I am using pgi version 12.8
Enable for cuda and pgaccelerators.

But I am facing problems about the LD_LIBRARY_PATH.


Quote:
#pgaccelinfo -v
libcuda.so not found
libamdcalcl.so not found
No accelerators found.
Check that you have installed the CUDA or CAL libraries properly
Check that your LD_LIBRARY_PATH environment variable points to the CUDA or CAL runtime installation directory


I could build the matrix multiplication example with accelator and build with the following options
Quote:
pgfortran -fast -acc - Minf -g -pg matrx-acc.f90


Then after qsub to my cluster i got the gmoun.out

Then I tried to use the pgcollect and pgprof

Quote:
pgcollect a.out
libcuda.so not found, exiting
Please check that the CUDA driver is installed and the shared object is in the install directory or on your LD_LIBRARY_PATH.
target process abnormal termination: Error: process received signal: Exception
no profile generated


The visual pgprof also failed.

Cuda is installed in my /usr/local but the cudalib.so does not exist there.
Quote:
ls /usr/local/cuda/lib64/
libcublas.so libcufft.so libcurand.so libnpp.so
libcublas.so.4 libcufft.so.4 libcurand.so.4 libnpp.so.4
libcublas.so.4.2.9 libcufft.so.4.2.9 libcurand.so.4.2.9 libnpp.so.4.2.9
libcudart.so libcuinj.so libcusparse.so
libcudart.so.4 libcuinj.so.4 libcusparse.so.4
libcudart.so.4.2.9 libcuinj.so.4.2.9 libcusparse.so.4.2.9


Could you give any advice because this is critical issue for me to start parallelizing my project.

Thank you.
Koffi

Hi Koffi,

It appears that you don't have a CUDA driver or NVIDIA GPU installed on this system.

You can find information on the CUDA driver at: http://www.nvidia.com/Download/index.aspx?lang=en-us or the full CUDA SDK (which includes an option to install the driver) at https://developer.nvidia.com/cuda-downloads.

Hope this helps,
Mat

Thank very much mkcolg.

I think you are right when looking to the follwing
Code:
$ lspci | grep nvidia
response: (no reply)
$ nvidia-smi
-bash: nvidia-smi: command not found



I will ask the system adminstrator to install because i do not have the root permission
