We developed an OpenMP compiler, called Omni. This paper describes a performance evaluation of the Omni OpenMP compiler. We take two commercial OpenMP C compilers, the KAI GuideC and the PGI C compiler, for comparison. Microbenchmarks and a program in Parkbench are used for the evaluation. The results using a SUN Enterprise 450 with four processors show the(More)
This paper presents methods for generating communication on compiling HPF programs for distributed-memory machines. We introduce the concept of an iteration template corresponding to an iteration space. Our HPF compiler performs the loop iteration mapping through the two-level mapping of the iteration template in the same way as the data mapping is(More)
In this paper, we present parallel implementations of the sparse Cholesky factorization kernel in the SPLASH-2 programs to evaluate performance of a Pentium Pro based SMP cluster. Solaris threads and remote memory operations are utilized for intranode parallelism and internode communications, respectively. Sparse Cholesky factorization is a typical(More)
