I can see good reasons for both options. TBB will make it easier to  
implement task-oriented parallel algorithms, but it brings with it a  
dependency on a non-Boost library. OpenMP is reasonably good at data  
parallelism (and can require fewer changes to algorithms where it  
applies), and depends on features available in many compilers, but it  
isn't as widely applicable as TBB. I think you choice will be dictated  
mainly by the library you choose, and how you think you will need to  
parallelize that library.
