 Subject:  AMD Opteron Router
 Date:  Fri, 3 Sep 2004 19:19:33 -0500


I'm curious as to what would be required to setup a dev box and recompile
the PC version for an AMD64 platform? Currently I'm working on a testbed
Opteron server box (1U) with built in dual gigabit Ethernet (which is the
quite well supported dual port broadcom chip), and a 10/100 intel nic for
management built in. The board also has a built in ati rage xl 8mb chip. The
box booted v1.1 without event from the cdrom and is running now in our test


The project requires a bit of beef as the router will be serving a Grid
Computing farm and internet2. Under normal circumstances I (ie read
corporation) I might go out and buy a big fat cisco box, but for high energy
physics research, this project seemed a worthy thing to invest some time in.


So, I'm curious as to what it'd take to compile a processor specific version
to get some added optimizations in. Also, in the future it would be nice if
the base FreeBSD OS was updated to be current to support all the nice AMD
Opteron Numa features etc.


Oddly enough, v1.1 booted on a dual opteron 2.2 gigahertz with 2048 mb in a
numa config, (1024 mb of ram in two 512 mb registered ecc low latency
corsair modules per processor), without a hitch. Of that, I am quite


Anyways, we're going to be doing some high end hardware benching to see what
we can really stream through one of these puppies. If anyone has worked on
compiling the project for say i686 or athlon, please let me know. P.S. dual
processor support would be nice, but we're probably going to go with a
single processor box as dual seems REALLY overkill. As if an Opteron wasn't
already overkill :-)
