摘要：
Parallel algorithms are presented for the Fourier pseudospectral method and parts of the Chebyshev pseudospectral method. Performance of these schemes is reported as implemented on the NCUBE hypercube. The problem to which these methods are applied is the time integration of the incompressible Navier-Stokes equations. Despite serious communication requirements, the efficiencies are high; e.g., 92% for a 1283 mesh on 1024 processors. Benchmark timings rival those of optimized codes on supercomputers. © 1990.
