Using PASSION System on LU Factorization
Haluk Rahmi Topcuoglu, Alok Choudhary · Syracuse University Libraries (Syracuse University) · 1995
Parallel I/0 subsystems are added to massively parallel computers in order to lessen I/0 bottleneck to some extent. Up to now, a few number of parallel software systems have been designed and implemented to assist programmers in I/0 intensive applications; PASSION is one of them. By providing parallel I/0 support at the language, compiler and run-time level, PASSION system explores the large design space of parallel systems. The target of this paper is to show the performance benefits of using PASSION I/0 libraries at runtime in comparison with using conventional parallel I/0 primitives for high performance parallel I/0 in LU factorization kernel, a very widely used scientific kernel.
