You meen all the LBRY sp-mod kernels with 0% increase right? What's the point. 0% increase as you said.

0% increase, but higher profit poolside.

Yes. I will release the donation code later.

My latest Nexus mod is compiled with cuda 6.1.

Why do you think NVIDIA release a new compute version?  You just need to rewrite abit for more speed.

TSIV had a shuffle kernel right after the launch of lyra2v2. I think Djm34 had one as well.  Marvellous code doesn't give you the profit, speed and stabillity does.

But you got payed. It was a job. You based your work on other opensource coders and got payed for it.  Why don't you compile a binary and we can compare the assembly code. I want you to compile it with the compiler and cuda version of your choice.
Please add it to your github. exefile.

Because when I compile your work, I get a 6% slower LBRY Kernel. I might have missed something?? The speed is not there. Are you compiling with compute 6.1?

The first opensource LBRY GPU kernel and ccminer integration  was done by me 15-16 Jul 2016 (github). 2 days later tvpruvot released his version of the kernel.
After that I have been doing private modded kernels with more speed. It's normal to get payed when you do a job. You got payed by the LBRY team in october (5 months later).
(because at the time the LBRY sp-mod #2 was  around 15% faster than the opensource)

You have never released an official binary of your work. (ccminer 2.0 is using your kernel, but with slow results) That's why I use the profiler to measure the real speed.

6months have passed and LBRY is profitable to mine again...

Now it's time to add another 10% ..

Because the first version I released yesterday had a bug with 100% cpu usage. I have updated the .7z file this morning with a working version.

Why don't you extract the ptx, you will see that it is different.
I left the exe wide open.

I get +2-6% faster on all the cards I have tested. Gtx 1060 3gb, gtx 1070, gtx 970.

100% tdp, small oc. -500 on the memory.


My kernel vs your kernel (gtx 1060 3gb) same launch config, compiled with the same compiler (cuda 7.5), same driver:



You can profile it yourself.

I have profiled with the same intensity. Run 2 versions on a pool. Mine is faster

My kernel need more power.

I tested on the 1060 3gb.

Because it's 6% faster than the alexia miner and 6 cards work.
14% faster than ccminer 2.0

cpu version , and no cpu.

Here are my results on the 1060 3gb. lbry sp-mod #6 fixed.

(vs my public build of the alexis miner (decred). (compute 5.0 and compute 5.2  cuda 7.5) compute 6.1 is slower.

Same clocks, Same intensity, same config.

The profiler show that my kernel is 5% faster, but the displayed hashrate is only 186.2 MHASH vs 184MHASH

If you run it it longer, the alexis miner hashrate is dropping.
If you run with more than 3 cards, the alexis miner is showing a lower hashrate on card 4-6. and total hash.  Sometimes the 5th and the 6th card is gone from the totalhash and they don't work/will never start even after 10 minutes.

I have uploaded another fixed version without 100% cpu usage.

please test it.

No. Profile it.  My kernel is 6% faster on the 1070 with intensity 28 and 100% tdp. G1 gaming.

I use nvprof.

I will update the exe with a cpu fix later.

Add 16 gig of virtual memory. If it doesn't work, reduce the intensity to 28 or.lower

Profit with the LBRY sp-mod

520mhash... nice

Are you running with reduced tdp? 80% tdp will reduce.the hashrate by 5-10% on the gtx 1070 (sp-mod #6)
