Topic: [XPM] Working on a GPU miner for Primecoin - page 13. (Read 102789 times)
Okay the new GPU sieve is done, and using a single core of an HD6990 it's around 25x faster than a single CPU core of an x6 1055T. Next up: debugging and optimizing the primality tests.
looking forward to this
Can't wait. 
Nice, let the mining begin very soon 
I'm working on a major optimization of the GPU sieve. Should be ready today, and the sieve should run 5-10x faster.
Today - it's good! 
Hoping for the best!!!

Any news on release?
thank you for devoting time to making a GPU miner
Watching this Awesomeness 
Nice.
Just putting it out here for public record.

This is great news...
Hope we can do the beta testing soon
Thanks

You could try commenting out the bodies of functions, checking if compiling with optimization works and repeating until you find the code it's falling over on.
Yep, that's what I ended up doing and I did find and fix the problem.
I agree with that to an extent. But I also think that one should weigh in quite a few factors before taking such a risk, IE reputation of founder, profitability (in this instance), eagerness to obtain the product, etc. If all of those factors (most importantly reputation) come to a positive conclusion, then I think you should be willing to pay what it's worth. If it's not worth it to you, then let the project be, but I don't really see a reason to bash others for supporting.
I paid my donation, so I'm definitely not bashing anyone;) I was replying to refer_2_me's comment that there should be a level of accountability, when in this case there actually isn't. mtrlt can take our money and run, and that's his prerogative. Maybe some will pursue him legally, he'll definitely be scorned, but there's virtually no accountability. We have sent our donation, and we trust that he will deliver, whether that trust is misplaced or not.
While I agree with you about developers salaries, it's not the point of the discussion. In your jobs, there is a level of accountability which isn't present here.
There's no "accountability" in open source software - and let's not kid ourselves, this is FOSS. That the developer is taking donations for a prerelease does not change the fact that it will be released under GPL or similar licensing, so there's no "company" to shout at. Everyone needs to disconnect from their pseudoreality where they equate sending a donation to a FOSS developer to paying a company for a piece of software. As KickStarter and Indiegogo have demonstrated, even the legal framework around donating to an incomplete piece of software/hardware is murky, and backers may find themselves fresh out of luck with no legal recourse to reclaim their funds.

I'm now working on getting the Fermat primality test done on the GPU. Everything but the bignum modulo operation is already done, but there's a problem: The OpenCL compiler crashes when I try to compile with optimizations turned on. Without optimizations the code compiles, but that's obviously not a good solution. I will try updating my graphics drivers.
I haven't forgotten about testing on a slow CPU + overkill GPU rig, but I still have some problems using multiple GPUs.

If it would be possible "hack" GPU that is recognize like multiple CPU it would be a solution, but It's impossible. So better use Intel Xeon PHI, but is not x64 architecture as I know.
watching this thread ;p
