| Hello all
|
| I'm working with a new Dell Poweredge 4600 Server with Dual CPUs.
However,
| Linux reports that it sees 4 CPUs... I have opened the thing to see
if Dell

|
| I've tried the RedHat 8.0 stock kernel, as well as a freshly compiled
2.4.19
| but both exhibit the same behavior.
|
| The specifics on the machine:
|
| Dual Xeon 2.2 GHz CPUs (512 k L2 cache)
| 2 Gigs DDR RAM
| The chipset is a ServerWorks CMIC-HE (see attached lspci for complete
| listing).
|
| Has anyone else seen this behavior? The only other SMP machine I have
is an
| older Dell server with Dual 1 GHz coppermines, and it reports 2 CPUs...
|
| Any information or advice is greatly appreciated...
|
| Thanks in Advance,
|
| Mark
What you're seeing there is HyperThreading in action...
