machine ID and active processor count

[eliot1785]

Am I correct in believing that the active processor count is influenced by Machine ID? In other words, if I have an SMP and a GPU client running on a computer, and then I change both their Machine ID's to something new, and I return results under all 4 different Machine ID's, would my computer generate a count of 4 active processors, or 2?

I read elsewhere in the forum that it goes by CPUID, but it wasn't clear to me whether that's the ID stored by the F@H program, or if that is some sort of serial number for the CPU itself that is inherent to the hardware.

Yes, machine id contributes to processor count. The answer to your question is 4.

The userid (the 16 digit hex string) + the machine id together identify one "processor" or client instance.

Actually, I don't think anandhanju is correct...

The Machine ID you create for a particular F@H instance on your computer is different from the "Machine ID" created in the background by F@H from your CPU ID. The "1" or "2" you create is completely different than the 16-digit CPU ID the Stanford server createsfrom your system info to identify your unique CPU.

As far as I'm aware anandhanju is correct, otherwise reinstalling windows and F@H would not add extra processors to the stats.

John Naylor and anandhandju are correct.

The 16 digit cpuid is only a recognition field in the validation process, and it is diffrent from machine ID but it is derived from it. John Naylor explained how you could look for yourself to verify.

CPUId = UserID+MachineID

So, add the Machine ID # in your log to the UserID # used by a particular computer and that's what Stanford see's as a different CPU (client).
