[XPM] Working on a GPU miner for Primecoin, new thread :)

[Hix]

I hope this GPU miner will not work, and the primecoin will stay only on CPU...

The error messages and crashing on my system was because i didnt have the primecoin client mining before running reaper.

[usahero]

Crashes 5 sec into mining:

VS 2012 debugger reports:

Unhandled exception at 0x0042621A in reaper.exe: 0xC0000095: Integer overflow.

[Pmalek]

Yep it crashes after 10sec. Someone post your reaper and prime conf file if it is working for you...

It writes invalid n % and goes on writing that million times...
After that it says fermat = 0 gandalf = 2323 ( or something)
Is that normal?

After that it crashes...

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

[usahero]

Decreasing sievesize increases working time from ~5 sec to 15-20 sec before crash

Oh. Freaking winrar made a rar file and just named it zip.. Fixed now. Please redownload.

Here is mine, as long as i have setgenerate true in the primecoin client running it stops crashing, not sure if its mining or not though??.

okay that sorted it.  Still getting CMake Error: Could not create named generator MSYS Makefiles

[Fablio2]

Am I mining?

[usahero]

setgenerate true makes my reaper not mine anything. 0 fermats 0 gandalfs. While if setgenerate remains false, it calculates (153k Total), but then crashes.

[jammertr]

same here, crashes after 10 secs

[mtrlt]

Hmm. Open cmake-linux.sh and change every mention of "MSYS Makefiles" to "Unix Makefiles".

[YipYip]

Set it to 8 threads

and

device 0
device 1
device 2
device 3

ANd its now mining ...YAY!!!

mrlt does the device x come into play or is it just the threads or do we need both ?

[YipYip]

Is this all good ??

[lonesoul]

Loving the piccys of the working miner (or what i assume to be a working miner ;-) )

Was the name Gandalf's a mathematical term i dont know about or was it just a name that was chosen for them particular result?

if its one that was just chosen thats fun ^.^ (Im a fan of The Hobbit/LOTR etc) if its a math name already for some reason i think thats even cooler!

lol looking forward to getting my hands on the miner :-) 7 GPUs waiting to start chewing through some numbers (well im keeping them happy with other coins at the moment but they really want those XPMs ^.^ {they were telling me last night in my sleep..... What?? other people dont speak to their GPUs? what are you mad or something! }





Quick question for YipYip, how long after you started the miner did you take the picture?   also are the results displayed Hourly numbers or total numbers so far? If its hourly numbers it looks like your current setup is equivalent to my 4 Core Xeon E5606 Server machine.  (Which is great in my option lol i want to get 7 more of them on the go with my GPUs!)

Set it to 8 threads

and

device 1
device 2
device 3

Are you using stratum proxy? What is your Primecoin and Reaper conf ??

What mean  log lines like this:

I assume this EulerLagrangeLifchitzPrimalityTest() shouln't appear so often?

Guys I'm trying to compile this on ubuntu and getting "asking for OpenCL = OPENCL_LIBRARY-NOTFOUND"

I have opencl installed and $AMDAPPSDKROOT defined.  Any ideas?
