Hi,

I compiled the Sample00c example present in the composer_xe_2013.5.192 directory and I ran it.
This is the output :

Checking for Intel(R) Xeon Phi(TM) (Target CPU) devices...

Number of Target devices installed: 0

Offload sections will execute on: Host CPU (fallback mode)

However, if I do a "lspci | grep o-pro" I get :

29:04:00.0 Co-processor: Intel Corporation Device 225d (rev 11)
94:83:00.0 Co-processor: Intel Corporation Device 225d (rev 11)

And if I run /opt/intel/mic/bin/micinfo :

I also tried many other simple offload codes.
But nothing runs on the xeon phi.

Could you please point me out what is the problem ?

Thank you !

In past instances of similar reports I found the user's environment was not initialized correctly as per compilervars.sh/csh setup scripts.

You can refer to additional details in the earlier post here and then double check that you source'd the compilervars.sh/csh script and that the LD_LIBRARY_PATH variable is setup correctly as discussed in the earlier cited post.

Thanks Kevin,

That worked!
I was using modules to load environment but it appeared that not all variables were loaded by the module...

Best regards!

Excellent! Glad to hear that helped.

Intel Xeon Phi not found using examples but micinfo works
