Running sample code: offload error: cannot start process on the device 0 (error code 6)

[Simon_B_7]

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

Number of Target devices installed: 2

Offload sections will execute on: Target CPU (offload mode)

offload error: cannot start process on the device 0 (error code 6)

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.

[Simon_B_7]

Great, that works - thanks for the quick answer!

[Kevin_D_Intel]

Glad that resolved it. Just curious, had you not source'd the compilervars.sh/csh script?  I just wanted to make sure there wasn't a malfunction with that.

[Simon_B_7]

Yes, sourcing the compilervars.sh works. I was using a "module load"  and didn't realise that the compilervars was not getting sourced by default.

[Kevin_D_Intel]

Ah, ok understood. Wish you well going forward!
