Abstract

The mainstream architecture of a parallel machine with more than tens of processors is a distributed-memory machine. The bulk synchronous task scheduling problem (BSSP, for short) is an task scheduling problem for distributed-memory machines. This paper shows that there does not exist a 驴-approximation algorithm to solve the optimization counterpart of BSSP for any 驴 P = NP.
