Summer Report: Tool Integration for Variable-Precision Computing

Technical Report Lam, Michael

This summer I worked in the tools group of the variable-precision computing effort at Lawrence Livermore National Laboratory (LLNL). I coordinated an integration project that combined three existing tools into a single pipeline for automated mixed-precision tuning at the source code level. This involved coordinating efforts between several different project groups and making improvements to all three tools. Two of the tools are already available publicly as open-source projects, and the third has been submitted for release. This document serves as an overview of the summer's efforts, focusing on our contributions as well as ideas for future work.

Dynamic variable precision computation

Patent Sadowski, Greg; Burleson, Wayne

A conversion unit converts operands from a conventional number system that represents each binary number in the operands as one bit to redundant number system (RNS) operands that represent each binary number as a plurality of bits. An arithmetic logic unit performs an arithmetic operation on the RNS operands in a direction from a most significant bit (MSB) to a least significant bit (LSB). The arithmetic logic unit stops performing the arithmetic operation prior to performing the arithmetic operation on a target binary number indicated by a dynamic precision associated with the RNS operands. In some cases, a power supplymore »« less

Replicated Computational Results (RCR) Report for "Adaptive Precision Block-Jacobi for High Performance Preconditioning in the Ginkgo Linear Algebra Software''

Technical Report Osborn, S.

In, a practical implementation of a novel adaptive precision block-Jacobi preconditioner is introduced. In particular, the authors present a heavily-tuned GPU implementation of the adaptive precision block-Jacobi preconditioner within the Ginkgo numerical linear algebra library. The performance of the methodology and implementation is demonstrated using the proposed preconditioning scheme within Ginkgo’s high-performance Conjugate Gradient (CG) implementation on an NVIDIA Volta GPU. In this report, we replicate a subset of the computational results presented in. The focus is generating results from Fig. 9 to evaluate the performance of using Ginkgo’s CG solver integrated with either the full or the adaptive precisionmore »« less

On computing ``accurate'' derivatives of Equation-of-State variables

Technical Report Shestakov, A.

We analyze a log-log interpolant for 2D EOS lookups, where the EOS independent variables are, say, T and ρ. If the data f (Ti, ρj) are in the form of a power law, even locally, the interpolant is exact.
