Performance of Software for the Full Symmetric Eigenproblem on CRAY T3E and T90 Systems

摘要

MPP systems with a message-passing programming paradigm such as CRAY T3E still play an important role in high performance scientific computing and so there is need for basic numerical software for those systems. There are several libraries for numerical linear algebra computations with message-passing available most of which are public domain libraries. The eigensystem solvers of some of these libraries are compared taking into account not only performance but also user-friendliness. Furthermore, the results attained on a PVP CRAY T90 vector supercomputer with shared-memory parallelism are discussed.
