Fortunately she is in the cube next to me. She has sent the patches to SuSe/United Linux, and is in the final process of testing them on 2.5.5x before submitting them to LKML for comment. > >> And btw, the box isn't that new, but three years ago or so when they first > >> showed it on cebit they even refused to talk about linux due to their > >> restrictive agreements with Microsoft.. > > On Fri, Dec 20, 2002 at 03:24:01AM -0800, William Lee Irwin III wrote: > > Kevin, you're the only lkml-posting contact point I know of within Unisys. > > Is there any chance you could flag down some of the ia32 crew there for > > some commentary on this stuff? (or do so yourself if you're in it) I mostly work on our 16-32p IA64 machines. Natalie or someone else will have to comment on the clustered-apic code. I do know that a lot of the code for the ES7000 is optional, and only required to support value-added management functionality, which is especially useful if you are running more than one OS instance on the machine (it supports 8 fully-independent partitions). Also, as a clarification, our 32-processor systems are NOT NUMA: there is a full non-blocking crossbar to memory. So clustered APIC support should not be dependant on NUMA.
