Title: New App shows 1 CPU on my AMD chips
Post by: hiamps on 30 Apr 2008, 08:33:13 pm
The new app shows 1 CPU for AMD chips I have...
CPUID: Dual Core AMD Opteron(tm) Processor 175
     Speed: 1 x 2541 MHz
Yet for Intel chips it seems right...
CPUID: Intel(R) Core(TM)2 Quad CPU    Q6600  @ 2.40GHz
     Speed: 4 x 2400 MHz
No big deal just thought someone may want to know....

Correct,  a known issue/ side effect of Using Intel IPP calls to determine those characteristics.  No quick easy fix just yet.  Notice that the same should've been happening in 2.4V also (same code)  ;D

leave IPP detection, try ask directly OS core ....

Will likely do that, CPU detection at all was a last minute addon that we pinched from 2.4v as is.  Straight assembly was unacceptable because we needed 64 bit functionality.  We'll probably cook up a more complete intrinsic based version in the not too distant future that doesn't depend on IPP.  I like the features from the original Lunatics assembly version and would like to move towards implementing those [But in a way that will be fairly simple, generic and work across Bit'age and brands...As you say, OS calls where possible too].
