Yaamp has added the skein and the groestl algos...

VERSION 44e (my 5th compilation on Linux, your latest git)
Skein rocks on Yaamp at 452,800kh/s for my 6x750ti FTW rig, or 75,000+ kh/s per 750ti.  These hash rates are similar to Whirlpoolx rates.
Groestl only gives me rejects on Yaamp, 100% red "booooos".  Might be poolside...
 These two algos have not seen much use yet, payout is currently low.       --scryptr

How much faster is SKEIN than the 1.6.1 ? (tpruvot version)


75MHASH is around 25 times faster than x11. Yamp is paying 0.0152 per GHASH. is 0.0152 *25 =0,38 per GHASH (x11 adusted rate )

mining x11 directly will only give you 0.199 per GHASH with the current rates..

NEW ALGOS--

I agree.  However, no-one is getting shares for Groestl accepted at Yaamp just now.  I saw sgminer v5.1.1 receiving 100% rejects, and CPUminer v2.3.2 receiving 100% rejects, and with your code I got the same.

Looks like a poolside problem.

I'll try tpruvot's miner sometime today.

Another note, my quark rate dropped slightly with this hours-old build, 36600 to about 36430 for the rig.

I have trouble making sense of Yaamps graphs, charts, and payout rates.  Staying on their website is a real load for my system, also.  It cuts mining performance 20-25%.              --scryptr

The same here scryptr.... yaamp cuts mining performance 20-25%.

Hmmmm...

To clarify, yaamp's website has so many scripts running that it slows down my GTX 960 if I am watching the website and mining with my GTX 960 at the same time.  My dedicated, headless rigs are not affected by this.       --scryptr

p.s.  sp_'s latest builds on v44 are top performers.  I checked out tpruvot's v 1.6.1 and KlausT's v 3.0 and they lag behind on most algos in kh/s.  Both authors focus on other areas besides top performance, and both have fixed coding errors for other coders, as well.  I am getting 9.4Mh/s with my GTX 960 SSC for Quark, at default intensity with v44e by sp_hash.       --scryptr

Man. Is that firefox?

probably - mine does it too ...

not as bad as in chrome ...

this is all in linux too ...

now THAT is news ...

will test with the farm when it comes out of rental ...

I have added a threads per gpu parameter just like in sgminer.  ex: -g 2

Some algos get a boost.

Most impovement on compute 5.2 devices. (960,970,980)

x11 with -g 2 on the 750 ti, the performance is reduced by 0.5MHASH.
The parameter is not always producing higher hashrates.


The stats are reported by each thread, so some more work is needed. (run with -q, so the screen is not flooded with hashrates)


Note that -g 2 will reduce the intensity by one. this can be overridden with the -i parameter.


I will build release 45 now.

looks like there is a bug in build 45 on some rigs. only 2 of 6 cards are hashing. working on it

[tbearhere]

What is a good difficulty setting for a 6 card 750ti rig on Qubit. Thx

[Nubminer]

here are my numbers with the current build 45

Any suggestions to improve my output would be greatly appreciated

Using this startup

ccminer -i 21 -a x11 -o stratum+tcp://us-east1.dash.miningpoolhub.com:20465 -u user -p d=0.1

using precisionX to bump the GPU to +266 MHz
 
seems to do great rapid acceptance fo the first 7 then after that each line takes awhile like 10 seconds or more

the current compile of 45 actually broke x11 for the systems here sp ...

quark runs nicely though ...

out of memory and core dump errors ... and 44 is fine with those algos though ...

[go6ooo1212]

Release 45 gives twice slower speed on qubit with bunch of CPU validation errors:

[sp_]

fixed the bug, and corrected the hashrate statistics. Please try the new version.

Get the latest version and try x11 with -g 4!

the 750ti is peaking at 3200 at standard clocks!

edit:

in benchmark mode, but on the pool I get some does not validate on the cpu...

What about without the -g parameter?

Looks like the -g need some more work. It might not work on all algos..

the -g 4 parameter ( actually -g 2 also ) just doesnt work - it drops just after it starts with no error message that i can see ...

take the -g 4 parameter out - and its all ok with this newer build ... but only on some of the machines in the farm ...

with others - v44 needed to be reinstated due to v45 giving errors with the aforementioned - core dump and memory out errors ...

will get to this tomorrow - as its late here now and sleep awaits ...

tanx again sp ...

Any idea about the expected payouts on yaamp for quark?
