Programlibraries are one tool to make the cooperation between specialists from various elds successful: the separation of application-speci c knowledge from applicationindependent tasks ensures portability, maintenance, extensibility, and exibility. The current paper demonstrates the success in combining problem-speci c knowledge for the quadratic assignment problem QAP with the rawcomputing power o ered by contemporary parallel hardware by using the library of parallel search algorithms ZRAM. Solutions of previously unsolved large standardtest-instances of the QAP arepresented.
