An optical laboratory matrix–vector processor is used to solve parabolic differential equations (the transient diffusion equation with two space variables and time) by an explicit algorithm. This includes optical matrix–vector nonbase-2 encoded laboratory data, the combination of nonbase-2 and frequency-multiplexed data on such processors, a high-accuracy optical laboratory solution of a partial differential equation, new data partitioning techniques, and a discussion of a multiprocessor optical matrix–vector architecture.

Mutation analysis is a software testing methodology designed to substantiate the correctness of a program Phi . The mutation approach is to induce syntactically correct changes in Phi , thereby creating a set of mutant programs. The goal of a tester is to construct a set of test data T that distinguishes the output of Phi (T) from that of all mutant programs. Test data sensitive enough to distinguish all mutant programs is deemed adequate to infer the probable correctness of Phi . An algorithm is proposed which was designed to exploit the architecture of a vector processor like the Cyber 205 or Cray X/MP. The algorithm manages the simultaneous execution of multiple mutant Fortran 77 programs. This is accomplished by viewing the execution of these mutants as a sequence of vector instructions. The algorithm promises potential to greatly increase the performance of a mutation-based testing system, as well as points towards a general method of simultaneous program execution against multiple data sets.< >
