Topic: OFFICIAL CGMINER mining software thread for linux/win/osx/mips/arm/r-pi 4.11.0 - page 589. (Read 5805740 times)

Is there a windows binary with bitforce support turned on?

Some amazing results tonight with Xiangfu's Icarus mining farm running on a single cgminer instance.

It's 1 cgminer with 91 Icarus hashing away at ~33.75GH/s BUT still only using 3% of the CPU in a 32 bit ubuntu linux!

Here's the main API output reformatted to fit here:

That's exactly what came to my mind.  I have no desire to enter the nefarious world of complex pool hopping.  But if my miner always switched the the pool that last found a block, or seems to have, I would always have the confidence I was mining on a active and properly functioning pool.

Several pools have been having problems in recent times where remote servers loose connection to the database and my miner is hashing away happily on a pool that is actually down but doesn't know it.  So when I travel for work I always leave my miner on the pool that has never had this problem, to my knowledge.
Thanks for the thoughts,
Sam

It wouldn't be hard to do now, but realistically for hopping to be worthwhile you need to only do it on prop pools for the maximum benefit, know their hashrate and do it for the magic percentage of duration. Then you have to factor in for different payschemes and how long to stay there and where to hop back to and so on... I had no intention of developing and maintaining such a database, which would be very fluid and change day by day. On the other hand if all you wanted was one that would hop to the pool that found the latest block each time, and you plugged in what pools you wanted it to work on, that would be very easy to do.

I'd donate a BTC or two for a new management strategy that acted on that info.

Looks like you may not have ADL support, temps don't show up and your using default clocks it looks like.

How would a 'large pool' differentiate that from simply being a 'backup' pool?
Would that really mean that no one should use 'large pools' as backups coz they will ban you or reject your shares ...

Actually I get unexpected middle of the round share's rejected by DeepBit that is my backup ...

Right, I didn't say it was good practice, sanctioned, moral, appropriate or anything else of the sort. Just casting a purely objective observation about what it did.

Note that some pool operators don't really like this behavior because it increases pool load during LPs (and thus stales or other pool users) without actually using the pool much. From what I know some pools even ban you if you do this (submit less than some threshold of shares for a given amount of requested work / long polls).

Hm, as of a week ago there was no code base that actually works on the 1.15y IIUC. Nelisky just had committed some preparatory changes for that, but not the actual thing yet.
I'm not sure if this has changed in the meantime, but from what I know (and I'm not really involved deeply here), it could be possible that 2.3.6 simply doesn't support the 1.15y yet. Ask nelisky for details.

Con, Luke,

this is from another thread to sort out issues with a throttling BFL Single I have in my 5-unit setup:

In short, what I am observing is: the one throttling device reproducibly reduces the all-time-average hashrate of the non-throttling devices reported by cgminer (Linux, 2.3.5). I am not sure whether this is just a measurement error or if my assumption with the stalling communication thread causing lags sounds reasonable.

Con, you're da Linux scheduler guru. Any ideas? Since you have no Singles at hand (and even more no reliably throttling ones), I'd try to implement and test potential fixes myself if you had some ideas. Or do you have a throttling one, Luke?


Thanks, zefir

I`m using now 2.3.6, thats why i know the error code
i`ll ask nelisky on ztex hardware thread.

In my limited ztex knowledge (nelisky wrote that and I don't have one)
The 15y board supported was added with 2.3.6
(It was in 2.3.5 also but best not to use 2.3.5)

But not in 2.3.4 or earlier

First guess (from the README):
export DISPLAY=:0

(if not, then it becomes a question of how you didn't setup the GUI or other such things)

I would also suggest you use the current version.

I have two asus 5770's running on stock Ubuntu 11.04.  aticonfig can read the gpu temps just fine, but these stats don't appear in cgminer.  I've tried numerous versions of cgminer, AMD sdk's, all with the same results.

Anyone have any ideas what's causing this?

someone help me via pm!!! i tried to update my video drivers and i eneded up installing sdk 2.6, So i followed some advanced removal steps that i stated for me to delete some /windows/inf .inf files, And when i went to install sdk 2.4 It was fine, But when trying to install the display drivers, I ALWAYS get ".inf file not found blah blah cannot install"

I've even tried a system restore, And that device manager install thing doesnt work!, Please help me!, My hashing power and main computer are practically gone!!!

Any1 can tell me haw to use zteX board? i`m getting error -3 in the beggining. i got 15y board.

Hmm... Problem's gone now. Nevermind then, sorry for bothering you. I think it has to do with my installation of ntpd while using cgminer.

What build options did you use or

What is the output of one of:
1) java API config
or
2) echo -n config | nc -4 127.0.0.1 4028 ; echo

If you are windows and 1) doesn't work or you have problems getting either to work just ask

That is not a dumb question at all and in fact you are right in thinking there may be an advantage, but it is complicated.

The reason comes down to what happens at longpoll time. A longpoll occurs when the block on the network has changed. This is the time you are most likely to submit stale shares because you are working on the old block still when the new block is already spreading throughout the network. Furthermore, once the longpoll hits, you have to throw out all work and ask your pool(s) for more work so it is the time you are most likely to have a drop in hashrate while waiting for the new work (this is why the older releases of cgminer used to say waiting for fresh work).

Now because cgminer checks longpolls from *any* pool you are connected to now, it can tell when the block changes on the network often faster than your primary pool finds out because you may be connected to the pool which discovered the block as well. So cgminer then knows to stop working on anything from that old block in anticipation that it will be wasted work. However until your primary pool discovers that the block has changed, you cannot actually get useful work from it. The beauty of longpoll, though, is that it is actually giving cgminer work as well, so you will be getting work from the backup pools to fill in the trough period until your primary pool finds out the block has changed. For this to be useful, though, you do actually have to be happy for the backup pools to get some of your shares over time, and therefore enough shares have to accumulate to eventually give you a payout from them. If you enable the --failover-only option, you lose this benefit because not only will cgminer stop working on the old block before your primary pool discovers the block has changed, but you won't even accept any work your primary pool gives you until then, so it will dip in hashrate for longer.

There is also one other potential use that I'm not sure if I should point out or not

If you see this:

You now have a way of knowing which pool is LIKELY (though not surely) to have found that block if you have most of the major pools in your set up. This means you now have a way to *cough* choose who to hop to, if you're so inclined...
