Unifying Unitary and Hyperbolic Transformations
In this paper we describe uniied formulas for unitary and hyperbolic reeections and rotations, and show how these uniied transformations can be used to compute a Hermitian triangular decomposition ^ R H D ^ R of a strongly nonsingular indeenite matrix ^ A given in the form ^ The uniication is achieved by the introduction of signature matrices which determine whether the applicable transformatio...
متن کاملParallelizing / Optimizing Frontend Machine - Independent Backend
PROMIS is a multilingual, parallelizing, and retargetable compiler with an integrated frontend and backend operating on a single uniied/universal intermediate representation. This paper describes the organization and the major features of the PROMIS compiler. PROMIS exploits multiple levels of static and dynamic parallelism, ranging from task-and loop-level parallelism to instruction-level para...

متن کاملA Uniied Approach to Strictness Analysis and Optimising Transformations
We present an inference system for translating programs in a PCF-like source language into a variant of Moggi's computational lambda calculus. This translation combines a simple strictness analysis with its associated optimising transformations into a single system. The correctness of the translation is established using a logical relation between the denotational semantics of the source and ta...
متن کاملComputational Alignment: a New, Uniied Program Transformation for Local and Global Optimization Computational Alignment: a New, Uniied Program Transformation for Local and Global Optimization
Computational Alignment is a new class of program transformations suitable for both local and global optimization. Computational Alignment transforms all of the computations of a portion of the loop body in order to align them to other computations either in the same loop or in another loop. It extends along a new dimension and is signiicantly more powerful than linear transformations because i...
