Hello,

I have compiled the sample code using Intel(R) C Intel(R) 64 Compiler XE for applications running on Intel(R) 64, Version 13.1.3.192 Build 20130607 on a newly installed server with 2 phi cards

The code compiles OK, but gives an error upon running, see below

./intro_sampleC.out
offload error: cannot find MIC executable offload_main

Number of Target devices installed: 2

Try setting the following env-variable and re-running:

MIC_LD_LIBRARY_PATH=/opt/intel/composer_xe_2013.5.192/compiler/lib/mic:/opt/intel/mic/coi/device-linux-release/lib:/opt/intel/mic/myo/lib

This one should have been set by sourcing the compilervars.sh/csh script.

Great, that works - thanks

Ah, ok understood. Wish you
