win7 64 amd13.12
280x 3100, but 290 only 2800?

I released a fast OpenCL PTS-miner for AMD GPUs. The performance is 3100+ c/m on a R9 280X and 1300+ c/m on a 7870, so that this seems to be the fastest released miner. Binaries are available for Windows and 64bit-Linux.
DOWNLOAD v0.1.x: https://www.dropbox.com/sh/d5qvec5kxlug1bm/FR3Y_78Eag connects to the beeeeer.org pool, which has 2.5% pool fees. The developer fees for this version are 7/367 ~ 1.9%.
DOWNLOAD v0.2.x: https://www.dropbox.com/sh/1ioh00043hqbsbk/wTptW3dr22 connects to the ypool.net pool, which has 5% pool fees. The developer fees for this version are 2.5% to make smaller pools more attractive. The developer fees are automatically transferred by ypool.net to the developer so the user's miner does not need to reconnect to support the developer.

UPDATE 10: version v0.2 of the miner is released, which supports the pool on ypool.net. If you want to connect to beeeeer.org you should use v.0.1.2. The miner does NOT support the 1GH-pool yet because the pool does not implement the latest xpt-protocol but 1GH-pool support is still planned. EDIT There was a typo in the README. The usage of v0.2 is <exe-name> -u <username>.<worker> -p <pass> -t <GPU DeviceID list>

UPDATE 12: I released a new version with large performance improvements. The syntax of the command line options of v0.1.x has changed and one has to specify the device IDs like in v0.2.x (see README). Furthermore, the command line option -a was introduced to select an algorithm. I guess that -a 0 or -a 2 should be fastest on R9 290(X) and -a 1 or -a 3 should be best for non-R9 290(X) cards.

known issues: The miner does not run if the installed Catalyst driver is too old. Multi-GPU support works for most users but sometimes the miner won't work if there are different cards installed. Then you have to run an instance of the miner on each card. The miner is not optimized to run on 5000 and 6000 series GPUs and needs about 1.2GB free GPU RAM.

NOTE 1: When you post errors I appreciate some information about the operating system (Windows or Linux / 32bit or 64bit is sufficient) and the used Catalyst driver. Furthermore you should suppress the section between the stars of the output of the miner excluding the miner version (at the moment it hasn't any relevance but it will become important in the future).

NOTE 2: Please make sure that you are not using an outdated Catalyst version and read the README.


I would be grateful for donations to speed up the development of a version for Nvidia GPUs and 1GH-pool support:

Any plan to release windows bineary file?

Following up on yvg1900's release of yam, I figured I'd improve the state of the art of the open source versions a bit:

https://github.com/dave-andersen/ptsminer

I haven't made it build yet on windows (it just needs to compile the avx2 assembly code - should be straightforward if someone wants to clue me in on how to appropriately invoke gcc there), but it should work on other platforms.  As a warning, I've only really tried it on avx2, since I'm a fan of Haswell.  THIS SOFTWARE SHOULD BE CONSIDERED A BETA QUALITY RELEASE.  At best. 

As with my GPU release, this one is based very directly on ptsminer, so it's tied to beeeeer for the moment.  I plan to fix that and let it be used with other pools in the near future, but that's going to take some dev work.  sigh.

There's a lot of optimization to be done, but this gets the basics as far as memory subsystem optimization, and bridges a lot of the gap between the old OSS version and yam M7i.  I haven't tried out M7j, mind you -- it's probably a bit faster still, but this release should bridge the gap considerably.

It incorporates the same optional, extendible 1% dev fee that the gpu miner does.  Prior ptsminer devs, if you feel like you should be in the list, please PM me and I'll get you added!

With gratitude to FreeTrade for the donation that kept me interested in hacking on and releasing this stuff, and to yvg1900 for some very engaging unofficial competition. *grin*

No, ip is fixed. I restart miner can connect.

This means that the miner isn't able to connect to the server. That's a different problem. It could be a boost related problem, i.e. boost::asio::connect somehow fails. Did your IP change before that happens? I'm trying to fix it

Suggest you give version number on zip file. Otherwise no one knows which version
is using.

We had a huge number of getwork connections that started to cause other connections to be closed. This is mitigated now, but we recommend to upgrade getwork miner to anyone who still runs it.

first, after startup, it shows
LOOP UNROLL: pragma unroll (line 160)
    Unrolled as requested!
LOOP UNROLL: pragma unroll (line 112)
    Unrolled as requested!
...............
but can still work

second, I have 2 280x, it can't start 2 card in one instance, must run 2 instance.

third, after a while, maybe minutes or hours, it seems meet some abnormal sharetarget, and stop find share anymore(from gpu monitor, gpu sitll 100% load)

4th, If there's no network connection while starting, it will crash.

Could just be the nature of PTS mining but Ubuntu build netted me 8 blocks to 1 in Windows version.  Is the 35 seconds mining for you getting messed up and all blocks go to developer?  Still getting this on start up in Windows.

No, that is because of bad pool luck while you were mining in windows. beeeeer.org is a small pool with only a few generated blocks per day (mostly less than 10), but is has low fees (2.5%). Your windows output seems normal.


@rots: did you encounter any problems or does the miner work well?

quite astonished that
6850 800cpm !!!
270x 650cpm
280x 1100cpm

6850 seems drugged!

Same error here... 
win7_x64, 2x R9280
Hope you can fix this! 

Fixed the new implementation so it works on AMD. All that had " error: expression must have pointer-to-struct-or-union type" type errors, please download the new version (build6), or simply update the sha512vectorized.cl file in your already downloaded build5.

Thanks to all for the bug reports and for the patience.
