Why CMAQ has no problems I have no idea (are you running pre-compiled executables?).
You probably found libiomp.so* in some directory like (in my case) /opt/intel/composer_xe_2013_sp1.0.080/compiler/lib/intel64/ This library is needed for your compile of the I/O API, and comes from Intel.
The usual way to install these compilers (when done correctly) has your login procedure source the relevant resource-file in order to set up the environment for the compiler. In my case, I have
/etc/profile.d/local.csh do the command:
source /opt/intel/composer_xe_2013_sp1.0.080/bin/compilervars.csh intel64
in order to set up the compiler’s environment.
In a module environment, make sure you do the correct module load command before running SMOKE.
