did a rapid test with lyra2, the cpu usage is awfully high (I have a noisy cpu cooler...) 50% usage... against 5~7% in my version.

what did you do ?  
 
I was thinking, may-be I could use tpruvot interface, but 50% cpu usage is a big red flag for me... so please fix this...
(not the case for x11... though, but I don't use x11...)

You should merge his interface and api I'm sure that they aren't the ones causing the CPU usage, but I've noticed it too on lyra2.

it should come from the interface I use the same code in the legacy interface and the cpu usage is normal...
Main problem for me to move in (beside cpu usage), is the fact that m7 has been ditched    and I would need to rewrite everything (again) again on the interface, and that was particularly painful the first time...

m7 has been... skipped

Using cudaDeviceSynchronize() was probably not a good idea.

i was about to say : its in lyra2_cpu_hash_32

and i think you can even remove the line else, no impact on hashrate

indeed much better (I did saw that, but tried to remove all the (my)cudasynchronize and it didn't change anything, putting them back works) actually.

Time to make a neoscrypt port for NVIDIA. Can we beat the opencl code by WOLF0?

(nicehash)

NeoScrypt    3341   0.2021 GH/s   4.7595 BTC/GH/Day  738%   3.5289 BTC/GH/Day   5.2900 BTC/GH/Day   5.2900 BTC/GH/Day   View orders

now this would be VERY nice ...

i am changing ALL the cards to 750ti OC ( Gigabyte to be exact ) and will be testing it with the initial 11 cards i have currently ...

i will be more than willing to guinea pig and test neoscrypt on these cards the moment you have something out ...

not to sound greedy, but donations are a better incentive than guinea pig  

[tbearhere]

Version 20 is here (windows executable):

Faster x11 (+100KHASH(750ti))
faster x13,x14,x15,x17
fixed hashing for old cards.

source

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


One exe this time. Compiled for compute30,32,35,50,52

some algos don't work.
someone say WOLF0 open source...gotta find that.  
Edit: I can't find it.

about the supported cards, ive seen yesterday a bunch of new Quadro card made for the office... and all are SM5.0, some with 2GB, some with 4GB and more... But only a few are affordable (<200€) like the K620

http://www.pny.com/nvidia_quadro_k620 ... a bit curious about the perfs

384cores... that's a little more than half the number of core of the 750ti...
128bit mem bus
32-bit floating point...


I fail to see the interest...

Can you give a guess on the hash rate for the 750ti.

Once it is written, I will, but right now, it is a bit prematurate

I have some improvements in the lyra2RE implementation, but will keep the kernals private.

hehehe ... i know this ...

which is why MY version of 'guinea pig' is to mine FOR you as a donation to the btc address via westhash ( as this is the closest to adelaide australia ) ...

ive done this many times before - and it works ... my entire farm will be pointed to the donation btc address - which usually buys you a beer or two hehehe ...

i think thats better than mining for myself - transferring into my wallet - then transferring into your wallet as a donation ... AND you can keep track of it by watching the progress at westhash ... ( hint Wolf0 just recently ) ...

i mainly mine x11 - which is my preferred algo and the main one for granitecoin - but have no issues setting the farm to the algo that needs doing ... if only we can get a crap load more hashes for nvidia cards with x11 ...

btw - you guys and the work you are all doing is awesome ...

im happy to give details of the farm if you need them ...

Hamsterwheel payment plan-

This sounds interesting.  I have two 6-card 750ti rigs.  DJM34, I'd be willing to point them to your payment address for a crack at running alpha/beta neoscrypt kernels.  My rigs are Ubuntu 14.04.1, 64 bit.  Post something if you are interested.
