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

[tbly13]

I feel like some of the folks here owe mtrlt some apologies for getting their pitchforks out...

lol

Guys, anyone please help to figure out the reasons of this

Its only detecting one device and it's not using the device it is detecting. I'd say drivers.

In reaper.conf:

Delete: Device 1

paulthetafy/entz I got that fixed..

edit base58.c in the libblkmaker dir and add these middle lines:

perfect, thanks!

reaper.conf
try:

device 0

tried - no effect

Okay, so the way I got it working is kinda weird - first, to generate the kernel modules,  I had to disable the gpu fermet test. then reaper crashes with 'fractional assert'. Next, I changed it back to enable the gpu fermet test. Then reaper runs without issue. Aggression does not seem to affect how aggressive the miner is, however, so my computer is really not usable while mining. speed does not seem to be much better - perhaps ~2x faster than on CPU alone. I suppose a lot of optimization is coming and various fixes for the weirdness to get it working on all platforms. It also only seems to detect one GPU, unless it's seeing both GPU's as a single OpenCL device? Two kernels appear to get generated, so I'm really not sure what's going on.

In reaper.conf:

Delete: Device 1

tried - no effect

strangely, removing device from conf changed nothing
does 'reaper.exe' read the confs at all?

You mean Gandalf?
A f*ckin wizard.

[rgzen]

Who know what I must put in primecoin_address???
If I put anything different to mu1DxMiRUgzjNrVyVeHeRhqDm3XVK12SK2 it does not work...
But it seems working well if I leave it unchanged, curious because all addresses I generate begins with A key.
WHAT IS mu1DxMiRUgzjNrVyVeHeRhqDm3XVK12SK2 ?

Well reaper says he's coming 1500 times a second. Apparently not a wizard in bed.

You need to modify the blkmaker source to allow XPM addresses to be added.  I dont have the source handy now (ipad) but it was talked about earlier in this thread.  there is a case statement where you need to add cases for the XPM addresses, i remember the cases were 23 and 83, just cant remember what file   just search or ask in #mxcnow or #primecoin

[paulthetafy]

Has anyone found a block yet?  Or even worked out how fast is it?  I haven't mined a block and in my testing it is a little slower with 2 x 7950 than just running HP10 on the CPU on the same machine.  I'm hoping I have some config wrong somewhere, but I've tried everything I can think of.  I'm NOT running the fermat test on the GPU as that is slower again.

finally got it to work - thanks to iANDROID, reb0rn21, k0vic for your help!
was editing the wrong confs initially 

BUT! now it says

the heck is block template ?

Getting an app crash after a few seconds of starting mining...don't get it.

Any clues?

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?

Same here on arch...
Any solution?

Just solved. Only have to add this text into CMakeLists.txt:

Code:

FIND_LIBRARY( OPENCL_LIBRARY NAMES OpenCL PATH
        $ENV{OPENCL_LIB_DIR} 
        $ENV{HOME}/.local/lib
        /usr/lib
        /usr/lib64
        /usr/local/lib
        /usr/local/cuda/lib64
        /usr/local/cuda/lib 
)

test it paulthetafy, let we see if works for you too...

Okay this didnt work for me.  in IRC mtrlt said that I need libOpenCL.a, which I don't have.  There is some suggestion that the latest AMDAPP doesn't come with the .a, only the .so.  If anyone has libOpenCL.a please can you PM me or put it up somewhere so I can DL it?

Same problem.  I get the OPENCL_LIBRARY-NOTFOUND message.  Adding the text above to my CMakeLists.txt file did not resolve the problem.  I've searched Google for hints on how to get the libOpenCL.a file, but it must be a well-protected secret because I can't find any useful directions.  Any luck yet?
