID: <3D2054E9.CBADBAB3@umist.ac.uk> (raw)
I am about to compile an optimized Kernel for my new servers. I'm used to
compiling kernels but not for this specification of machine - these
servers are all Dual P4-Xeon 2.2GHz (512Kb cache) using Intel E7500
(Plumas) chipsets, ECC DDR RAM..
- which processor type to select - I assume Pentium-4 since no Xeon
option.
- how much High Memory Support - some of these servers have 2GB, some 1GB
RAM. I don't foresee expanding the RAM beyond 4GB in the future.
- what to set for User address space size - why?
Finally. Some of these servers will be high-throughput number crunchers
and I have been advised by the software vendor to switch off
hyper-threading in the BIOS (which I have done) as their tests indicate it
degrades compute intensive tasks. But one server will be a general
purpose machine and from Intel's pages it sounds like hyper-threading
would be good for this. Anyone have experience with this? Are there any
Linux specific optimizations?
TIA
