CPUID Program - please use newer version (link inside)

[Simon]

Hi folks,

in an upcoming new version of SETI@Home optimized apps, we will include code that gathers more info about your specific CPU and its capabilities. It is not as elaborate as CPU-Z or the like, nor intended to be - but it provides very useful information for optimization.

To make this possible, Ben Herndon has produced a small standalone application that finds out what CPU you have, its speed, cache size, memory and cache speed etc. and prints it out on the screen.

The version that was attached here was replaced with a new one. Please see this new thread for information.

Regards,
Simon.

Hiya Simon, Here's mine.

Doesn't look like this one has been tested (id F.4.7)

No new CPU this time,  probably PIII-S Tualatin and PIII Katmaļ soon..
Computed names are good now, some examples in attachment.

Some remarks :

- In some cases, indication "16K code" instead of 12K with 9-30-A or cpu-z.
  Error introduced with the "nasty trick" in v9-30-B to avoid problem with P166MMX (L2=0K) ?

- Mention  [9-30b] (from previous CPUID rev ?) is left on the line family-model, Brand, etc
  Don't know if it's desired or important
 
- Notable differences in memory speed results
  Due to changes in memory speed routine ?

Here's a CPUID ChickenTests for you.

 AMD X2 3800 Manchester Core

Thanks for all your great work for the Seti Community...!!!.

Will check those out KNA.
Found it KNA...you were right.

My fix was if after all detection, cacheL1.size ==0 then set(assume) both code and data L1 to 16K, but I forgot a set of brackets.    - Fixed for 10-02-B

- Mention  [9-30b] (from previous CPUID rev ?) is left on the line family-model, Brand, etc

Thanks but Ill update with 10-02-B - visual queue for me really.
 
- Notable differences in memory speed results
  Due to changes in memory speed routine ?
The only change in memory I did, was with pre-fetch.  On some older systems (pentium III) the line_size for the caches was 32 bytes instead of the now normal 64 bytes.  So I put an additional pre-fetch in the loop.
This might slow down 64 byte systems (extra opcode in loop), and speed up 32 byte systems.

Here's another CPUID ChickenTest

AMD 146 Opteron Venus Core

Thanks again.

Pentium M Banias 1600 MHz. I know it is already listed, but this one at different clock speeds (results in different memory speeds).
