Experiences on Parallelizing Compilation for Development and Porting of Large Scale Applications on Distributed Memory Parallel Systems∗
High level environment, such as High Performance Fortran (HPF), supporting the development of parallel applications and porting of legacy codes to parallel architectures have not yet gained a broad acceptance and diffusion. Common objections claim difficulty of performance tuning, limitation of its application to regular, data parallel computations, and lack of robustness of parallelizing HPF c...
متن کاملNAS Experiences of Porting CM Fortran Codes to HPF on IBM SP2 and SGI Power Challenge
Current Connection Machine (CM) Fortran codes developed for the CM-2 and the CM-5 represent an important class of parallel applications. Several users have employed CM Fortran codes in production mode on the CM-2 and the CM-5 for the last five to six years, constituting a heavy investment in terms of cost and time. With Thinking Machines Corporation’s decision to withdraw from the hardware busi...

متن کاملHPFStab: An HPF Conjugate Gradient Library
In this paper we present a case study of porting of a Conjugate Gradient library from CM Fortran on a Connection Machine 5 to High Performance Fortran (HPF) on a Silicon Graphics Power Challenge, addressing the issues of portability and performance. Conjugate Gradient Methods (CGM) are a broad category of linear algebra methods for solving the generalized equation A x= b. Through the process of...
