RPC Miners (CPU/4way/CUDA/OpenCL)

[crazyates]

Thought about it (gdb) but in the end I gotta ask: is it worth it?

I mean (other than pure curiosity which drives me so far) is using this CUDA miner gonna bring me some gain in speed, so much that it would turn an Nvida card in something efficient for mining?

So you have an 460 and I suppose you have done some tests openCL vs Cuda with it...is there any significant improvement?   

Obv being optimized for your hardware will help, but it really depends on the number of cores you have, and at what speeds they're running at. A 460 has 336 cores, at 675MHz. The closest comparison I can come up with is a 5570, with 400 SPU at 650MHz.

The only improvement in cuda vs opencl is not having the miner use 100% cpu of 1 core. Which is the entire reason I updated the code for this one to support newer gpus. If there is any performance difference; It's insignificant at best.

No point then...

A 470 has 448 cores so that would be close to a 5670 perhaps?....still weak.
I can bring it with cgminer to 150MH/s and I was curious to see if CUDA would push that limit even higher...

Thanks

Hello everyone. I would like to know if there is still someone interested in trying to compile this in Linux.

I'm having trouble to compile in Ubuntu 10.04. I am preparing a little script in Bash based on previous posts so that others benefit from it as well, but I can't get pass the issue with nvcc (I'm using gcc and g++ version 4.4). I also attach the characteristics of my video card. Let me know if you need more information:

The error is this:

Code:

/usr/lib/gcc/x86_64-linux-gnu/4.4.3/../../../../lib/crt1.o: In function `_start':

collect2: ld returned 1 exit status

The script is this

Code:

#!/bin/bash

# Script to modify the source to build rpcminer with CUDA support

I have been using 1.3 for GPU_CompCap. I also tried with 1.2 with the same result

If someone can help me with the optimal parameters, that would be greatly appreciated :D

I might be interested out of curiosity but I no longer have a working Nvidia card. I fried mine while playing Amnesia.

[Bernd33-1]

Hi,

I try to work with remote miner server and remote miner client but with no success. Maybe one can help?

My PC with Internetconnection (IP=192.168.0.113) starts with:
rpcminer-cuda.exe -url=http://port80.btcguild.com:80 -user=USER -password=PASSWORD -threads=1 -aggression=8 -remoteserver -remotebindaddr=192.168.0.113 -remotepassword=banana -distributiontype=contributed

A second PC in my network (192.168.0.110) starts with:
rpcminer-opencl.exe -server=192.168.0.113 -password=banana -aggression=6

But the Client says always "Could nit retreive work from RPC Server. Curl return Value 7"

Maybe someone knews what I'm doing wrong?

Thangs, Bernd

HAHA Well, I hope we don't do the same thing with this one. Let me know if you come up with some ideas. I am willing to try...

[420]

is there potential to damage a card?

[slush]

Is this miner still in development? If so, there's one bug report: https://bitcointalk.org/index.php?topic=144016.0

[slush]

Many people reported problems while using RPCminer with Stratum proxy. I just released Stratum proxy 1.5.1 with workaround especially for RPCminer. If you have RPCminer and want to mine over Stratum, please use proxy with --old-target parameter and let me know if it fixed your issues!

[Clock Loop]

I have dual gtx460's watercooled & oclocked to 851mhz and they hash at about 145 Mhash/sec (70Mhash/sec each)
This is the norm for nvidia.
 

I use two rpcminer-cuda.exe instances like so:
-gpu=0 -gpugrid=320 -gputhreads=320 -aggression=7 -workrefreshms=1000
-gpu=1 -gpugrid=320 -gputhreads=320 -aggression=7 -workrefreshms=1000

Guiminer Messages about "lost connection" are normal, its from the pool servers reply time.  

Every server has different reply times, if your miner tries to query the server too soon, guiminer will say you have connection problems.
You need to find the refresh rate your pool allows and change -workrefreshms=XXXX to the servers limit.
Default for  -workrefreshms=4000


Most virus scanners and firewall programs hate "coin" miners and call them viruses, so make sure your virus scanner and firewall allow rpcminer-cuda.exe, and guiminer.

I use p2pool as my pool server.
https://bitcointalk.org/index.php?topic=18313.0

DO NOT USE rpcminer-mod-cuda.exe
This MOD also uses up all of 1 cpu, so i think its using the cpu to do hash also, perhaps tricking users into thinking its better than original.  It uses all cpu, and no hashes are accepted in GUIMINER, even tho it says its hashing, and p2pool says almost all are DOA...
DO NOT USE THIS MOD-->hxxps://github.com/cdmackie/rpcminer-mod/tree/master/bin
 USE ORIGINAL RPCMINER

Original RPCMINER: https://bitcointalk.org/index.php?topic=2444.0

If your RPCMINER program uses 100% of any cpu, and GUIminer shows 0(0) under "Accepted"
 (if you are only doing gpu mining) then you have the modified broken rpcminer-cuda.

I'm attempting to use NVCC to get rid of the Unable to Load CUDA module error. I'm getting this after I run the command to compile.

LIBCMT.lib(crt0.obj) : error LNK2019: unresolved external symbol _main reference
d in function ___tmainCRTStartup
a.exe : fatal error LNK1120: 1 unresolved externals


Anyone able to help?

[uMMcQxCWELNzkt]

Noob question? How do I set this up, the readme.txt does not have any instructions, I have a NVidia GPU. So far I have copied the rar files into a folder in the program files. When I start up the rcpminer-cuda.exe I get this message...


If I remember correctly I would need to join a pool or something?

[Krako]

Hi
I trying to use the rpcminer.cuda.exe with guiminer (geforce gtx660)

Client will start 1 miner threads
Work will be refreshed every 4000 ms
1 CUDA GPU devices found
Setting CUDA device to first device found
Loading module bitcoinminercuda_11.cubin
Unable to load CUDA module

I get the above error but few pages back I found this answer

You need to compile the .cu file targeting the 1.1, 1.2, and 2.0 CUDA architecture, and give the resulting cubin the appropriate name, and place it in the working directory before you start the miner.

Please can some one teachme how to doing this? I am absolutely ignorant about and I have no Idea what is this and how to make it work.

Thanks a lot in advance

[Aggrophobia]

is anyone able to compile the cudafiles with cuda 5.0 for windows 7 x64?

[milazi]

windows

[Stoneysilence]

I tried to download the Windows Binaries and got a warning from ESET NOD32 that it was a virus they coined BitcoinMiner.M

[420]

with a cuda mod miner I get 185Khash with litecoin on GTX 680

[Eli0t]

for anyone wondering if this app will give you a faster hash rate than newer CUDA miners the answer is no

after some tweaking for best performance i was able to get the same hash rate (maybe even 1% less) as i get by default with ufasoft Coins CUDA implementation and there i get a much better readout and stratum support into the bargain.

560ti(no OC) ~83 MH/s with -aggression=9 -gpugrid=128 -gputhreads=384

[Tritonio]

Avira started detecting the rcpminer-cpu.exe as a Security or Private Risk (SPR/BitCoin.djh.1). Also if you search the file's hash on google you'll find that it's known as winvnc86.exe and wininiit.exe. I suppose someone used it in a botnet or other trojan?
