All benchmarks are platform-independent (run on any computing device with appropriate hardware). CuPy tests require an NVIDIA GPU with CUDA toolkit installed.
This command prepares Python prereqs:
pip install -e .
Using the C and/or Fortran tests requires compilation using CMake.
cmake -B build cmake --build build --target test # non-Visual Studio cmake --build build --target RUN_TESTS # Visual Studio
Iterative benchmarks, here using the pisum algorithm:
Matrix Multiplication benchmarks:
hypot() is faster from 1 to a few hundred elements, then
sqrt(x^2+y^2) becomes slightly faster. However,
hypot() does not
overflow for arguments near REALMAX. For example, in Python:
from math import sqrt, hypot a=1e154; hypot(a,a); sqrt(a**2+a**2); 1.414213562373095e+154 inf

Julia binaries are often downloaded to a particular directory.
Python doesn't pickup
.bash_aliases, which is commonly used to point to Julia.

GNU Fortran (gfortran ≥ 6 required):

We give a hint to CMake where your MKL libraries on. For example:
MKLROOT=/opt/intel/mkl cmake ..
Of course this option can be combined with
You can set this environment variable permanently for your convenience
(normally you always want to use MKL) by adding to your
