7.2.5 Conclusion

Large scale numerical simulations are becoming increasingly important in many areas of science. Lattice QCD calculations have been commonplace in high energy physics for many years. More recently, this technique has been applied to string theories formulated as dynamically triangulated random surfaces. As we have pointed out, such computer simulations of strings are difficult to implement efficiently on all but MIMD computers, due to the inherent irregular nature of random surfaces. Moreover, on most MIMD machines, it is possible to get 100% speedup by doing multiple independent Monte Carlos, since an entire simulation easily fits within each processor.
