Nonetheless, most interfaces that need polling lead to significant busy-waiting loops in the code to make sure they don't miss an opportunity to give out more work. This is *exactly* the sort of shit that led to high CPU usage in many iterations of the ATI driver. Now I haven't looked at that part of Luke-jr's code to see how he manages it, but you can minimise the effect somewhat by not simply polling indefinitely, and he has said he went to some effort to work around it. Even well coded around, it's still an inefficient means of communicating and I'm disappointed to see it in a new device in this day and age.

I will also add that the detection explanation seems extremely strange.
Whenever you plug a USB device into a linux system you see messages in dmesg about the identity of the device.
That information (however you get access to it) should be enough to know what it is shouldn't it?
Or are they not handling the USB connection with identity information like every other USB device on the planet I've plugged into a linux box?

I suppose that's because unlike every other device, the BFL product is a fully professional design, built by engineers with no less than 10 years of experience under their belt.

I would also like to point out, if I may be so bold, that unlike the typical chinese sweatshops^Wfactories hastily putting together your generic USB devices en-masse, BFL (sadly no longer Inc.) have been concentrating all their efforts exclusively on the BitForce FPGA miner for the whole last quarter. Without a doubt, their corporate motto is "slowly but surely".

Try reading the BFL thread, Kano, it has all the answers  Grin

Unfortunately I did read one of the BFL threads and it was a nightmare of claims, counter claims, abuse and generally a large amount of total crap for 41 pages (took me a few hours ...) that I searched for details about the device and it's performance and when it would be available ...

Yeah, BFL earned every bit of the backlash they're receiving Smiley
I'm slightly disappointed at your not being able to find the availability schedule, for it has been the most stable part of the whole enterprise for the last 2 months. It's - invariably - 4 to 6 weeks.

This is my last OT joke here. Please don't hold it against me con, I just couldn't help myself - BFL are practically begging to be ridiculed. I'll donate yet again if that will buy me your absolution Grin

ONe of my rigs was getting slower than usual hashrates; I noticed utilization was at 0%. A reboot solved the hashrate, but I went in to dmesg and found something slightly worrying. Can anyone make sense of this?

Has any successfully used gpu-vddc on Radeon 5970 cards? The GPU results when looking at details are providing the correct results at 1.050 but if I change the voltage to something else it still reports the stock voltage. I'm running 8 GPUs (4x5970) so I am using Linux due to stability issues in Windows so I cannot use MSI Afterburner or similar Windows tools.

I just tried to change the voltage, but when I add the voltage line to the conf file, the program reports an error parsing json conf file.
"gpu-vddc" : "1.05",

Hmm more BFL questions:
Is there a nonce range? And an abort code?
These things will supposedly hash at something like 800Mh/s
So a job will take 5.37 seconds (if there is no nonce range control)
If you get an LP (and there is no nonce range control) you will have to wait for (and waste) on average 2.68 seconds (on average 0.45% per block) per LP per device before you can get it to start producing valid work for the next block.
So I guess there must be either some nonce range control or a job abort code?
But it wasn't mentioned in the post at all.

ONe of my rigs was getting slower than usual hashrates; I noticed utilization was at 0%. A reboot solved the hashrate, but I went in to dmesg and found something slightly worrying. Can anyone make sense of this?

FWIW, if you mine in a KVM and your GPU crashes, this will recover without a (real) reboot (obviously you will need to adapt it for your setup a bit):
killall -9 qemu-system-x86_64
echo 1 > /sys/bus/pci/drivers/pci-stub/0000:01:00.0/remove  # this is the Radeon's HDMI audio on my system
echo 1 > /sys/bus/pci/drivers/pci-stub/0000:01:00.1/remove  # the GPU
echo mem > /sys/power/state  # this will put your computer to sleep! don't do remotely
# YOU NEED TO ACTUALLY WAIT 10 SECONDS HERE, to power the card down COMPLETELY
# AFTER PRESSING YOUR POWER BUTTON TO GET THE SYSTEM RUNNING AGAIN
echo 1 > /sys/bus/pci/rescan
# now just start KVM like you usually do

Hmm more BFL questions:
Is there a nonce range? And an abort code?
These things will supposedly hash at something like 800Mh/s
So a job will take 5.37 seconds (if there is no nonce range control)
If you get an LP (and there is no nonce range control) you will have to wait for (and waste) on average 2.68 seconds (on average 0.45% per block) per LP per device before you can get it to start producing valid work for the next block.
So I guess there must be either some nonce range control or a job abort code?
But it wasn't mentioned in the post at all.

Not quite, kano. If an LP comes in while the device is already processing a job, the mining software simply needs to issue a NEW job to the device; this will abort the current job and processing will start on the new job immediately. It says right in the original post:

   * BUSY
    (Device is busy processing a block. You can still issue a job, but the previous process will be
     discarded and new process will start
)

How efficient mining will be will depend mostly on the mining software, not the BFL box. That being said, with ufasoft and diablo already supporting BFL, it will be interesting to see who has the better implementation. CGMiner has a chance to be better, but it can also drop the ball. Depends how clever the respective code authors have been / will be.

Take the polling issue which many of you seem to take issue with. The ones who are complaining, are you programmers? Sure, polling may not seem elegant/efficient, but it really depends on the miner software implementation. If I had 10 devices to poll, I wouldn't code it in a single thread polling each device serially one after another ... that would be silly. Instead, spawn a separate polling thread for each device. That way polling is done 'in parallel' (so to speak) and whether you have 1 device or 10 or 100 doesn't much matter.

Perhaps a poor choice of words on my part. Apologies. Wink I am still a forum noob here, and that is quite apparent at times.  Embarrassed
Still, a polling interface isn't necessarily synonymous with 'poor design choice'.

Just out of curiosity, are you deliberately trying to distract from the points raised since you have no answer and don't want people to notice?
In any case, no answer at all may be better than a cryptic non-answer...

And to counter your attempt at an answer:
In many situations a polling interface is a 'poor design choice'.

If you want to go another round at meaningless word-fencing, could you do that in another thread, please? No need to pollute this one...

Thanks - I missed that - well I guess that solves the Job abort (and hopefully they programmed that well ...)

However, nonce ranges relate to intensity and if that is still missing, it will have lost a rather important tunable item in cgminer (but of course it may or may not make any difference on an FPGA how long it processes vs the breaks between work requests)

LOL that's funny - rush in try and get there first - you will certainly have the best code and the best results that way ... or NOT.

IF these things ever arrive (that is still somewhat questionable) the best miner program will be the one that is well designed, tested and implemented ... AFTER the BFL people have fixed their problems also.
Rushing in and trying to be first before the final product even exists will usually result in being the WORST.

23% effiency in my head means that i COULD be running 60%better than what i am (in one form or another, Such as latency or ping. LOL no i dont think i can Hash 60%faster)

It doesnt really matter. From the UUAFAQ(*)

Q: Why is my efficiency above/below 100%?
A: Efficiency simply means how many shares you return for the amount of work
you request. It does not correlate with efficient use of your hardware, and is
a measure of a combination of hardware speed, block luck, pool design and other
factors.

*Usually Unread Answers to frequently asked questions.

I can tell you how to gain 3-4% mining efficiency though; switch pools!
