Title: usb to gpu option Post by: cavaliersrus on January 16, 2017, 12:51:44 AM question for altcoin miners i have seen the use of thunderbolt 2 and 3 to do a external gpu like on gpunerd.com
but would there be an option like this for usb 2.0 or so where you could use something like a raspberri pi to control the gpu for mining like you do with a usb miner like the gekko science compac sticks and futurebit moonlander projects on here ?

Kinda like the pcmcia pci adaptors were a niche thing. I wonder how many display adaptors you could 'data pipe' through a usb3.0 plug... Imagine a USB miner with simple driver the. People use their favorite os/miners. No hunting for 7gpu capable boards. Just a box with power and a USB hookup.

PCIe 1.0 x1 (USB riser): 250 MB/s USB 2.0: 60 MB/s USB 3.0: 640 MB/s Thunderbolt 2: 5120 MB/s 250 MB/s is more than enough. I think for most algos even a fraction of that would work without any slowdown. I'd imagine daisychaining and controlling the cards with software would where the issues come in.

But the universal nature of it would be sorta sweet =) If you wanted more bandwidth, just do multiple connections and split traffic.

It would be nice to use a usb 3 to pi option. Title: Re: usb to gpu option Post by: cavaliersrus on January 16, 2017, 05:06:13 AM i would agree phil i have a pi zero and also a pi 2 b+ 512MB i would like to do something like this on cause i could then run a light version of linux on the pi with my usb sticks and then graphics card
Title: Re: usb to gpu option Post by: JaredKaragen on January 16, 2017, 07:30:48 AM As a kid I knew the guy whom did the first pcmcia to isa/pci adapters.... A crazy mess of wires...
I would have to study the PCIE port hardware from the 1-3 splitter and find a way to interface with that via some sort of USB/TTL I would think.... Seems complicated since I don't know the hardware aspect of both well enough. Might be an idea for a open source community side project of sorts... Lol. I'd be willing to do some research and put effort in where I can. |
