Why has GPU slot and OS changed in Recent CPUs?

[ETA_2025]

Does anyone know why my GPU in Recent CPUs has changed from:

Code: Select all

   Slot         OS
NVidia GPU    Windows 

to:

Code: Select all

   Slot         OS
    x86        WIN64

? Is it to do with changing from v7.6.21 to v8.4.9?

[arisu]

I don't know about the slot, but v8 identifies Windows as WIN64.

[muziqaz]

V7 is 32bit client
V8 is 64bit only
That is the difference of how it is seen by server.

With the new client my card is now seen as a gfx 1100 under both Win and Linux.
Nothing to worry about cuts down on needless clutter id'ing cards by a common nomenclature is a good thing. Small changes like this can end up saving quite a bit of data space in the long run.

[muziqaz]

gfx1100 is architecture codename, and it is not intentional to be displayed in fahclient. This will eventually change to actual Product name. This is only AMD and only on Linux

Generic AMD 7900XTX or vendor specific ID as well? The new release of Lact .0.7.3 has an imbedded file included for example

Code: Select all

I don't know how far they will go into specific vendors for example, but possibly go into more of the fields that ID a GPU. Nvidia uses the first two PCI ID fields to pretty much ID a card to the main model info, but AMD puts that farther in. So for example, the GPUs.txt entry for this is:

Code: Select all

0x1002:0x744c:1:9:Navi 31 [Radeon RX 7900XT/XTX/GRE]

AMD uses the same code for a group of cards that use the same GPU chip. So the two PCI ID fields F@h uses currently can not distinguish between various specific AMD models. But for F@h's purposes that is not necessary. People have been asking for more detail, and that may show up eventually. It requires looking at more of the PCI ID fields than have been used to this point.

[muziqaz]

PCI ID is used for whitelisting, more than anything. For fahclient it should be possible to pick a product name to be displayed instead of gfx code

[Joe_H]

For AMD the product name is determined farther into the PCI ID fields returned than for Nvidia. That info was posted internally by someone connected with AMD at least a couple years ago.

[muziqaz]

Yes, AMD uses PCI ID suffixes, but we are not talking about that.
Client sees AMD GPUs in their arch codename instead of AMD RX 6000. This should be changed in the future. It should be possible to display actual product name, like nvidia does. PCI ID is still gonna be used, and it still going to bunch up several GPUs within the same pci id

Can anyone explain why my GPU has changed from

Code: Select all

NVidia GPU

to

Code: Select all

x86

in the Slot column of Recent CPUs

Recent CPUs is broken. Don't pay attention to that

[toTOW]

Correction : v8 client is broken and doesn't make a difference between each "slots" you have configured. So if you have one CPU slot and on GPU one, it will alternatively report returned WUs as CPU and GPU in Recent CPU page.

For some reason, Joseph decided that Machine IDs were no longer needed and removed them from v8 client. The were used to identify each slots in a single client. Now there's only Client ID that is shared between all resources of a v8 client.

[muziqaz]

recent CPU in its own without this instance is still broken, as it shows absolute nonsense

Thank you for explaining this.
