I also want to trade XPM on BTC-e, it definitely deserve to be on BTC-e.
But right now: PhenixEX is really great exchange where we can trade XPM! and their affiliate system is working smothly.
Thats why I have referral code in my signature...use it now and have lower fees forever.
Oh Fuck off, nobody is trading on phenixex I don't get why people bother anymore. |

Here's a benchmark i found:  The Coremark benchmark is not a floating point benchmark, it's main focus is read/write operations, integer operations, and control operations. Generally speaking the Epiphany coprocessor was designed to do floating point math very quickly. This test is probably not really a 100% good representation of it's ability of doing integer ops, due to it being biased by other external factors (read/write etc). The Epiphany 3 with 16 cores has a core mark of: 19478 and costs $99 The Intel Xeon Processor E5-2687W has a core mark of: 400116 and costs $1890 plus say another $400 for a computer build: ~$2290 20 Epiphany 3s would be about the same speed as that Xeon. and if you built that using their cluster kits, it would cost. ~2875. Granted you could probably build two or three computers with more total computing power and cheaper than using that insane Xeon, and probably get your costs down even further. Furthermore, unless you are a coder, you are going to have a bad time. You won't be able to just drop the primecoin miner into a paralella and hit go. There will need to be some code rewriting and optimizations done to the code, at very least you will have to significantly edit the make file to make it compile for the coprocessor. The Epiphany 4 with 64 cores that is not yet available on the other hand has a core mark of: 78748.80 but the price is unknown, as well as the availability. So right now, i would say No, i don't think the Parallela is a good bet. |

Comparing GFlops is meaningless here. FLOPS is FLoating-point Operations Per Second, and Primecoin uses integer arithmetic. So, even if the Phi is so much faster than X86 in floating point maths, it means nothing for Primecoin performance.
Yeah, you're right. This was the best i could come up with to compare integer maths between processors: http://speedtraq.com/?s=1Unfortunately the Phi isn't on here, but if we choose something that is relatively close to it: Intel(R) Xeon(R) CPU L7555 @ 1.87GHz, the result is: 88.478x Where as with the AMD FX(tm)-8350 Eight-Core Processor, the result is: 29.681x So even a Xeon that has more cores, and a higher clock speed than the Phi is still only 2.9x faster. Which means all it would take is three builds with those 8350s to outperform the Phi coprocessor. And now i think we are coming in cheaper than the Phi going with AMD, but it really depends on how much the rest of the builds cost (mobo, ram, hdd, psu, etc) |

Serious question, what are your thoughts on mining XPM with a Xeon Phi? Looks like those have a total of 57 cores @ 1.1 for a total of 62.7GHz of processing power. You can get 30GHz+ with an AMD Vishera for less than $200. I know the comparison isn't apples to apples, but I don't know why you'd spend that kind of money regardless. Yeah, looking at that, i don't think you can really compare things like that just on GHz alone. Benchmarks put the AMD Vishera FX8350 at around 35 - 40 GFLops. That Xeon Phi 3120 is ~1000 GFLops. So about 25 times faster. Unless i am thinking about this wrong. That would mean i would need 25 computer builds with those $200 processors in them to achieve the same performance. That is in no way cheaper ($5000 for the processors alone). |

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? Ahhhh so this is why it crashes on OSX 10.8, which ships with OpenCL 1.1 and there is no newer driver available. According to Wikipedia, when OS X 10.9 Mavericks ships this Fall, OpenCL 1.2 and OpenGL 4.1 will be built in. |

I'm hardly finding any blocks this week compared to the last one, unlucky or did something major change?
I found one since I started mining on my personally-owned server about 3 days ago. It's funny how you keep saying "personally-owned" over and over again. Almost like you're trying to hide the fact that you pwnd some box. |

Is there a way to use the cpu+gpu together?
Pretty sure that is what this miner does. Its just not well optimized yet. Give it a few months, now that the source is public, other people will make small changes and updates, and eventually it will be quite fast. There is no reason to believe that parallelization of prime sieving wouldn't speed things up, it's just very difficult to implement, and takes time. |

I wonder how long until someone who paid posts a real link to the miner.
http://cryptobro.com/ <--- the source is there, with an md5 hash. |

Anyone successfuly get this to run in OSX? i've gotten past all the other problems people have listed here but stuck on this: MTRLT ideas? Using device 0
OpenCL device 0........
Compiling kernel... this could take up to 2 minutes.
Error getting function data from server
2013-09-02 20:07:57 Error: Error building OpenCL program |

Okay I've sent the miner now! If you didn't get the miner, whine to me and I'll send it to you!
Hey thanks for the miner  I have some issues building it for XUbuntu. When I try to build bitcoin-libblkmaker I get this: red@red:~/Downloads/bitcoin-libblkmaker/bitcoin-libblkmaker$ make .deps/base58.Plo:1: *** multiple target patterns. Stop. Any ideas? Has anyone gotten past this one? i'm stuck here. |

Why pay, when it's free. Also, someone should really post an MD5 of the official EXE. |

All you people selling the miner are pathetic, you didn't even create it. Also it is already online for free http://cryptobro.comWATCH OUT THIS IS A VIRUS ...u dirty cunt !!! No it is not. i scanned it. you are a tool. |

All you people selling the miner are pathetic, you didn't even create it. Also it is already online for free http://cryptobro.comI'd agree its mad that they are trying to sell it if they haven't done anything that has improved on the original work. Personally think people should only sell it on if they have made an improvement (I spotted 1 being sold for 0.07 which included a required file which was omitted from the first release. Still seems mad, but amusing how quickly people dropped their selling price) Also just for reference the download from cryptobro.com doesn't actually work and for some reason he/she has renamed it RealPrime.zip where as everyone else has stuck with the original name - which makes me dubious as to its legitimacy -I had assumed as soon as the real one was released there would be others out there that suddenly sprung up claiming to be free but actually containing viruses. As it appears the download doesn't actually work from there I cant actually scan to verify or not. So folks do be cautious today is a perfect time for a nasty internet bad guy to try and infect XPM miners and steal your lovely coins! Huh? link worked fine for me, it's: http://cryptobro.com/reaperprime.zip |

Can one of the people who got the project directly from mrtlt please do an MD5 sum on the .exe file so that we can know for sure which is the real version, or if it is a virus or not.
Thanks.

Lol it's already been leaked anyway...

where can I download this gpu miner  If you want money you dont get money. Nowhere. No one will give you for free, because we paid for it. But you are smart guy.  Hahahaha, so from reading this thread, most people can't get it to compile, or run, or when they do it crashes almost immediately. The performance is said to be roughly equal the the performance of a CPU. Yet you are telling people to pay you for something you didn't even make. This is really really fucking funny. You should get a scammer tag for this kind of behaviour. |

I've decided on the last date to donate: >1 BTC donations before or on September 2nd will get the beta!
So people who donate 1 BTC won't be getting it on the 2nd? Or do you mean >= 1? Stupid question, just send 1.00000001 if you are really worried. wasting your time asking this over 0.00000001 BTC shows that you really have no concept of the value of BTC. |
