'No binary for GPU' error uccured from CUDACAST#3 sample

Hello

I’m trying to using OpenACC offloading to NVIDIA(with CUDA).
I downloaded sample code from CUDACast#3 in Youtube.
(cudacasts/ep3-first-openacc-program at master · NVIDIA-developer-blog/cudacasts · GitHub)

I compiled the code with pgcc compiler.
: $ pgcc -acc -Minfo=accel -ta=nvidia,cuda7.0 -o laplace2d_acc laplace2d.c

But after run, I faced error message below
: call to cuModuleLoadData returned error 209: No binary for GPU

I found someone who faced similar error, so I changed ‘double’ to ‘float’.
But error uccur still…
(and I HAVE TO WORK IN UBUNTU)
(cuModuleLoadData error 209)


I installed cuda7.0. And I checked it works through example (deviceQuery).


What do I have to now?? I need your help.


This is my desktop spec.

  • Intel x86_64
  • Ubuntu 14.04.2 LTS
  • NVIDIA GeForce GTX 960 (CUDA Capability number : 5.2)
  • installed CUDA : CUDA 7.0
  • compiler : /opt/pgi/linux86-64/15.4 (TRIAL LICENSE)

This is compile and run log.

Hi soongk.lee,

The problem here is that you’re using a GTX 960. This card uses the Maxwell architecture (compute capability 5.2). Since we officially only support the NVIDIA Tesla product line and Tesla doesn’t have a Maxwell based product, we didn’t produce device code capable of running on a Maxwell.

However, we had enough folks using Maxwell so we went ahead and started adding support in our recent 15.7 release.

Which version of the compiler are you using? Can you try using 15.7?

Thank you mkclog.

I compiled the code with 15.7 version, and It works!
(I used 15.4 version when I had trouble.)

Thank you very much :)
