User Guide to PIC
A portable Fortran utility library for scientific computing
PIC (a Huastec word meaning “otter”) is a portable Fortran utility library providing commonly needed features with first-class support across multiple compilers.
Why PIC?
The Fortran ecosystem lacks a standard library that compiles reliably across all compilers. While the Fortran stdlib project aims to fill this gap, it doesn’t build on compilers like nvfortran. PIC exists to provide portable utilities that work everywhere.
Key Features:
Strings, logging, timers, arrays, sorting, hashing
Tested on GNU, Intel, NVIDIA HPC, LFortran, Cray, and Flang
Two build systems: CMake and FPM
MIT licensed and open source
Quick Start:
program main
use pic, only: pic_print_banner
implicit none
call pic_print_banner()
end program main
