Bitcoin / Bitcoin Discussion / Balance 0.00

on: October 18, 2011, 11:54:08 AM

Today I sarted my bitcoin after a looon long time (3 months) and found out my balance is now 0.00, and no transaction history is present. this is weird, I had 0.00x bitcoins, so it's not a big deal at all hehehe BUT how is it possible, I mean, if someone took my btc, then at least I should have some transactions left. right? thanks! for your time!

Tried setting 1 gpu thread and 1 cpu thread and got a segmentation fault:

Works:
./minerd --gpu-threads 2 --url --pass --user

Segmentation fault:
./minerd -a sse2_64 -t 1 --gpu-threads 1 --url --pass --user

BTW... the help lists -g as a valid option to set gpu threads, but if you use -g 1 it says it's invalid.

Hi, I'm experimenting with m0mchil python gpu miner, jgarzik cpu miner, and your miner. I think I can reproduce this "bug", but I don't know why it happens, just that it can be reproduced in slower hardware. The thing is my CPU gets accepted solutions while my gpu doesn't. I get 4.8 Mhash on a Geforce 8600GT and 0.9 Mhash on one AMD X2 +4400 core using sse2_64 algorithm. So the math doesn't add up. GPU should be getting more accepted solutions. The difference is so big that the counter was 17 in the cpu and 0 in the gpu (I'm using deepcoin to track both workers). I restarted the gpu miner, got 3 shares in 20 minutes (it's a slow machine. I'm just experimenting) and then it stopped getting shares completely while the cpu just kept getting accepted solutions. I'm running jgarzik cpu miner (using 1 cpu core), and m0mchil gpu miner (using the gpu and one cpu core for some reason). I'm using Ubuntu 11.04 x64, 270 DEV drivers and NVidia CUDA 4.0. AMD64 X2 +4400 EE One last thing, I get segmentation faults whenever I try to use your miner. http://forum.bitcoin.org/index.php?topic=24311.msg303201#msg303201 I used this to compile it: Code: LD_LIBRARY_PATH="/usr/local/cuda/lib" CFLAGS="-O3 -Wall -msse2 -I/usr/local/cuda/include" ./configure make sudo make install I know it may be it's just not finding anything, but I really think we are talking about the same bug. How could the GPU find 3 shares in 15 minutes, and then just completely stop getting accepted solutions for 24 hours, while the cpu got 29 accepted solutions in the same time? I really don't know but it is strange because we are talking about pooled mining, if I were mining by my own I would have to way a few decades to find an accepted solution.

yeap. it's slow indeed. I'm getting 4800 khash/s using the geforce 8600GT, and 900 khash/s on the remaining free cpu core (AMD X2 4400 EE). I'm just experimenting with bit coins. Anyway I changed the python miner code to revert the latest git optimization and at least I got 3 shares so far (the counter was stuck at 0 after 16 hours of running). So I guess I'm going to wait to verify if the bug is fixed. My current share count is 22 for the cpu and 3(!!!) for the gpu

on: June 29, 2011, 08:09:35 PM

fixed! All I had to do was to rollback the last commit: https://github.com/m0mchil/poclbm/commit/3d43c4e4c2c476cf367822868202f02d168d6f3b It seems that the new code: #define Ma(x, y, z) amd_bytealign( (z^x), (y), (x) ) is not the same as the old code: #define Ma(x, y, z) amd_bytealign((y), (x \| z), (z & x)) I changed the code back to use the old one. Now my poclbm uses "amd_bytealign((y), (x \| z), (z & x))" , and the gpu started to get shares. Everything runs as it should Update My bad. it's not finding anything . It got 3 accepted solutions the first 15 minutes, and then it just stayed there.

I can't post in the original thread, so I will ask here: I'm running a CPU miner and a GPU miner in the same PC. CPU miner: 0.9 Mhash jgarzik-cpuminer (it is NOT the ckolivas version) using 1 cpu thread minerd -a sse2_64 -t 1 --url http://pit.deepbit.net:8332/ --user cpuworker --pass workerpass GPU Miner: 4.8Mhash poclbm using the other CPU thread and the GPU python poclbm.py -d 0 --host=pit.deepbit.net --port=8332 --user=gpuworker --pass=workerpass I already created a post about this, but I think I got it wrong. This is the right place to ask. My setup is: AMD64 X2 4400+ EE Geforce 8600GT Ubuntu 11.04 x64 Nvidia CUDA 4.0 The problem is that I'm getting shares in the CPU, one each hour, but I'm not getting shares on the GPU (which is 5 times faster) and it's strange, cause its constantly giving shares to the CPU worker, and the GPU worker hasn't found anything, they have been running for about 16 hours now. I checked in my account, and the cpu worker says 17 shares, but the GPU worker says 0, and they are both running without problems in my PC, no error messages present, they are both showing the hash rate and sometimes the long poll notification.

update:
I tried using new gpuminer implementation from ckolivas. but it's giving me a segmentation fault:

Hello everyone, I'm using old jgarzik miner (CPU only) to mine with 1 cpu thread and poclbm python miner to work on the GPU. I'm using deepbit. I've set up two workers, jgarzik works on CPU mining, and finds a share every hour (that's really slow! I know). the other worker uses the latest m0chil python gpu miner and it's using full GPU and 100% of one CPU core (cause the latest nvidia cude implementation) BUT IT DOESN'T FIND ANYTHING! I get 4.8 Mhash on a Geforce 8600GT and 0.9 Mhash on one AMD X2 +4400 core using sse2_64 algorithm. My problem: why does the cpu worker find a share every hour, and the gpu worker is not finding anything, even though it has 5 times the cpu power? Thanks in advance.
