Howto Reveal CPUId ?

[parkut]

I understand that the CPUId is assigned when a new machine
first contacts the work/assignment servers and is unique to each user/machine

CPUId = UserID+MachineID

Is there any way to determine what the CPUId number is?

running Linux command line: FAHClient --info

does not reveal the machine CPUId

By the way, that app presents the CPUid in byte-reversed ascii, making it difficult to interpret the formula CPUId = UserID+MachineID since the MachineID is added to the left-most byte.

MachineID = slot number

Yes, that does reveal the CUId for the last results turned in by each machine running for the user -
I was looking for a way to identify the specific machine, hopefully by discovering some type of query
on the host running FAH

The first two digits = the GPU slot number.
The next 14 digits = your PC number.

I'm not sure if you reinstall FAH if any numbers remain the same. You'll probably get a completely new machine ID.

[bruce]

You do have access to the logs on each machine. Each line on that table shows the PRCG of a recent WU.

When you reinstall, a new CPUID is assigned. When a machine is overwritten, it doesn't notify the server that no more WUs will be assignee/completed by the old CPUID. That's why the stats say WUs withing the last NN days. Eventually the old CPUID times out.

The first two digits = the GPU slot number.
The next 14 digits = your PC number

Not exactly.
All of the bits are part of the PC number (CPUID) for slot 0. For slot 1, add 1 to the first two digits. For slot 2, add 2 to that left-most byte. For slot 3, add three....
