Hi, I didn't face such error yet. Let me think what can be a reason.
from daggergpuminer.
jonano614, a couple of more observations. When I increased the number of used devices (Ex, -d 4 or -d 8),
- the CPU consumption gets extremely high (looks like the GPU miner is also doing CPU mining). Would it be possible for you to disable CPU mining in the GPU miner?)
- the MH/s for each card is going down significantly. Fro ex, when I use only 2 GPUs (-d 2), I get about 1100MH/s for each card. And when I use 3 GPUs (-d 3), I get about 700-800 MH/s. Not sure if this is due to the high CPU utilization or due to something else.
Please let me know if you need any additional info. I noticed that there is no logging, or else I would have sent you the log file. Thanks!

Hi.
- No, GPU-miner does not use CPU-mining. There are some tasks for CPU, but they must not consume much CPU time. It is a bug.
- Probably the problem is related to previous, GPU might be waiting when CPU completes some work.
I don't have such problem. Probably because I have only one GPU with fairly low performance (240 MH/s). So it can take some time to find out the reason of the issue.

YesοΌ I use 6 gpus, so the miner take 100% cpu.

jonano614, one other comment. On my 8 GPU mining rig, the CPU I have is an Intel pentium processo, which is less expensive and has low capacity. This may be one of the reason for hitting 99% CPU limit.
I have also one more laptop that has Intel HD Graphics 3000 which has Intel core i5, which is quite fast. In one of the posts I see that you have a miner for Intel. If you can share with me the miner for the Intel graphics card, I can test it on my laptop and see if I observe the same issue.
Thanks!
from daggergpuminer.
Probably Intel HD Graphics 3000 is not supported. I've tested it only on Intel HD Graphics 4600. Try "-list-devices -G"
Regarding error "clCreateContext: CL_OUT_OF_RESOURCES": as I undestand you try to run different instances of miner. I don't think it is a good idea, but probably it can work. But "-d N" parameter always uses first N devices. Try "-opencl-device 0 1 2" and "-opencl-devices 3 4 5".

Jonano, did you get a chance to look into the CPU resource issue. Any plans to release an updated miner?
from daggergpuminer.
Hi. I tryed to solve the problem, but unfortunately I didn't manage to fix that bug yet.
from daggergpuminer.
I also get the CL_OUT_OF_RESOURCES if I attempt to run the gpu miner on 3+ cards (interestingly, when I was at only 3 cards, I could run it on all 3, but now that I have 4 cards, it fails above 2). Currently, I work around it by having a separate xdag account and directory instance, and in each session, I mine against two of the cards (against separate accounts and storage directories to ensure no write conflicts with shares). However, I'm not sure why I get CL_OUT_OF_RESOURCES if I run against 3 or 4 devices in the same window (using -opencl-devices 0 1 2 or 0 1 2 3 (and I tested various permutations, but that had no effect)). I have an i7 5930k CPU and with two cards, its usage is around 40%, so I'm definitely not tapped out on the CPU. With the 4 cards in two instances, usage is around 50%.

New version 0.2.0 resolves this for me. π
from daggergpuminer.
I'm glad to hear that. Probably one improvement helped.
from daggergpuminer.
Sykoboy. I've released v0.2.3 yesterday. Could you please look at it. Probably it can help you.
from daggergpuminer.
Hi Jonano, thank you. I will switch to the new version and will let you know after I run it for a day.
from daggergpuminer.
Jonano, I have been running the new version 0.2.3 on my rig that has 2 GPUs. I do see this error. I did not get this error on earlier version 0.2.0.

Ok, I will try to find information what can lead to that error. By the way, since main coin dev left the project it is hard to find time now for miner...
from daggergpuminer.
Jonano, one update on that out of resources error. I think it has to do with loose cable on the 1080 card. I re-plugged all the cables and kicked off the miner and don't see the error. Mostly, the error may be due to loose cable. I will let you know in case I see it agian.
BTW, you have done some good work on this miner. I would like to send you some XDAG that I mined, but its not trading for much. I will send you little in ETH. Please post your ETH address.
from daggergpuminer.
Hi. Thank you 0x2d1044fe7eaf1e1d19eae70878862509f54bba8d
from daggergpuminer.
Jonano, just sent you little ETH. You should be able to see in your account. Thanks!
from daggergpuminer.
Jonano, the .25 ETH I sent got confirmed. But, I noticed something odd. As soon as the funds came to your account, they got moved to some other address. I am not sure whats going on. Something does not look right.

Anyways, not sure if we should talk about this in this particular thread. I will ping you on telegram tomorrow.
from daggergpuminer.
Thank you! It is very much!
The address is on exchange, so do not worry.
from daggergpuminer.
Cool, good to hear. Thanks again and keep up the great work.
