Donations to open source a GPU Protoshares miner (PTS)

[dga]

For those who don't feel like reading through a bunch of source code but find the algorithmic issues interesting, I've posted a little writeup on my blog about the basic problem and solution used in the GPU PTS miner:

Hi dga.
Your work is fantastic. But I do have a small request for the next build, and I would like to ask if it's possible: Could you implement the interactive mode like cudaminer. Your miner is already top, efficient and in low temperature for the card, but I can't use the computer anymore if I let it runs. Cudaminer has the interactive switch, so if you switch this on, you lose about 5-10% of hash, but you won't notice much about how your computer lags. I would be very happy with this.

Thanks dga.

Regards.

Yup, it's on the TODO.

hi. How to use cudapts to connect to ypool.net?

The latest build dropped my cm rate from ~1650 to ~1250 on a GTX 780.

Ok just released cudaPTSwin - Beeeeer - PTS GPU miner for Windows  -> https://bitsharestalk.org/index.php?topic=2311.0

Cheers!

earthbound,

got missing MSVCP110D.dll

Thx

Looking into that, apparently that means I didn't properly build it in "release" mode (so even installing the redisributable probably wouldn't fix it). . .

Gronk make dirty hack visual studio windows port compile and run. Gronk post compile and source code here.

Gronk not sure miner actually doing any pool work when run. GPU gears spin-spin, but no output to screen maybe? How make write on screen? Is doing any work? Maybe it work? Please test, advise. Gronk tax disabled for test. Mines at Gronk drink beeeeer mine. Want make mine anywhere. Not do that for now.

Thank!

with the new version it's look like im down 100c/m per gtx 295
each gpu in the gtx 295 was getting 340+ now it is only getting 290c/m

+1 to this - my GT210 dropped from 80c/m to 50c/m with the latest update.

That's no good. :(

Did you both let it run for a while before comparing the #s?  It can take an hour or two (particularly with slower cards) for the rate to become steady.  I'm going to add another "speed" metric that's a bit more relevant to quick benchmarking, but for now, c/m it is. :)

I'm surprised.  The changes I made shouldn't be large, and slower cards, if anything, should see almost no effect.

Yessir I did - normally let it run for ~2 hours to stabilize. :(

I can confirm too, dga.
I have test at least each card for 1 hour but the maximal rate drops at least 10% in comparison to your previous version. I don't check the memory consumption or temperature.

Well, let's not let the AMD folks win, shall we?

Obviously, they can keep cloning my software, but let's let the folks using the open version have some fun for a while longer.

I've committed another optimization to the repository.  My GTX690 is now getting about 1850 c/m - not a huge boost, but a little.

The more important thing about this commit is that it removes the dependency upon yasm, which I know was causing some folks a headache trying to compile it on Windows.  Let's see if this makes it easier to use the open source version instead of a who-knows-what-you're-getting closed clone. :-)

And - many thanks to the people who're running the miner with dev donations to me enabled.  I know you don't need to, and I appreciate it.  That, and the few direct donations I've received, are what's going to keep these improvements flowing.
