-----------------------------------

Hi Andrew,

Can you suggest where to get the correct iccvars.sh script or how to change it? 
I only have one iccvars.sh in /opt/intel/cce/10.0.025/bin and I don't see any 
options that control which type of code the compiler generates. Is it possible 
that the compiler doesn't support 32-bit code on x86_64 and that I need to 
install another one?

Thanks!
