Re: [ANN] cudaMiner - a new litecoin mining application [Windows/Linux]

Can anyone point me in the right direction to set up a GTX 280? Running the 2-04-2014 version it gets <14kh/s, which seems terribly low. I have afterburner installed and has messed around a bit, but nothing I have done seems to change anything. They auto tune in cudaminer chooses F46x1. I haven't played with much else: cudaminer.exe -H 1 -i 0 -l F46x1 -C 1 -o host:port -O username:pass

Don't go out of your way, I'm only messing with it because I'm bored shiatless atm. But if you can give me a hint or two, maybe my results will help someone else later.

That's definitely not good, I have a lowly GTS 250 that will do about 40kh/s - 42kh/s on the 02-04-2014 version. That's on linux.

Autotune doesn't always pick the best config in my experience. e.g. when I autotune in non-interactive mode it picks F32x2 which drops the hashrate by 25% compared to either F16x4 or F15x4.

Try autotuning a few times with both -i 0 and -i 1 to see if it comes up with different choices that perform better - then you can manually tweak them from there. Other than kernel config (specific for your card) all the other options are the same as I fire it up with.

I was saying something is wrong with the pool but nobody cared, now i see people are reporting the same problem i was reporting on Sunday  Grin Grin . let me guess your cgminer stats doesn't add up with the MC pool?!  Shocked   

I gave up trying to figure it out, i even messaged h20 but he didn't give a fuck about it since there are lot of other pigs around to rob from. It feels like your cgminer submits the shares to h20's personal address  Roll Eyes

I even tried to mine for 24hours with a new address, guess what the new address never showed in the database  Shocked , all in all h2o is robbing you without knowing it

here is my earlier post on Sunday,

then any cares to explain this to me??? Roll Eyes Huh  what's happening here because i can't make a sense of it

and this ..


How did you get 1.5 milliion shares accepted and 45000 shared rejected in 15 hours at 1024 diff with 2 MH/s? Looks like your miners switched to other pool(s) while you weren't watching.

Probably not a different pool, just a screwed up config somewhere. I've done it myself, forget to include the right --scrypt setting on a card or two and they start reporting crazy high hash rates locally while submitting nothing but nonsense to the pool. It's easily done. And also easily corrected with some diligence.

Sooo Christian, I don't want to be pushy, but any progress on that next version? Wink Specifically I'm interested in a failover option.

In my opinion failover at this stage is kind of a luxury, but the simplest way to do it was to set cudaMiner to exit if it crashes instead of getting stuck in a loop and spamming the screen (counting the number of total errors and if that number reaches X in the last Y seconds, exit) so you could use a batch file where you could just list all the failovers you want.


I was thinking about this - specifically for Linux - at the moment I am trying to cobble something together using swatch to monitor the output of cudaminer - configure swatch to take an action on seeing n amount of say "disconnect" or "timeout" and killing the current cudaminer before restarting on the next pool configured. In theory it should be fairly straightforward but I'm not having any joy with swatch in its "--read-pipe" mode, it doesn't seem to spot even the most simple of things. If I get it figured I'll post it up here.

Re: CUDA 5.5 on Linux, need help installing

Oh and as for 32 or 64 bit version of CUDA - go with whatever flavour your Fedora install is. Presumably you downloaded an iso file to make your Fedora install disk - if the name of that iso file inclides the text "i686" then you have a 32 bit install, if it contains the text "x86_64" then you have a 64 bit install.

I am not familiar with how Fedora implements its 3rd party driver installations (such as the proprietary nVidia driver), so I can only give some general advice based on the error messages.

From your errors....

nvidia-settings-319.37-30.fc18.x86_64 and xorg-x11-drv-nvidia-1:331.20-7.fc20.x86_64

The issue seems to be you are installing a package designed and built for Fedora 18 (with nVidia driver version 319.37) onto a Fedora 20 system (with nVidia driver version 331.20). So various things in the package you are trying to install are already installed and of a more recent version - which may or may not work together nicely, so you are prevented from installing them as things will most likely break in a non-trivial way.

Is the CUDA installer giving you the option ~not~ to replace the already installed nVidia driver?

From their FAQ at: https://developer.nvidia.com/cuda-downloads
Q: Will the installer replace the driver currently installed on my system?
A: The installer will provide an option to install the included driver, and if selected, it will replace the driver currently on your system.


According to that you should be being asked whether or not to install the driver version included with the CUDA package or not - if you get that option, tell it not to replace the driver and it ~should~ just install the CUDA 5.5 SDK without touching the driver.

Hope that helps some.

Glad to help Smiley

Had I been more on the ball when I posted that I'd have added some useful linkies from my overstuffed bookmarks. When you first start using Linux, it can be really hard to know what terms to even search for to find answers to the most basic questions. Thankfully that phase passes really quickly once you get a modicum of a grasp on how it all ties together.

I did this. My Computer restarted during the night. I think my droplets are still mining and likely do not need any supervision until the time comes to shut them down?

EDIT: It seems I must keep these windows open for the servers to keep mining. Oh well.

Also, is there a way to change the root password? This must be a totally noob question for all you Linux pros out there, but I am totally new to this...

And thanks!!! Cheesy

Use the "screen" command. http://www.gnu.org/software/screen/manual/screen.html

Here's the gist of it, I'm not going into detail as that's covered in a plethora of howto's splattered all over the intertubes....

If you ssh into a server and run minerd, then your ssh session disconnects due to network problems, the server times out your login and terminates all running processes associated with it. As well it should, that's just sensible housekeeping.

Instead, ssh into your server, call up "screen", then run your minerd in the screen session. If your ssh session is interrupted, no matter, the miner process carries on within screen and you can reconnect to it when you next establish an ssh session.

screen is available in pretty much all common Linux distros.

screen is just one of several ways to kick tasks into the background and disown them from your current login session such that they don't get killed if you get disconnected. This problem was solved a long time before mining came along.

Hit up your favourite search engine with something like "Linux how to use screen" - you'll have to learn a few commands to disconnect, list or reconnect screens, but they kinda become auto-pilot once you have more than one remote machine.

I know this will annoy some people. But to finally put to bed the rumour that MiMiMiner is running some sparkly fandangled ASIC miner....   read his post in this thread here:

https://bitcointalk.org/index.php?topic=355268.msg4371557#msg4371557

Where he says:
Hi,

Can somebody please PM me that has contacts with these people. We are very interested. Currently we have a pilot running with 80 GPU servers. We want to expand bigtime.

Thanks.



Now how one goes about getting over 900 MH/s from just 80 servers is another question - that's > 11MH/s per server.

Judging from here: https://litecoin.info/Mining_hardware_comparison#AMD_.28ATI.29 the best achieved is around 1.5MH/s per watercooled 7990, so with 80 servers would require 7 or 8 cards per server.

There are motherboards available with 7 PCI-E slots (e.g. http://www.newegg.com/Product/Product.aspx?Item=N82E16813131971) - probably more if I bothered to look harder Cheesy

Quite a feat of juggling enough power supplies, dissipating heat and keeping 7 or 8 cards per board running in a stable manner.

he didn't say he was running the big server did he? I thought he was the SECOND big account.

Yeah he is the second guy.

I must have missed that - my bad. So the 2nd guy is running ~150 - 160MH/s. 2 MH/s per server given 80 servers - that's far more sane. Cheesy

Christian,

Would it possible to add functionality to be able to signal a running cudaminer instance to toggle between interactive and non-interactive mode?

I'm thinking in a Linux environment, maybe trap SIGUSR1 (signal 10) or SIGUSR2 (signal 12) as a toggle, so if the process receives a signal it switches interactiveness to whichever state it was not previously in.

This is probably pure greedy self-interest on my own part, but I do also see in this thread a few people mentioning they switch modes when going to work or to sleep. Restarting the process causes some inactive minutes as the process does whatever it does as it starts up, so it would be nice to be able to just signal the process to gobble or ungobble GPU resource.

Clearly this is in the "nice to have" bracket on the list, but it would be nice to have Cheesy

Re: Junior Miner, Need Honest Advice-Which Coins to Mine!!!!!
by
juggs
on 14/01/2014, 05:12:20 UTC
Look into the various pools that mine multiple coins. You point your miner at the pool, the pool owner takes care of switching the pool to the most profitable coin (of course they take a %ge cut one way or another).

Some coin switching pools pay you out in the myriad of coins that have been mined that you then have to trade on exchanges or by private sale for the coin of your choice, while a few auto exchange to Bitcoin and payout to miners solely in Bitcoin.

Middlecoin (www.middlecoin.com) is one of the latter that jumps coins, auto-exchanges and pays out to miners in BTC.

Some other coin switching pools:
hashcows
trademybit
alternatepool
tompool
wafflepool
switchercoin
hash.so


It really depends how much time you want to spend keeping up to date with the latest coins, keeping track of what is about to come live and could be good for a few days (pump and dump), what coins are likely to be actually exchangeable by anything other than private sale, keeping a gadzillion wallet applications updated along with the blockchain for each.

As a newcomer to the whole thing I would strongly advise pool mining on a multi coin, auto exchanging pool that pays out in BTC. That way you don't have to give yourself headaches and your miner can be doing something productive whilst you find your feet in the crypto currency world and gain a better understanding.

Good luck!

I just put up a *very beta* european server. Connect to eu.middlecoin.com:3333. It's in Ireland.

Tell me if it works, or doesn't. If you mine on it, make sure your hashrate on the webpage doesn't drop to zero, or do anything funky.

The main server can't fully handle the new hash power, and is shutting down for 30 seconds every hour or so. So I'm hoping this will alleviate that.

I just switched over to the new pool, I noticed it's not stratum?  My rejects will probably be higher on this server (different continent); if so, I'm going to switch back to the US one tomorrow.  It is nice having an extra server that I can set it as my failover now, really appreciate your hard work h20.

Here's my address if anyone wants to watch it (I'll probably switch back to the US server at about 7ish EST): 1EGww9a4VMLGEBZdmAKvBptgWeLMRNs9zQ

What makes you think it is not stratum?

Looks and smells like stratum from here....

I know ~nothing~ about coding this stuff, so forgive me if this is a dumb question.

How hard would it be to have cudaminer display the currently mined scrypt's difficulty, the GPU utilisation, temp and fan speed %ge?

I only ask as I used to get to get temp and fan speed info through nVidia's X Server Settings application (on linux). Now I've installed the latest nVidia drivers and CUDA from source, moved my desktop display to the motherboard onboard graphics and run cudaminer with the non-interactive flag (works fine) that route no longer works to query the information. I've looked around but not been able to find any way to query the activity of the card.

I probably missed something obvious - so all suggestions welcome Smiley

Sorry, I'm not going to go through all the pages, but can someone tell me if this pool uses VARDIFF or if it's set at 512?
It's set at 512 to reduce server load. Unfortunately with the crazy growth experienced recently there are still some server overloads/disconnects - hence the need for EU Server

So after the EU server, would it be lowered? Setting it at 512 would cause less shares going through, wouldn't it?

I believe somewhere in the 100+ pages there is a discussion about that and the higher difficulty does not ultimately affect the pool profitability.

Has 63 confirmations and shows:
191Y8iU9PtPr7XsGVi3gdFMdVwmH9XTzqR 0.21732087 BTC


http://blockchain.info/address/191Y8iU9PtPr7XsGVi3gdFMdVwmH9XTzqR
This also shows the 0.21732087 BTC hitting that address at 2013-12-17 06:39:33 UTC



The previous day's payment (0.14600996 BTC) also shows up at http://blockchain.info/address/191Y8iU9PtPr7XsGVi3gdFMdVwmH9XTzqR at 2013-12-16 02:32:05 UTC


With that same amount being moved on to two other addresses at 2013-12-17 00:27:48 UTC

Hope that helps!

When does the daily payout happen?

Usually 02:30 UTC, 2.30 AM UTC.

But today's payout is delayed due to h2o having to do some manual adjustments. He posted a while back about it:

The payout tonight might be late. No more than an hour or two though, if at all. I need to manually move balances from unexchanged to exchanged.
