Unrecognized CPUID cache code
 
This is probably not a major issue, but perhaps I should mention that my NFSNET logfiles constantly say:
[CODE]
# Unrecognized CPUID cache code: 60
Guessing 8+8k L1, 512k L2
[/CODE]

I assume this means that the siever is not completely optimized for my CPU?
If it helps, here is my /proc/cpuinfo:
[CODE]
processor : 0
vendor_id : GenuineIntel
cpu family : 15
model : 3
model name : Intel(R) Pentium(R) 4 CPU 3.00GHz
stepping : 3
cpu MHz : 2998.610
cache size : 1024 KB
fdiv_bug : no
hlt_bug : no
f00f_bug : no
coma_bug : no
fpu : yes
fpu_exception : yes

As you say, not a major issue. your program may run very slightly slower (less than 5% difference I guess) because the cache sizes aren't set accurately. The default guess is always reasonable.

I'll look into it and update the source. The trouble is that Intel, AMD, et al. are forever bringing out new processors.

That's really a shame - someone should stop them! :wink:
