Ubuntu GTX 660 GPU 0: Invalid Argument

[Sesh360]

Getting this error when running the miner.

Recommended Config looks valid with 32 threads and 15 blocks, but fails with above error.

If I set it to 1 thread and 1 block it runs without the listed error.

CMake . DCUDA_ARCH=30

Can't seem to figure out what the issue is.

Thanks in advanced.

Please poat the suggested config. How much memory has your gpu. Try to use the autosuggested config und reduce the number of threads step by step by two.

GPU Memory: 3 GB

This is the suggested config:

{"index" : 0, "threads" : 32, "blocks" : 15, "bfactor" : 0, "bsleep" : 0, "affine_to_cpu" : false,},

I stepped the threads down and it still fails with the same message.

I am not entirely sure, but my GTX 660 TI was not supported (even I have compiled directly for it).

But try the following: remove the comma behind false and behind } .

The same binary runs like charm with newer cards (1060)

Bfactor 0 and bsleep 0 looks wrong.. try bsleep 8 and bfactor 15

@sheepchen

Removed commas - same error

Changed bfactor and bsleep - same thing.

I should mention that I am running a server version of Ubuntu 16.04.3 LTS. So my assumption is that the bsleep and bfactor should be 0?

[psychocrypt]

Yes bfactor on linux can be zero. You could try to compile for all architectures. Cleanup all temporary files qnd run cmake without setting CUDA_ARCH. The compile will take a few minutes.

Thanks for your help. Cleaned everything out and git cloned fresh.

Ran CMake . -DCUDA-ARCH=30 and Make Install with the config listed prior.

For some reason this time it worked correctly. 263.9 H/s.

Thanks again and enjoy your weekend!
