With multi-core processors becoming mainstream, programmers are trying to take full advantage of their parallel possibilities. One of the relatively new and powerful multi-core CPUs is the Cell Broadband Engine Architecture, which excels at floating point calculations. To ease development on this platform suitable for supercomputing, frameworks have been created offering a range of programming models. One of these frameworks is CellFS. There has been progress on making CellFS available for the x86 architecture, providing a way to test and run code without the need for actual Cell hardware. CellFS on x86 supports coroutines using a straightforward implementation based on setcontext/getcontext. A different and perhaps more promising way to realize coroutines is using pthreads; the possibility and feasibility of such a solution is investigated.
