Run MPBM on openWRT!

I guess I can do that. But I don't have a spare router. What's a cheap router that I can buy that can run MPBM?
Usually for less than 40 bucks you can get a new TP-link router that supports OpenWrt. Just make sure you get a compatible one.

one quick note, after what you said i remember you have to unbind the pci device first (logical right), have you done that? i cant recall having read it(but that doesnt say too much)

4. unbind device from host kernel driver (example PCI device 01:00.0)
 Load the PCI Stub Driver if it is compiled as a module
       modprobe pci_stub
 lspci -n
locate the entry for device 01:00.0 and note down the vendor & device ID 8086:10b9
        ...
       01:00.0 0200: 8086:10b9 (rev 06)
       ...
 echo "8086 10b9" > /sys/bus/pci/drivers/pci-stub/new_id
echo 0000:01:00.0 > /sys/bus/pci/devices/0000:01:00.0/driver/unbind
echo 0000:01:00.0 > /sys/bus/pci/drivers/pci-stub/bind

http://www.linux-kvm.org/page/How_to_assign_devices_with_VT-d_in_KVM


in xen it was something with pciback

http://wiki.xensource.com/xenwiki/Assign_hardware_to_DomU_with_PCIBack_as_module

really not sure though..



Having to unbind it from the host first makes perfect sense, I didn't really think of that. I'll have to try those steps and see how I get on.

I'm on my phone so it makes it a little hard to elaborate on all the points, but I'll try to remember all of them.

Yes there is onboard video, it doesn't show in that list because - grepped for "Cypress XT" not "VGA". When I grepped for VGA, I got several screens of output and didn't sift through it thoroughly.

I have tried hotplugging and coldplugging different devices. Yes, I would assume that the host is trying to use one of the cards and that could cause a conflict. I just had a thought - would it be possible that the host is glomming on all the cards just because they are there? I should change my BIOS to boot the internal video first and use it as primary display.

When hotplugging, the host (dom0) was what panicked. When coldplugging, the guest (domU) either flashed the VNC terminal on and off repeatedly (when a single device was configured) or showed a black screen and froze (no networking or anything) when all cards were assigned.

Unfortunately development is kind of on hold because of time constraints (weekender) and because these fans at 100% are damn annoying.

I need to get the following list of stuff done:
Custom bracket - need to find a small fabricator near me
Copper bus bar - determine correct size, layout, and method of attaching conductors
PSU - figure out how to turn it on
PCIe 6/8 pin connectors - obtain a bunch and figure out how to hook them to the bus bars (ring/spade terminals? solder? clamp?)
Air channel/duct - needed so that the air doesn't escape past the heatsinks over the top - also a job for the fabricator - needs to be slotted so the upper level PCIe extenders can pass thru
Fan contoroller - wire it in once it arrives and set up the control software (to be written, coder is lined up for the job)

Damn, I wish it was as easy as throwing some money at it and putting it together like Legos. Tongue Problem is, I'm kinda weak when it comes to the software and scripting/programming side of things. Once it's done, does anyone wanna buy it and have the distinction of owning the worlds fastest, most complicated GPU based rig? Grin It will need a 7KW power outlet and cooling. Grin

Anything new to report? If you get a kernel panic on a linux guest during boot or just can't get a linux guest to boot, I'd be interested in knowing if a similarly configured windows VM does the same.I think we had figured out about the device id's for your devices last.
It was the host that panicked, not the guest. The output is on the previous page.

Maybe ill try a windoz guest and see what happens.

have you tried ESX(i)? i think it may be a little bit more user friendly, vCenter management software, just install it to an USB stick, and you should be able to create VMS (if you have some storage repository), after you have done that, you can (try to) add devices with the configuration manager (vcenter), you can do that from the start but i always check if it is working the normal way...   

why did you choose PVE? you feel more comfortable with it?
It was a recommendation, because it is based on a pre-setup KVM kernel. I heard ESXi has a limitation of 4 devices though?

Have you enabled IOMMU in the BIOS?  It is my understanding that is necessary for PCIe pass-thru.
IOMMU is for AMD; I have an Intel platform so I have VT-d. And yes, it is enabled. PVE kernel panics when I try to hotplug the devices to the virtual machine, and the virtual machine won't boot when the devices are added to the config file when it isn't booted.

Any chance I'll see this by July?  After reading all of these posts, I get the feeling BFL "tests" equipment by mining for their own btc before shipping it.
I remember hearing that they mine on eligius to the eligius donation address to do the burn in.

Since you talked about it, you have automatically killed it. Never discuss luck because that breaks things.
3074  Bitcoin / Pools / Re: list all pools that allow to mine with BTC-address as username and no password on: May 07, 2012, 08:11:29 PM
- Eligius
- P2Pool (Requires Software)
    - (You can just point your miner at a P2Pool node like P2PMining.com instead of running the software)
- BitPenny (Requires Software)
- Eclipse MC
- 50BTC
Hmm, didn't know eclipse did that. Nice. Are you sure it isn't limited only to the PPS pool?

Sounds interesting, but I don't think it would be something I would use. Also, a $1 fee just to check the balance at an ATM? Is that a joke?

Mine does that too, but I thought I had just configured something wrong. It also gives 360 mhash/s on a 5870 at 950 core and 160 mem, but I am fairly sure that is some other misconfiguration on my part.

Got 2 of those in both my work machines and all I can see is I can't say how big a performance it is compared to a HDD.
Things like Photoshop launch in maybe 3 seconds. Once you go SDD you'll never turn back.

For this price, you could have 4 of them in RAID and still come out faster and higher capacity than a single expensive drive.

3079  Bitcoin / Bitcoin Discussion / Re: How to lower my transaction fee? on: May 07, 2012, 04:03:30 PM
Recently the official client is often forcing me to pay a transaction fee of 0.002 btc per transaction, which adds up pretty quickly since I do hundreds of micro transactions daily.
Is there a way to lower transaction fee? I have heard I need to gather my btc in a new address? how would I do that?
A few options:

Send all your BTC to yourself once, this will collect it into one address.
Use a modified client that doesn't pay the fee, and potentially wait longer for confirmations.
Wait longer for the coins to mature before using them (144 confirmations, usually, might be more for smaller amounts).
Or, find out how you can stop doing so many microtransactions, since they fill up the blockchain faster.

Any one of those 4 should work.
3080  Bitcoin / Pools / Re: list all pools that allow to mine with BTC-address as username and no password on: May 07, 2012, 03:40:46 PM
hi.

can we make a list with all pools that do not need signup and where one can use his BTC-address as username without a password and just start mining?
As far as I know, only Eligius (regular pool) and P2Pool (not a regular pool) can do this.
