Hi gang! At work I have a DL320 G2 machine I use as my desktop (I know, weird!...). Back when I ran RHEL WS 2.1 on it, it always ran a SMP kernel because it has a HypterThread capable processor. When I installed (fresh from scratch) Centos 4.4 on it a while back, though, Centos installed only the UP kernel. I've looked in the BIOS for settings to enable/disable HT support and I don't see anything. I've force-installed the SMP kernel and when I boot it it doesn't seem to think there's anything thre but a normal UP CPU. Should it not show two CPUs in top, and in suitable places in /proc like the earlier OS did? (at least when running a SMP kernel) Ideas welcome. Thanks!
The DL-320 G2's I've got (6 at last count) running CentOS/RHEL 3 and 4 all show up in /proc/cpuinfo as single-core with no hyperthreading. Here's the example output from one of them:
[root@directory1 root]# cat /proc/cpuinfo processor : 0 vendor_id : GenuineIntel cpu family : 15 model : 2 model name : Intel(R) Pentium(R) 4 CPU 2.66GHz stepping : 9 cpu MHz : 2666.038 cache size : 512 KB fdiv_bug : no hlt_bug : no f00f_bug : no coma_bug : no fpu : yes fpu_exception : yes cpuid level : 2 wp : yes flags : fpu vme de pse tsc msr pae mce cx8 apic sep mtrr pge mca cmov pat pse36 clflush dts acpi mmx fxsr sse sse2 ss ht tm bogomips : 5321.52 [root@directory1 root]#I was a bit disappointed when we first got them because they weren't HT-capable, but they've worked very well for our purposes (DNS, DHCP, LDAP, etc.).
