[XPM] Working on a GPU miner for Primecoin

[mtrlt]

If you have something against it, please say so.

Well releasing the CPU miner to the public could hopefully lead to some more pools, right?

[LZ]

Donators took the risk and expected the miner today. But you're right.
It's only your choice to release the CPU version publicly or privately.
I just thought that it would be better to give it to donators first...

[mtrlt]

It would be a bit weird for me to send a CPU miner when I've promised a GPU miner.

It would be a good bonus:)

[LZ]

Here's only one thing. The public CPU miner could potentially reduce donators' income.

Why not release the CPU miner to the public? The donations were for a GPU miner, which will still be in a closed beta when it's ready.

I've donated for the GPU miner, and I don't see any problems with this.

It would be nice to test the CPU miner first to solve any problems associated with the new architecture.

how much need to donate to see cpu miner?)) and how to use miner if primecoin wallet not support external miner(cpu/gpu)?

@mtrlt How would you deal with refunds if you were unable to deliver a GPU miner at all?

A Refund for donations? Really? Do you ask for refunds when the cure for cancer hasn't been discovered but you donated? DONATED is the key word here.
C'mon people...be reasonable...let the guy do the work and not wast his time answering dumb questions!

The key word he used is "donation". This basically means that he can run away with your coins and you can't do anything about it.

Got it!  Nice to know. It could be my next buissnes then. I promise something, then say I cant deliver and thank you all for donations and support 

Every day I learn something new!


I really hope that will not be the case here of course...

Not delivering it and not meeting the deadline are different things. Just give him some time. I'm sure he is hard at work. Wink

I'm a total noob at this & OpenCL but I guess if you CPU make the sieving you would have to move it to the GPU memory in an efficient (DMA-style) way, which is not trivial, compared to (system) RAM. Using the GPU to sieve would probably ease the task.

Good luck, will consider a donation if you keep us updated

You could probably argue that he promised something in return for the donations and didn't deliver but still this is not the case for now so give him time.

[Pmalek]

I dont have problem with prolonging a deadline! I am just in doubt about the final product, are we gonna see it at all...

Donation for GPU miner is a high risk, high return business.

Okay, progress report. As I said earlier, the CPU miner works now. However, my initial plan of doing the sieve work on the CPU and the expensive primality tests on the GPU didn't work. I've come up with another plan but it will take a couple days to implement.

The plan is to do the sieving on the GPU. The sieving is still something I don't fully understand, but I'm sure I can do it by studying the code meticulously.

mtrlt,

If you need help understand sieving better, you should look up some old distributed computing projects such as RieselSieve or SeventeenorBust. The SeventeenorBust forums might hold some key answers for you. I also suggest if you need some help understanding stuff to check out the Free-DC.org forums and specifically seek out a member named "Bok". I believe that forum and that user specifically could help you out substantially with any questions you may have. (:
