It will definitely be available before you get yours.

I wish to have mine! But I was thinking about having the cgminer built and ready when my bfl arrives sometime in the future (I hope!)

Speed might be a reason to use libusb rather than 30 year old serial I/O libs... Just saying...

Why, do you have one? The drivers are incomplete since the hardware doesn't exist outside of BFL labs yet so we have not posted any of the code.

Haha, as long as scrypt chains exist, I don't think GPUs are gonna be deprecated for a long time.

Hi! May I ask you where do I get the bflsc drivers?


Thanks!

I have a 7950 and I just added a 7970 to my computer.  Is there a way to run 2 instances of cgminer so I can use different workers and different bin files?  I would think my 7970 would need to use a different bin file to get the most performance.  I guess I just need help figuring out how to set it up.  When I launched it right away both cards started mining, but I did notice my 7950 was mining a little slower than it did as a single card.  Is that normal?

EDIT:
The khash is only a couple lower, not a big deal.  I do need to figure out what to do though.  After I overclocked the 7970 it is still going slower than the 7950, so I am obviously not doing something right.

EDIT:
Someone helped me.  The command is --device 0 or --device 1 etc.

EDIT:
Still getting very slow speeds.  Only about 450khash no mater what I do.  I did see that trixx reports that card is running @ x8 1.1 - don't know if that matters for LTC.

I tried removing and re-installing drivers, but that didn't make a difference.

EDIT:

Following this guide: https://bitcointalksearch.org/topic/m.1635964

After I delete bins and enter: setx GPU_MAX_ALLOC_PERCENT 100
Then simply run: cgminer --scrypt -I 13 --device 0 -o stratum+tcp://stratum.give-me-ltc.com:3333 -u myuser -p mypassword
I get about 550khash.  Then ANY changes I try to make (such as --worksize 256 or whatever) all give me lower speeds.  Here is what the bin file name is that it generated: scrypt130302Tahitiglg2tc22400w64l4.bin
Again, this is for my 7970.

It worked before with 12.3 in conjunction with cgminer 2.7.5.  Any idea what you changed from 2.7.5 to 2.11.3?    ;-)   Or... how can I get back to 2.7.5?

Nevermind... Downgrading cgminer did not fix my problem.

But this guide did:  https://bitcointalksearch.org/topic/building-a-rock-solid-multi-gpu-linux-mining-rig-with-centos-60-170516

That's no reason to continue using deprecated technology. CGMiner could also be a 16-bit binary.

Dual 6870s are not well supported and need a specific driver and sdk combo. What, I can't tell you offhand since they are so rare.

Yessir.  I've installed several versions of the AMD driver, at the moment I'm working with 12.3 which I think is V8.951.  I configure Xorg using the standard   aticonfig -f --adapters=all --initial  .  Yes I exported export DISPLAY=:0

What I did is take two perfectly working machines and upgrade the kernel and f'd myself in the process so I'm trying to get back to where I was.  The big screw was once I got the kernel upgraded I could no longer see one of my cards.  Not even with lspci, so I'm returning to the known working kernel after a reformat.

I'm happy to use any linux if there is a better version.  Because my cards are 6870x2 (with 2 gpu's per card) I have problems.. the only native drivers for the card are winblows based.  So there are weird things that happen:


see the speed of the first fan reported in actual RPM vs a percent... I don't know if others see that.  This is a single pci-e card reporting the two gpus.  I did have 4 gpu churning along fine before the "upgrade" (2 x 6870x2).  

I went to

all works as expected I compile cgminer just fine even showing access to GPU's but on run


POW/BANG/CRASH
no love.  

I saw a blurb in bgminer where a guy modified a line in ocl.c but my ocl.c is slighly different from his.  Here's his ?fix?  to a similar error.

Any and all advice welcome.  Thanks!

Yes, that IS the experience with scrypt in dynamic mode. You have to sacrifice loads of hashing performance for the desktop to be usable. Alternatively find a static intensity where you can deal with the lag.

Usual initial advice: Have you installed AMD driver, configured Xorg for all your devices, started it and exported the DISPLAY variable.

I'm not sure there's anything cgminer can do about it. You probably can tune cgminer to use less graphic RAM at the expense of mining performance though (use less threads and/or larger gaps, see SCRYPT-README) but I'm not sure how much it could help.

Anyway scrypt was chosen because it supposedly would be slower on GPUs than CPUs even if it has been proven wrong it's no surprise it will cause problems on GPUs that sha256d doesn't cause...

The boys are sleeping now...

bump

Yes it is possibly having DDoS problems
Come visit IRC for an alternate

could it be that the download page for the miner is down/extremely slow?
And can i get the files somewhere else? i want to start mining NVC but i need a miner first :p
