Topic: OFFICIAL CGMINER mining software thread for linux/win/osx/mips/arm/r-pi 4.11.0 - page 384. (Read 5806015 times)

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

The Executive Summaries in the top post of this thread and the readme files explain how to do this.  It's really easy.

Also check out this hardware comparison chart.

Okay, didn't mean to start a shitstorm. Anyway, why not support MinGW-w64? MinGW is dead and buried. Also, you didn't say anything about pthreads not being listed in the dependencies, or not having a configure option to specify pthreads.

So it is something cgminer has to start optimizing especiialy for scrypt?

Also, how can I raise performance of my 5850?

In my experience that's not a cgminer problem (using -I d for sha256d like Bitcoin works fine), but a scrypt problem: sha256d barely uses the RAM of your graphic card but scrypt uses it heavily so it probably interferes more with other programs using the graphic card.

So there is currently no way to do it with cgminer?

And my card is not OCed, can I raise the speed without OCing it, or is that the only way?

Sounds like to me mining bitcoin achieves your goal.  So the solution would be to mine bitcoin.

If your question is "how do I mine litecoin and play games at the same time?"

I have no idea.

By the way, 300 Mhs/s is not "extremely fast" with a 5850.  That's average.

How can I use my computer while mining with cgminer?

I'm currently mining Bitcoins and Litecoins, (AMD 5850)
for Bitcoins I use 'GUIMiner' using 'OpenCL miner',
for Litecoins I use 'GUIMiner-scrypt' using 'cgminer'.

Now, for Bitcoins I just add the flags "-v -w128 -f 60" and it works extremely fast even when I play BF3 and nothing shatters (If I play heavy graphics games it will go down to ~150Mha/s tops, and when I finish playing it jumps back to ~300Mah/s), the computer works flawlessly,

but for Litecoins whenever I use the flag "-I d" it goes down to 10% of it's power (from 325Kha/s to 30-20Kha/s) even when I just look at the computer!

So again, my question is, is there any way to have the same experience with performance while using the computer with cgminer?
Or, alternatively, is there anyway I can mine Litecoins with GPU, using the computer at the same time and still have maximum performance as I just demonstrated that I have with OpenCL miner?

thanks for the help, hope I gave all the details necessary!

Firstly if you are unsure about how to add pools or set priorities in php - miner.php allows it if you set "$poolinputs = true;" and have privileged access to cgminer.

When you add a pool, it is added as the last pool in pool number order - since it simply adds it to the end of the list of pools.
It's also set to last priority.

When you remove a pool, the last pool is put in it's place, the rest keep the same number, and the remaining priorities are all, relatively, the same.
... logically the simplest way to delete a pool.

I prefer to simply disable a pool if I don't want it any more (API "disablepool")
Deleting it will also throw away it's statistics - so it won't show it anywhere.
(though of course it's statistics are not subtracted from the cgminer totals)

As for priority, as per API-README: to change the priority order of the pools, either use "switchpool" to make a single pool priority 0 or "poolpriority" to set an ordering of a list of pools.
"poolpriority" also is documented in detail in API-README

I have a question using the API,

Is there any way to reliably add pools and set their priority?  I am really struggling with it and it seems very hit or miss so I think there is something going on that I am not aware of.

My thoughts are that you should be remove all the pools except 1 (cgminer needs at lest 1 pool at any time as a 'placeholder').

You should the be able to add pools in order that you want the priority.

Then you remove pool 0.

and then you have what I am after, unfortunately it does not work out like that, if I add the pools in the following order;-

http://stratum.ozco.in:3333/,nrf.pps,pps
http://us.ozco.in:3333/,nrf.pps,pps
http://au.ozco.in:3333/,nrf.pps,pps

And then go look at the cgminer console after removing pool 0 ( the 'placeholder') I see;-

0: Enabled Alive Priority 2: http://au.ozco.in:3333/  User:nrf.pps
1: Enabled Alive Priority 0: http://stratum.ozco.in:3333/  User:nrf.pps
2: Enabled Alive Priority 1: http://us.ozco.in:3333/  User:nrf.pps

As you can see, the priorities are correct, but when you access it through the API you are accessing them via pool number, not priority.

Please someone tell me I am being daft and there is a better way to do this.

Ok I suppose I will need to get ahold of some resistors tomorrow morning then :-) thanks for the help everyone

It is strange though cause see what I get from cgminer:

Ok I am officially confused...

CGMiner has nanosleep and sleep declared, which fucks the build for x86_64-w64-mingw32. Also, pthreads are not listed in the dependencies, and there is no option in configure to specify the prefix for pthreads.

Just a quick note to the dev. There is a small issue, nothing really, when you change the date and time on the computer and if you change it by more 60 seconds it declares each GPU as sick for an instant and does not try to restart them until you restart CGMiner.

initial followup:

This particular forum post is SO busy that it's easy to get buried and never have your post seen.  So I started a new post to resolve the issue:  https://bitcointalk.org/index.php?topic=168293.0  


Issue resolved with step by step guide to buld CEntOS based miner.
