BLAS (Basic Linear Algebra Subprograms) in the C# Language

Abstract

Document the proof of principle study undertaken to rewrite BLAS in the C# language. Comparison of machine floating point precision, error-exit tests, and computational tests between the FORTRAN 90 and C# implementations for Level 1, 2, and 3 BLAS subroutines were completed successfully. Additional comparison tests included DDOT (Level 1), DGER (Level 2), and DSYMM (Level 3) that matched the output from the Intel Math Kernel Library BLAS Code. No optimization was attempted. This working C# language implementation of BLAS defines a starting point to further optimize BLAS in an object-oriented class based .NET language and explore further expansion into the areas of other operating systems (.NET Core is designed to work on Windows, Linux, and macOS operating systems) and cloud computing environments.
