Topic: [ANN] cudaMiner & ccMiner CUDA based mining applications [Windows/Linux/MacOSX] - page 818. (Read 3426922 times)

I wouldn't make so broad statements.

I have implemented a GPU accelerated sieve of erathostenes myself as a tutorial project, and it was faster than on the CPU. But it was for small prime numbers (think <  2^^32) and the acceleration wasn't that great.

But doing the same for BIG numbers (integers with 1024 bits or so) requires specialized maths libraries, ported over to GPU. This is effort.

there is prior art in this area though: the gpuPrime and prime grid projects (I think its a Boinc project). Maybe one could take some inspiration from there (and also code, license permitting)

I exchange two bat for two coins.Hey body do u have utc max and vet bat

I would say commit 176 is perfect!

@cbuchner1

Good work on your CUDA miner for maxcoin on such a short notice.

Nvidia's GTX 780 Ti Classified is about 8x (overall) faster than Intel's i7-4770K (Haswell using AVX2 instructions)
Sieving performance on the Ti was a little bit disappointing when compared to Haswell.

Karatsuba followed by Montgomery Reduction seems to work best on Haswell (GMP modular exponentiation)

Hey Christian, just a question


Are you thinking about implementing Protoshare or not at all ?

- Calculating prime number with GPU is a given problem from long ago. Almost a few decades and nobody was able to do it. I don't think we will have it soon.

compulsory hoarding, eh?

where are you currently buying hardware for bitcoin in the Euro zone?

Christian

I just checked and my cudaMiner folder takes up 13 GB's and I have 165 different cudaMiner binaries compiled since December.

cbuchner1: Awesome work on the maxcoin release. I will surely be sending over some coins when I get my internet back (bad weather here, just barely online via mobile). You make the 'green team' proud! 

Earlier there was a post about new/next cudaminer development opportunities, and I have two suggestions to make:

Protoshares - popular, highly valued, already has a gpu miner available (only binary I think), though it appears to be far from reaching optimal performance on nvidia, so likely opencl only at the moment. My single GTX 770 earns me a little over .5 PTS a day (1GH pool) and only using 70% power. (1PTS trades for 0.015BTC)

Primecoin - popular, currently CPU only (suspecting this one would prove to be a challenge in terms of optimizing for GPU at all, but perhaps cuda specifically would make it worthwile). It's not highly valued, but stable and also very popular. The potential on this one is for a GPU implementation to break into new performance figures, thus making it largely profitable for a relative time.

I hope this comes across as helpful. I would love to help with code but lack the skill-set, so instead I'm looking to save Christian's time in going through all the altcoins to work out the most interesting (or challenging) opportunities ahead. I'll be happy to to test any development version to support new coins, however broken or buggy a release is - but I only take binaries though

On Riecoin that was just mentioned: It's technically very similar to Primecoin, but yet to be launched. Interesting opportunity if it is found to reach a good coin value for the relative performance in GPU mining, but I don't see that it has the hype or following to produce the same returns as the ones I mentioned above (or even a fraction of Maxcoin for that matter).

Cheers!

yes, that is a github feature. I think they have RSS feeds and email notification.

I commit a lot of dysfunctional crap though,  so be warned.

my card is gtx780 How can I make a bat to mine max and utc? please give me two bat Thanks.

It was worst this morning... I went to buy a new graphic card, at first the bitcoin was at 413euros... hopefully when I was about to pay, it was at 470euro... well this isn't a really good deal but still...
Finally bought a MSI R9-290x Gaming edition... hope there won't be any problem to have it in the same computer as the gtx780ti...

Christian, is it possible to subscribe to your git account, so that I get an update for the new versions?

With that being said, mining UTC at 400kh/s gives me 0.016btc/day, VTC at 300kh/s 0.014btc and maxcoin at 200mh/s 0.017btc a day vs scrypt's 0.012btc/day with the absolute best coins and a way higher power draw. (UTC is really light on power, like all scrypt jane coins, same with max, vtc and protoshares). Yeah, forgot about protoshares, that's pretty dan good too: 2100cpm = 0.73pts/day.

Thanks for the help guys...

Cudaminer only crashes when mining vtc or utc, maxcoin is fine...1150mv 1306mhz core and 3665mhz mem, 70c or less whilst mining.
