Hi Vasudev

 There is nothing we can do, I am afraid. You have to speak to your cluster administrator, so that they setup things correctly on the cluster.

Cheers

Dear moises,

I am using a GPU cluster, and i do not have any  admin rights to install CUDA driver.

Thanks

Dev, please check the CUDA toolkit installation log files. Check the driver was installed correctly without errors.
Also, please check that the node where you are running nvidia-smi has a GPU and is correctly installed. 
If error persists, I would remove all the previous CUDA drivers installed, and start a clean installation.

You will need to reinstall the driver.
I would install CUDA toolkit, the driver will be installed as part of it:

I would use nvidia-smi to check what GPU(s) the node has, and if they are free.

Dear Moises,

Yes, same error persists, although i am running the bedpostx_gpu on GPU cluster.I dont know the reason for this problem

Thanks

I can see exactly the same error: no GPU

Dear moises,

I have reworked on analysis, but still , i am unsure if the file size that  i am getting is accurate


Kindly check the results of  this subject.

Thank you

Hi Vasudev,
in your log files you can find this message:
cuda error at CUDA/init_gpu.cu:17. no CUDA-capable device is detected

So no GPU was found (or free) on that node

Dear all,

After i run bedpostx_gpu analysis, i am confused if the size of the files merged_th1samples,merged_th2samples  etc should be larger than what i am getting, could you please check the sample output ( https://www.dropbox.com/s/uby0erm3ntk14s4/KON11.bedpostX.zip?dl=0 ) and let me know, if you think bedpostx_gpu was accurately run .

Thanks
Vasudev
