Unable to add worker with debug level 5, 4, 3 about excavator

[nicehashdev]

We were unable to reproduce your issue by just setting debug console level. Could you also share your command file?

[nicehashdev]

Your issue looks like a crashed driver that needs system reboot. Have you tried that?

[nirvanaosc]

I did now. It still happens.

[nirvanaosc]

I will try to get a list with the commands to reproduce this issue.

[nirvanaosc]

Executing the following command reproduces the issue:

excavator.exe -na -d 5 -p 5000 -wp 6000 -wi 127.0.0.1 -c file.json

with file.json containing:
[
{"time":1,"commands":[
{"id":1,"method":"algorithm.add","params":["equihash","equihash.eu.nicehash.com:3357","34HKWdzLxWBduUfJE9JxaFhoXnfC6gmePG.testrig"]}
]},
{"time":2,"commands":[
{"id":1,"method":"worker.add","params":["0","1"]},
{"id":1,"method":"worker.add","params":["0","1"]},
{"id":1,"method":"worker.add","params":["0","2"]},
{"id":1,"method":"worker.add","params":["0","2"]},
{"id":1,"method":"worker.add","params":["0","3"]}
]}
]

I am using NVIDIA drivers 384.76

[nirvanaosc]

It works with debug level 0, 1, 2 and 6 (but 6 seems the same as 0)

[nicehashdev]

Can you try with some older driver version?

What happens if you add only certain device and not all?

[nicehashdev]

No response anymore, closing.

[nirvanaosc]

Sorry, I am away for one week and I don't have access to my hardware.
I will try once I am back and I will report back to you.

[nirvanaosc]

Hello,

I'm back and I tested what you suggested.
Drivers 378.78 (the oldest drivers I could get) behaves exactly the same. These drivers are 4 months old.
Also, I tried adding only one worker to the first device with the json file:

[
{"time":1,"commands":[
{"id":1,"method":"algorithm.add","params":["equihash","equihash.eu.nicehash.com:3357","34HKWdzLxWBduUfJE9JxaFhoXnfC6gmePG.testrig"]}
]},
{"time":2,"commands":[
{"id":1,"method":"worker.add","params":["0","0"]}
]}
]

and I got the error

[20:12:02][0x00001950][fatal] wrkr0-0 | CUDA error 'invalid argument' in func 'cuda_eq_run' line 2356

Using the command line

excavator.exe -na -d 5 -p 5000 -wp 6000 -wi 127.0.0.1 -c file.json

If you need anything else from me please let me know.
Regards.

Could you also share with us what kind of cards do you use?

[nirvanaosc]

This rig has 8x ASUS GTX 1080 Ti Founders Edition

[nicehashdev]

Let me make this clear, when you change -d 5 to -d 2 and NOTHING else, it works just fine?

[nirvanaosc]

That is correct.

[nicehashdev]

What happens if you unplug 7 cards and leave just 1 inside?

[nicehashdev]

And does it happen for all algorithms or only equihash?

[nirvanaosc]

It was happening the same with blake2s. I didn't try the others.

[nirvanaosc]

Let me try with just one card.

[nirvanaosc]

Yes, it happens the same with 1 GPU. This GPU is not using a riser.

[nicehashdev]

Got it now. Fixed in next ver.

[nirvanaosc]

That's good news. Glad to help.

[nicehashdev]

This has been fixed in latest version.
