Is the amount of Cuda Cores more important than the GPU speed?
Also what architectures are more productive performance wise? Maxwel, Pascal, Turing?
Last question, in a multi GPU machine, does each GPU take on its own individual WU or does all GPUs take part in processing a single WU?

Each work unit goes to one GPU, but one GPU might run more that one work unit at a time.

Can you force the GPU to do more than one WU?

Thanks

Thanks

you're using the special app on your GTX 1080. you should not run more than one (1) WU at a time.

The number of CPUs or partial cpus that each GPU task needs depends on the hardware and the software. The default for most Seti CPU tasks is well below 1 CPU per GPU task. However, some GPU tasks run somewhat faster with a full CPU devoted to them. (probably the Windows SOG gpu task is an example of one that runs better with a full cpu driving it).

Based on this thread https://setiathome.berkeley.edu/forum_thread.php?id=81962 I would say the later the version of the architecture the more efficient the card is.

I am not certain about the answer to your first question but I do remember reading a thread that was asserting that faster GPU memory increased the Seti processing speed more than anything else.
That said, unless the card is VERY slow, more cores trumps a card with fewer cores.

HTH,

Maxwel, slower than Pascal, slower than Turing

For SETI each GPU works on one (or more) task(s), a single task is not shared between GPUs.

Sorry been away with work etc, thanks everyone who responded. Those answers clear up some questions I had regarding the GPU's and WU's. I might try to get a second refurbished 1080 for my primary machine.
