A Cache-Conscious Profitability Model for Empirical Tuning of Loop Fusion,s analytical model for profitable loop fusion to be used with a constrained weighted fusion algorithm. We then extend the model to show its effectiveness in the context of an empirical tuning framework. A preliminary evaluation of the model is presented using hand experiments on four applications.

Titanium Performance and Potential: An NPB Experimental Study, to solution. Moreover, we have found that the Titanium implementations of three of the NAS Parallel Benchmarks can match or even exceed the performance of the standard Fortran/MPI implementations at realistic problem sizes and processor scales, while still using far cleaner, shorter and more maintainable code.

Testing Speculative Work in a Lazy/Eager Parallel Functional Language,ions of an Eden program with the computations it actually requires. Thus, the programmer is provided with a profiling tool allowing him to produce better programs where speculative work fits better the actual necessities.

Revisiting Graph Coloring Register Allocation: A Study of the Chaitin-Briggs and Callahan-Koblenz Axamines a particular variant – the Callahan Koblenz allocator – and compares it to the Chaitin-Briggs graph coloring register allocator. Both algorithms were published in the 1990’s, yet the academic literature does not contain an assessment of the Callahan-Koblenz allocator. This paper evaluates an

Register Pressure in Software-Pipelined Loop Nests: Fast Computation and Impact on Architecture DesHowever, SSP schedules require a high number of rotating registers, and may become infeasible if register needs exceed the number of available registers. It is therefore desirable to design a method to compute the register pressure quickly (without actually performing the register allocation) as an
