initial results of fresh compile and mining at givemecoins using only -X 15 and --diff .5 with no oc or firmware tweaking ... just stock ...

I don't need to use --diff 0.5 in the latest version. Depends on the pool you are mining. On nicehash or p2pool.pl , run without the --diff parameter.

with giveme coins - it still requires it ...

they havent changed anything in their stratum code as far as i know ...

here is the latest ...

so its settling just under the 24200 mark ... a little bit more than it would have usually done at the same level with the previous v60 ...

giveme coins is averaging about 23000 mark for this one machine ... though it is very difficult to get any stable reading from the pool ...

when the mining stabalizes in the next 15-30mins - that will show a more accurate figure ...
i like the temp and fan displays too - nice ... why not shorten T=xx F=xx ? ...
what is this new part also - tid? ...

Thread id. I think I should remove it. The temps and fanspeed is only working in the linux version. The changes in the output is written by t-nelson, and I have merged his changes into my fork.

i think you should also ...

if the thread id is useful to the general public - then leave it ... but if we cant use that info as miners ( or general public ) as info for the miners - then it doesnt need to be there in my opinion mate ...

and temp / fan in linux only? ... that would be a first for linux to have wouldnt it? ... nice merge in my opinion ... ...

And thanks for your continued support of ccminer. Not sure if it's relevant as you don't really seem interested, but the low CPU overhead changes you made to ethminer reduce hashrate by like 20% when you have 2+ GPUs.

https://forum.ethereum.org/discussion/2227/cuda-miner/p8

The low CPU overhead changes by sp_ didn't make it eventually into latest build in favor of tpruvot's alternative. Only sp_'s keccak optimization is still in, although it doesn't really make a difference.

As for the original reason Ethereum was referenced in this thread; I know somebody is building stratum support for ethminer. I was approached for the job last week but declined, so they found somebody else.

It's in the windows version as well if you build 64bit and not x86.
The reason is that NVIDIA has removed the support for the API calls in the 32bit application.
On windows the 64bit builds are hashing slower than the 32 bit builds.

I know it's a dead horse by now, but have you tried having the first few lines of ccminer fixed instead of scrolling and put some info like temp and fan speed there, like sg/cgminer? The issue with the first approach was that linux wouldn't support it but surely there's another way.

when the mining stabalizes in the next 15-30mins - that will show a more accurate figure ...
i like the temp and fan displays too - nice ... why not shorten T=xx F=xx ? ...
what is this new part also - tid? ...
#crysx

Thread id. I think I should remove it. The temps and fanspeed is only working in the linux version. The changes in the output is written by t-nelson, and I have merged his changes into my fork.

I know it's a dead horse by now, but have you tried having the first few lines of ccminer fixed instead of scrolling and put some info like temp and fan speed there, like sg/cgminer? The issue with the first approach was that linux wouldn't support it but surely there's another way.

i have suggested these requests a very long time ago ... as in the 'stats candy' of sgminer but the performance of ccminer in one package ...

i think it will require a full rebuild of ccminer if it comes to that - maybe? ...

i like the way sgminer prints stats and scrolls the active stats below the cumulative / current stats ...

no one has come to the party with this - and i think it is due to a full rewrite of ccminer ...

o well - we can hope ...

+150kh/s on 750ti
+3MH/s on 980  

Which algo?  On latest sp_'s github?

lyra2rev2, not released yet...

id pay for that - if its private djm34? ...

150KH increase is nice on a 750ti ...

Eagerly waiting

I have only added 500KHASH on the 980 (sp-mod 61-git) Which algos did you rewrite? And will you make it public?

rewrote lyra2 code:

and temp / fan in linux only? ... that would be a first for linux to have wouldnt it? ... nice merge in my opinion ... ...

It's in the windows version as well if you build 64bit and not x86.
The reason is that NVIDIA has removed the support for the API calls in the 32bit application.
On windows the 64bit builds are hashing slower than the 32 bit builds.

i was playing with a little humour there sp ...

usually its linux thats well behind windows based advances that nvidia bring out ...

but i understand why now ...

Good job.
I guess the new kernal is using more power?

yes, the 980 runs at 110% tpd and the 750ti close to 95% (on my gainward stock).
Honestly I will try to backport (if possible... not entirely obvious though, the new kernel relies on warp shuffle technique) some of the change to amd before releasing it, I don't want to create more imbalance...
