running offload code on node without a mic

Hi again, i'd like to run my #pragma offload code on a node that does not have a mic present. When I try I get the following error:

"offload error: cannot offload to MIC - device is not available"

Is there a flag to tell the software to run the CPU only based version? I thought the binary had both code paths, so it should just choose a sensible one for what is available?

Thanks for your help.

Regards,

Josh
