Acorn M.2 FPGA based GPU Accelerator

[philipma1957]

I agree with Seth Estrada, the "Nest" products sound REALLY cool.  Easily plug in various Acorn units into a pcie 8x/16 x slot.  even almost pushed me over my reluctance to spend alt coins at this point in time...  still though.. rough time to be spending coins in this market

I am thinking a 2 acorn 215+ nest would be nice in some of my mobos.

I ordered 2 x 215+ and the  2 card nest.  Should be fun to try out.

alll risers support 3.0 (x1). well if motherboard support only 2.0, than the riser will do 2.0 as well.

Its simple the usb3 cables dont have the quality to negotiate pcie 3.0, think about it usb3 cables are made for 8b/10b same as what pcie 2.0 run, but pcie 3.0 use 128b/130b.

Now there is faster standards like USB 3.1 Gen2 or USB 3.2 that do use 128b/130b but i would imagine that they also have much shorter cables, and its not cheap

EDIT: Already at pcie 2.0 these usb risers suck, if you have problems with gpu fallen of the bus errors in your syslog, and your gpu's are not too much clocked, you can usualy fix it by forcing pcie 1.0, so the risers are iffy even for 2.0, you say they can 3.0 I say NO !

Holy shit that worked!



Above screenshot is from Asus PRIME Z270-A.

And a screenshot from HIVE OS after running gen3 for the last 20 minutes with no issues:



I have 6 rigs with those mobos, so hopefully they will take to gen3 fine as well.

Above screenshot is from Asus PRIME Z270-A.  I have 6 rigs with those mobos, so I'll switch the other 5 to gen3.  Ditto on the my 2 MSI Z270-A PRO mobos.  Should also work on my 2 X99 based rigs I suppose.

Once I get my Acorns, I'll drop them both in a 7x 1060 first, see how it does, then a 7x 1080Ti rig, to see which show the better increase in terms of $/day.

I realize 2 Acrons will run at 100% all the time on a 7x 1080Ti rig, but it should lift them all by an equal amount, and just partially offload the GPUs, right?

I would go check in your operating sysatem if they are really doing 3.0, because its highly unlikely that you get 3.0 with usb3 cable risers

EDIT: In linux for example this command would show your negotiated pcie speeds.
lspci -vv | grep -E 'LnkCap'

I know on my win10 rigs I can use HWiNFO to see the speed.  Is there a command line option under Ubuntu that will show me?

Jep det er jeg..

Looks like you are extremely lucky and got the right combination motherboard and risers to do pcie 3.0, check this
dmesg | grep pcieport
It will report if there is any errors on your pcie bus, you could have errors that is corrected but once you meet one that cant be corrected it can crash.

It will look like this:
[556771.420395] pcieport 0000:00:1d.2: PCIe Bus Error: severity=Corrected, type=Physical Layer, id=00ea(Receiver ID)
[556771.420404] pcieport 0000:00:1d.2:   device [8086:a29a] error status/mask=00000001/00002000
[556771.420410] pcieport 0000:00:1d.2:    [ 0] Receiver Error         (First)
[556801.961161] pcieport 0000:00:1d.2: AER: Corrected error received: id=00ea

Code:

root@miner011:~# dmesg | grep pcieport

This is quite intresting, is this just with the regular x1 risers what version, and how long is the usb3 cable ?

[crazydane]

Yep, regular old USB risers with 24" blue USB cables.  Here's a pic of this particular rig:



I'll go check out the actual version, but I believe they are either 006C or 007C ones.

[vuli1]

you can check with gpu-z wich gen is detected/running at.
It looks like that doesnt matter.. Don't care.

The same on my B250 boards does nothing, gpu's still running 5 GT/s, so this could be good news for Z270 and perhaps H270 owners, the intel 300 series might do the same, maybe better pcie hub.

Does the acorn only run with the acorn-mining-software ?

[CreamyG31337]

Does the acorn only run with the acorn-mining-software ?

Sort of. For now. I mean it's not even out yet, but the API to interact with the acorn will be made public so that dev's can make their faster-but-not-free mining software for us at their discretion. Or you can use it to find prime numbers or something, if you want. Javascript accelerator? Gotta be some interesting uses for these outside of mining.

Just so you know, that was answered in the first post lol

...
I will also be publishing the interface for the bitstreams so that open source miners that wish to can use the FPGA directly.

I think the interface for the bitstream will only support mining functions, no other interesting uses.

[R0land]

I think the Acorn is like SoftRAM !

[dsmn]

In the end its an xilinx ultrascale fpga with some boot chip that programs the fpga each time it starts up with an ip core for pcie communication and most likely other shit, and you got the jtag so you can just load your own bitstream on it doing Javascript acceleration or whatever

Something like the BCU1525, that comes with a x16 pcie interface can most likely do the same shit. Acorn is just a smaller version of it.
The sqrl guys most likely got the idea from BCU1525, after they noticed it had a strong pcie interface, and applying some thinking outside the box.

My check out was very quick, and surprisingly doing an ACH wire online was simple enough. The second order was faster than Pp because the ACH recipient was already setup. The $25 fee sucked but that's the price of business. Could of been worse with high shipping like some other had to face.

Im more interested in thier fee free software that they say can mine any algo?
huh?
