GPU/CUDA Installation Not Detected

[SASO Dupont]

Hello,

I am getting this error when running Hiccups. I have already installed CUDA 7.5 on my computer but still getting this error. Any suggestions to fix that?


Thank you,

[Neva Durand]

Sorry for the delayed response. Can you try to launch nvcc in a screen?

Hi,

 What is the solution here? I also encounter the same error.

 Thanks!

Hi Raymond,

Did you try running the GPU Test?

Hello!

I have the same error. Here is the info on my server:

 nvcc --version

nvcc: NVIDIA (R) Cuda compiler driver

Built on Tue_Jan_10_13:22:03_CST_2017

Cuda compilation tools, release 8.0, V8.0.61

and the GPU test:

./detect_gpu

Thanks a lot in advance!

Hey Roberto,

Something seems wrong with the GPU setup:

  Device name: ??D

  Memory Bus Width (bits): 0

  Peak Memory Bandwidth (GB/s): 0.000000

Is this on a personal server or is there an IT contact for the cluster you are running on?

There may be an additional module/path required to properly set up the GPU.

Hello Muhammad,

It's on AWS. I installed the CUDA libraries myself so maybe something went wrong during the process. Is there a special way to install the CUDA libraries?

Thanks!

[Muhammad Saad Shamim]

What type of instance?

And is this using the juicer AMI? (ami-458fc22f)

Just rebooted my AWS and it seems to have solved the problem:

Number of devices found: 1

Device Number: 0

  Device name: GRID K520

  Memory Clock Rate (KHz): 2500000

  Memory Bus Width (bits): 256

  Peak Memory Bandwidth (GB/s): 160.000000

However, it seems that my CUDA version is 7.5 now. 

nvcc: NVIDIA (R) Cuda compiler driver

Cuda compilation tools, release 7.5, V7.5.17

I am using the juicetools.jar release that is supposed to run on CUDA 8, but seems to be fine or should I kill the job and download the version that uses CUDA 7.5

java -jar juicer_tools.1.7.6_jcuda.0.8.jar hiccups untreated.hic unt

Reading file: untreated.hic

No valid configurations specified, using default settings

Default settings for 5kb and 10kb being used

Running HiCCUPS for resolution 5000

[Neva Durand]

It should be fine

Thanks a lot for the reply!

Yes, the JCUDA 8 jar bundled in Juicer Tools is backwards compatible with CUDA 6.5/7/7.5.
