OFFICIAL CGMINER mining software thread for linux/win/osx/mips/arm/r-pi 4.11.1

[-ck]

My E: went from ~175% to 1200% after about 10k shares. Is that what you were expecting?

My efficiency is through the roof with this new version.

miner with one GPU after 13k shares: 5316%
miner with three GPUs after 40k shares: 50336%
miner with four GPUs after 56k shares: 4516%

the 2nd one looks funny to me, but it's what cgminer is reporting.

M

Yes this is precisely what's expected in anticipation of much faster hardware (if asics ever appear). If you mine solidly on one reliable efficient pool, the efficiency can reach legendary proportions.

After every new block and longpool A sould incerase.

I assume you mean Q, and that does look odd, but my Q is much higher, which may mean my pool doesn't support nrolltime.  That said, m Q starts at 4 (gets work from the main pool and 3 backups).  That is even with --failover-only specified.  Are you mining with only one pool?  If not, did you compile, or download a binary?

[rav3n_pl]

I`m mining LTC on my P2pool node. Binary downloaded form #1 post.

Edit: Yes, ofc i mean Q not A

Does anyone know why CGminer (fresh copy) Keeps changing my clocks?!!

Sounds like there is a config file somewhere.  I haven't messed with config files, but presumably you didn't delete the directory where the fresh copy was placed or the config file is stored in you working directory, outside of the directory where the fresh copy of cgminer has been place.

[d3m0n1q_733rz]

Just a thought for the Litecoin Scrypt OpenCL miner.  Combine the multiple uint4 vectors into uint8 so that the SIMD processors can do their job more efficiently.  It will have the same number of reads and writes, but the instructions should be fewer.  This is just a theory anyway.  I would try it myself, but it requires a modification to almost the entire code that I'm not capable of myself.  There's just too many offsets and the code is designed using the outdated w, x, y and z vectors instead of s0 - s3 so expanding upon it is difficult at best.
I had managed about half of it last night until I got to the bottom where the W and w variables came together.  One of those needs to be changed so that they can be told apart from each other.
But yeah, if the same instructions are going to be used on two (or more) sets of vector 4 types, they need to be combined for simplicity.

[Nite69]

Git log tells me there was some problem with the patch I submitted. Can you (or someone) clarify where the problem was?

It crashes other rigs completely. Presumably the -lack- of a gpumap breaks it completely and tries to tie everything to device 0. I'll look into re-importing your patch and making it work.

Oh, that's not good..
I think it just needs one

Code:

if (gpus[gpu].mapped)

, but maybe better if you do it.

Lord knows why, but cgminer's default behaviour is to load cgminer.conf whether it's specified in the cmd line or not. if you specify a different conf file, it'll load both.

Lord knows why, but cgminer's default behaviour is to load cgminer.conf whether it's specified in the cmd line or not. if you specify a different conf file, it'll load both.

The reasoning behind it is quit simple:
If you save your config using the default save file, cgminer will always load it next time.

The problem is of course is if you put a 'cgminer.conf' in the place where it looks for the default it will always load it

Linux: ~/.cgminer/cgminer.conf
Windows: current directory: cgminer.conf

If you saved it using cgminer screen keys to the default location (press S and W), then of course it makes sense.

... and yes this has been explained in this thread a few times.

And is the first paragraph at the beginning of the "EXECUTIVE SUMMARY ON USAGE:" in the README

After saving configuration from the menu, you do not need to give cgminer any
arguments and it will load your configuration.

Though I'm not saying I like it - but it definitely has it's use ...

[-ck]

On second thought, there may be a bug here... will investigate tomorrow.

About this, I have confirmed there is a bug in 2.7 where it can get into a situation where it can't queue enough work and continually thinks one pool is not providing enough work. I have fixed this in git but this has introduced a new crash which kano is trying to help me track down. In the meantime, anyone on 2.7.0 should probably enable --failover-only to mitigate its problems.

[sharky112065]

Updated Windows compile instructions:

Hopefully this will be included in the next release of cgminer as well.

This was tested on both Windows 7 and Windows XP.

Could use a comment on this.

Other vector sizes have been tried. They suck.

Hi! Maybe I found a problem with 2.7.0, which made me revert back to my prevoius 2.6.4.

Here it is my log.  My pool strategy is failover, from my config file ("failover" : true).

It looks like also pool1 (ABCpool) is having a problem, so cgminer starts getting work from, and sending shares to, all the other pools. I've never seen so much spread before (I mean: the activity to the selected pool, pool1, is so little!), but I'm fine with it.

The behaviour remains the same (I cut the log), then the problem: I switch to pool2 (deepbit) sending, as usual, an API request to cgminer. Cgminer obeys ("Connected to http://deepbit..."), pool2 (deepbit) has no problem at all (verified), but despite it cgminer keeps on sending shares everywhere!

After some minutes, I quitted and reverted back to 2.6.4.

HTH.
Thanks for everything.

On second thought, there may be a bug here... will investigate tomorrow.

About this, I have confirmed there is a bug in 2.7 where it can get into a situation where it can't queue enough work and continually thinks one pool is not providing enough work. I have fixed this in git but this has introduced a new crash which kano is trying to help me track down. In the meantime, anyone on 2.7.0 should probably enable --failover-only to mitigate its problems.
