I reverted the jh512 change and the rotr change.

That is suspect: quark jh and x11 bmw were redefining rotr32 with the original sph code, while all the rest use the cuda_helper version which has specific cuda code.
If the cuda specific code is slower, than we should replace the rotr32 definition in cuda_helper because all the other files will benefit from it.
But I highly doubt that it's the case: cuda_helper has been worked on for months and it can't be slower than sph code, unless the compiler is so smart that it can detect it's a rotate and replace it with even more optimized code.

In brief, I wouldn't reput the double definitions (it's a warning...) but adjust the cuda_helper version, so we have the best rotr32 on all algos.

The compiler is smart. it converts the

ROTL32c(x, n) ((x) << (n)) | ((x) >> (32 - (n)))

to one assembly instrucion. the funnelshift. Take a look at the generated .ptx code in the release folder.


But in the lyra2v2 algo I now get +50KHASH on the gtx 970, so sometimes it's faster to use the method in cuda helper.

I think it's because the compiler is  unable to precalculate and remove instructions that operate on contant data when we use inline asm. rotl(const,x)

with the current commit (reverting quark_jh and quark_skein but not groestl) quark is a bit faster... that's puzzling :-)

"in the lyra2v2 algo I now get +50KHASH on the gtx 970"
but lyra2v2 is not using quark/, Algo256/ or groestl... still puzzled ;-)

yes, but you also changed the rotl32 in the blake256 And it seems to be a little bether there. So I kept it.

I see. But that means that x11 (and others based on the same file) should also be faster :-)

For those that follow this thread in the hopes that some improvements will happen to Monero (i.e. cryptonight) nvidia mining, the Monero Forum Funding system for djm34's proposed work is up and running:

well, that takes you to a link to the link, here's a direct:

Sorry for the off topic. This thread has become the hotspot for this stuff though.

x11 uses blake 512.

the 256 algos are neoscrypt,lyra, and lyra2

Submitted a speedup 50KHASH in x11 on the 980ti. With code from the klaus_t fork. and constant rotates.

needs to include cuda_vector.h instead of cuda_helper.h

I didn't modify the includes.
Furthermore, it compiles fine on Linux...
I know the build files on windows have been enhanced recently, maybe it's related to that.
I can't help because I never built on win.

The header deps are a mess.  Odds are it was pulled in by some other header on Linux and you got (un?)lucky.

Seems on par with 65 on 750ti and 960.  At least no regression noticeable.

GIMP ON YIIMP--

For the last couple hours I mined MUE coin (Monetary Unit) on YiiMP (yiimp.ccminer.org).  MUE is a quark algorithm coin, and according to CoinWarz, currently capable of producing ~200-400 dollars a day in mining revenue.  There must be a decimal place or two missing in the calculation!    I mined over 1000 MUE in the space of time that I spent on YiiMP, but they are currenly worth about 15 satoshis each.  I will be earning about .00015 BTC on the exchange when my MUE coins mature, I think.  Not so sure! 

Every block that I hit, I got all the coins save the pool share. Somehow, CoinWarz led me to believe that I'd be earning 100X more, at least.  I solved ~40 blocks at 40 MUE coins per block.  Because YiiMP is more or less a hobby/experimental pool, it was as if I was solomining.  There was no other miner to share the blocks with me, just the 1% pool share to deduct.

If I could only find the right coin...

MonetaryUnit (MUE)
Exchange volume (24h): 0.02 BTC.

No offense, but I still chuckle everytime when I see a multipool picking up coins with 0 volume.

If I ever launch a coin it will have coin maturity of about a week and it will change the algo every few weeks just to throw multipools off.

Volume bro... Mining a dead coin. More hashrate you have, the bigger coins you have to mine. Putting aside volume, large amounts of hashrate instantly destroy the difficulty on small coins making them pointless to mine.
