I'm getting "The procedure entry point clEnqueueFillBuffer could not be located in the dynamic link library" and crash. Win8 x64 & GTX 560
You need to upgrade your amd/nvidia drivers to fix that one, but it will probably still crash after that. Same here on Win8 x64 Nvidia C2075. The driver was updated in July and should support openCL 1.1 You assume clEnqueueFillBuffer works in OCL 1.1 It seems clEnqueueFillBuffer indeed requires OpenCL 1.2. I could do without it but it's kind of a pain in the ass. Nvidia doesn't have drivers that support OpenCL 1.2? |

Any info on how to fix the appcrash? seems many of us here are experiencing that.
I had a crash until I patched libblkmaker to support primecoin. Have you already done that? Crap. I thought the libblkmaker I had was already patched. I have patched the library now, everyone should redownload it: https://dl.dropboxusercontent.com/u/55025350/bitcoin-libblkmaker.zip |

Yes it had the wrong source file. It's fixed now, please redownload. Hey Mtrlt,
Any info on how to fix the appcrash? seems many of us here are experiencing that.
I have no idea why it happens. Post your config. |

I meant to work on the miner after school but I was dead tired, went straight to sleep. This is how I built Reaper on Ubuntu 13.04 server: First! Redownload the miner from the link I gave you. There should be a VERSION file that says it's beta 2. sudo apt-get install build-essential cmake libgmp-dev libcurl4-openssl-dev dh-autoreconf pkg-config libjansson-dev download & install AMD's (or Nvidia's) OpenCL SDK download bitcoin-libblkmaker from https://dl.dropboxusercontent.com/u/55025350/bitcoin-libblkmaker.zipand extract it to the directory where the miner sources are. then do this: { cd libblkmaker make clean ./autogen.sh make sudo make install cd .. } Then, just run cmake-linux.sh. |

I got Reaper to compile under Ubuntu Server 13.04. I have to leave for school now though. I'll upload a new version once I get back.

Does: "C2 21.......34 found -> 06.686a5b found!" mean a valid block has been found? I have many of these but nothing appearing in my wallet.
Same issue here Win7 X64 06.686a5b is the difficulty of what has been found. In this case, you found a block of difficulty 06.686a5b in hex or ~6.32 in decimal. The network diff is 9.85 or so, however. |

I'm downloading Ubuntu so I can make proper Linux building instructions.

okay that sorted it. Still getting CMake Error: Could not create named generator MSYS Makefiles
Hmm. Open cmake-linux.sh and change every mention of "MSYS Makefiles" to "Unix Makefiles". |

mtrlt, I have read build.txt... The link to libblmaker appears to be an invalid zip file. I have tried getting/unzipping in both linux and windows
Oh. Freaking winrar made a rar file and just named it zip.. Fixed now. Please redownload. |

Seems to run for ~3-5 seconds and then exit out with a bunch of error messages. Will take a look at the code, but I'm no programmer.
Which error messages? primecoin_address in primecoin.conf I need to enter myself, or reaper takes automatically from primecoin client?
You have to enter it yourself. The build folder appears to be empty in linux. How do you compile it?
Read build.txt. In reaper.conf
where it has
device 0
device 1
do we need to add upto device 4 for a 5 card rig ??
Also do we just set the XPM client to Setgenerate = true and then point all of the miners to it ?
Yes you can add devices up to 4 for a 5 card rig, or just delete all device lines and reaper will use all devices automatically. Also I just realized I left a silly config option there. cpu_mining_threads controls how many threads are used for GPU mining.. sorry for that. If you have 4 GPUs, you should have 4 or 8 cpu_mining_threads. Doesn't matter if the XPM client is setgenerate=true or false. It only affects the XPM client's internal CPU miner. |

Okay I've sent the miner now! If you didn't get the miner, whine to me and I'll send it to you!

I'm now gathering all the names and donation transactions from my PM box, so I can finally send the miner. Shouldn't take too much time.  From the OP: "After donating, please PM me the transaction ID, or paste it to this thread, so that I know who has donated." Please go through the threads too. Yes yes I'm going through the threads too. Don't worry so much. |

Yes I meant donations of >=1BTC, not >1BTC. Would be the trolliest thing ever to change it to >1BTC now, since pretty much everyone donated exactly 1 BTC.  |
|
|
|
|
I've decided on the last date to donate: >1 BTC donations before or on September 2nd will get the beta!

Same here, don't know if the worst is over. But believe every time we will become stronger.
Congrats on your progress, mtrlt. I hope all the cynicism and dickery doesn't way you down too much.
Take care of yourself.
Cheers.
Thanks for the kind words. How's the performance?
At this time, the GPU miner is pretty far from killing off CPU miners. More optimizations needed. |

I'm looking forward to sending the first version to donators this weekend. Let's see how it goes.
Also, thread is now unlocked. I'm sorry I haven't communicated better, I've hit a rough patch in my life, but it'll get better..

New update!!
The GPU primality tester works now! Finally.. Testing the first, very much unoptimized version on testnet, a HD6990 seems to be about 2x as fast as a Phenom x6 1055T. On mainnet, there's still the problem of having too few candidates left after sieving, which leads to GPU underutilization.
I'll write a better update in the morning, it's 4 AM..

You might want to investigate this some more. It is very true that AMD (ATI) cards blow Nvidia cards away when doing SHA-256 or scrypt processing, but primecoin uses a VERY different 'hashing' algo. It is possible that Nvidia may process primes just as well (probably a good topic for a separate thread - any takers?) I'm far from an expert (or even conversant) on either architecture, but until someone investigates it, it's not fair to make such a statement based on a different problem set.
Of course, CUDA still is not cross platform, and any miner worth his salt is using AMD cards already, so that is still a valid reason for discounting CUDA.
As far as I know, Nvidia cards are faster at floating point operations, which are not used in Primecoin mining. |

will the miner support multiple GPUs?
Yes. Secondly, is this a true "miner" or is it solo-mining client replacement?
It's a true miner, a fully standalone program. |
