ForDot: A Fortran library that overloads the dot_product function to enable efficient dot product with/without coarray.

Usage

use fordot

a = dot_product(u,v,coarray,option,nblock)

• coarray is an optional logical variable. Set it to .true. and use the -DUSE_COARRAY flag to enable coarray.

• nblock is an optional integer variable.

• options is an optional character variable. Available options are 'm1' to 'm4', and the default option is 'm2'.

• Note: Use the flag -DUSE_DO_CONCURRENT to enable do concurrent. This implementation of do concurrent is currently only supported by the Intel Compiler (ifx).

Requirements

• A Fortran Compiler
• BLAS Library
• Fortran Package Manager (fpm)

fpm Dependency

If you want to use ForDot as a dependency in your own fpm project, you can easily include it by adding the following line to your fpm.toml file:

[dependencies]
fordot = {git="https://github.com/gha3mi/fordot.git"}

Runing Tests

Execute the following commands to run tests with specific compilers:

fpm @<compiler>-test

compiler: ifx, ifort, gfortran, nvfortran

For coarray testing use:

fpm @<compiler>-test-coarray

compiler: ifx, ifort

All compiler options are accessible in the fpm response file fpm.rsp.

Benchmarks

You can find benchmark results on ForBenchmark.
