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

[pyromaniac]

I can't turn the fermat test off because then it crashes straight on start and I get fraction assserts error.

Same problem. Any suggestions about how can I fix it?

I can't turn the fermat test off because then it crashes straight on start and I get fraction assserts error.
I have gotten the program to work for roughly 30-45 sec then it crashes.
I have 2x7990 and I am running all 4 cores.
I have the latest drivers and I run on windows 7 64 bits.
I have the following settings

host 127.0.0.1
port 9332
user username
pass password

protocol primecoin

worksize 256
aggression 16
sievepercentage 10
sievesize 1000000

primecoin_address AbJSsYd5cnj2MxmBEHxtWo8kwpt7qA77xM
debug false
opencldebug false
cpu_mining_threads 4
use_gpu true
use_gpu_fermat_test true
getwork_rate 1000

Any suggestions on how to fix it?
//DeaDTerra

Set the "cpu_mining_threads" to 8 and the "getwork rate" to 4000

OS? 32-bit or 64-bit? It might be that 64-bit is broken right now.

Okay, I will try that out

I am using 64 bits, so I think it might be a problem with that.

It started and worked for about 10 seconds then it crashed.

Both of my rigs are using win x64, and it works, so probably not the x64 is the problem. Maybe its gpu specific. Both of my rigs are cypress based, but you are using tahiti gpus.

I should have been more specific: I think there's a problem if you compile it yourself on 64-bit Linux. The supplied Windows binary is 32-bit.

Ubuntu 12.04 + x86_64, AMD GPUs -- works for me.  No blocks yet, but it looks busy and the numbers are sane.

DeaDTerra also uses win7 x64

Ok, so the problem isn't there.. I'm mining on win7 x64 just fine.

[ivanlabrie]

I'm having trouble compiling from windows... I'll install Ubuntu to try it.

64-bit.

Somebody, please, make a working 64 bit binary file.

I have the same problems and I am on windows 7 64 bits, with a 3770k Intel CPU and 2x 7990 GPUs.

For all the people with crashes, dll issues aside, I found that deleting the generated .bin files, setting "save_binaries no" in reaper.conf and worksize to 256 in primecoin.conf reduces crashes to a minimum, at least on my system.

YMMV

Both. Windows on first PC and Ubuntu 13.04 on second.

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.

So people with Nvidia cards are just SOL until 10.9 comes out?

I gave it a try, didn't lead to any improvements unfortunately.

DeaDTerra, could you try with:

Code:

cpu_mining_threads 1
debug true
opencldebug true

and put the entire output to pastebin.com?
