Execution time of high-precision BLAS Level 1 operations on Intel Core i5-4590 and NVIDIA Turing RTX 2060

This dataset contains the execution time of four BLAS Level 1 operations - ASUM, DOT, SCAL and AXPY - implemented using extended- and multiple-precision software for central processing units (CPUs) and CUDA compatible graphics processing units (GPUs). The experiments were conducted on an Intel Core i5-4590 processor and an NVIDIA Turing RTX 2060 graphics card. Each raw file provided contains the results of three test runs and details about the experimental setup. For each test run, the BLAS function was repeated ten times, and the total execution time of ten iterations (in milliseconds) was measured. For comparison purposes, the execution time of double precision routines from the OpenBLAS and cuBLAS packages is also presented. The complete source code for the tests can be found at https://github.com/kisupov/mpres-blas. The following software are considered that provide computations with extended or multiple precision: For CPU: • MPFR (https://www.mpfr.org), • ARPREC (https://www.davidhbailey.com/dhbsoftware), • MPDECIMAL (https://www.bytereef.org/mpdecimal), • MPACK (http://mplapack.sourceforge.net), • XBLAS (https://www.netlib.org/xblas).
