CCminer(SP-MOD) Modded GPU kernels.

[joblo]

i do like the office pc miner!  what cards are in there? they seem smaller than even the single fan evga type.

They are the EVGA 750ti's SC.  Single fan and no 6pin.  Powered USB risers FTW!

what's the word on card orientation? I remember reading somewhere that the specific type of fan mount on GPUs was made for the card to be in the horizontal position (as if it were installed in a standard tower desktop), and that having them in the vertical orientation (such as in your rig) is what causes the fans to fail early.

rumor / misinformation?

Hmmm - I never heard the card/fan orientation rumor.  I have been running the cards in an open case vertical design now for about a year with no issues.  I dust the system about once every other month with canned air.  Other than that no problems.

I think it's rumour. Orientation makes sense with a large spinning mass. If horizontal the bearings don't have to support
the mass and wear longer. It applied to hard drives many years ago when they were much larger and less
reliable but a GPU fan is just too light to matter.

isn't it pRotoshares, not pHotoshares?

yeah, you are right. The Momentum algorithm.

I have added the C11 algo from the tpruvot branch. I have replaced all the kernals with my modded kernals, and the speed is faster.

No it's bitcredits:

but this algo is used in other coins as well. The momentum algo.

not momentum algo related but the inertia on this thread is huge....
this is this coin: https://bitcointalk.org/index.php?topic=1037244.0

The AMD 280x  does about 4,400 cpm . Not sure how to convert this number.

When you say 420 MHash, that's individual sha512 executions that you're measuring?

Assuming it is, then:

In expectation, there are 2 collisions per "round" of momentum (creating 2^26 hashes).  Those create 4 "reported" collisions because they're counted symmetrically -- A colliding with B also lets you test B colliding with A.

So you should be getting *roughly* 1500 CPM on a 750ti.  The older miners were at about 800-900cpm.

NaN's miner on a 280x AMD gets about 6700 @ 200+ watts.

But I'm confused about the code - it seems to just be doing the sha hashing, not the collision-finding part of momentum?

Ahhhh, got it.  Credits.  Not bitcredits.

I might add bitcredits later.

is this your code dga?

New release.


-Faster quark (optimized bmw-512)
-Added the credit algorithm (from the djm34 branch)
-Added the c11 algorithm(from the tprovot branch, but all kernals are replaced)

1.5.56(sp-MOD) is available here: (22-07-2015)

https://github.com/sp-hash/ccminer/releases/

The sourcecode is available here:

https://github.com/sp-hash/ccminer

[sp_]

did some optimization on quark: +75% (roughly)  
yeah... well  

10 Mh/s on 750Ti?? That's really great!!
will you merge the mods, make a new repo or sell it?

well... that was a bug it is rather +1MH/s for 980/780 and 0.5MH/s for the 750ti

Since you posted your increase I have almost reached your increases in the opensourceminer.

Quark increase in the sp-mod written by me:

1.5.50(sp-mod) 29-may-2015

gtx 970: 15500  
gtx 750ti: 5650    

1.5.56(sp-mod) 22-july-2015

16254 +754KHASH (4.8%)
5920  +270khash (4.8%)

haven't checked, but it is probably still there

Credits looks relatively unused and c11 doesn't seem to have a coin besides protoshares that died out. Is that true?

https://github.com/dave-andersen/cudapts

Yup.  I think I committed an optimization or two to the cudaptsx version (x == xpassthrough, for ypool):

https://github.com/dave-andersen/cudaptsx/blob/master/xptMiner/gpuhash.cu

It's not a fast algorithm for doing the collision finding.  I wrote it pre-Maxwell, so computing the SHA was the bottleneck and it wasn't worth optimizing to do something faster.  With Maxwell, the sha is fast enough that random global memory accesses will be very bad.

Version still shows 1.5.55. Had to doublecheck to make sure i was using the corect version.
Other than that it looks good on the major algos so far. Noticeable increase on quark although
I haven't measured it yet.

Edit: 750ti +100

thanks. I forgot to submit the release number to git. The exe should be ok though.

Interesting is that I reach more hash with 55r, instead of56 on 750TI OCed

Yeah, doing a lot of digging. Yiimp doesn't support BTC payouts and Chaincoin doesn't have an exchange yet. I haven't looked at Flaxscript yet.


Edit: Cryptopia has CHC exchange, but the volume is very low.
