==Difficulties==

Automatic parallelization by compilers or tools is very difficult due to the following reasons:

* dependence analysis is hard for code using indirect addressing, pointers, recursion, and indirect function calls.;

* loops have an unknown number of iterations;

* and accesses to global resources isare difficult to coordinate: in terms of memory allocation, I/O, and shared variables.
