Modules

simple interface module that prints banner and other information about the library mostly here to verify installs, etc.

Please do not modify this file to implement new methods, please go look at tools/autogen/pic_array_cpu.fypp and edit the generator.

The stdlib_ascii module provides procedures for handling and manipulating intrinsic character variables and constants.

Two unrelated notions of time, kept apart on purpose.

this will be the physical constants module

Unified error handling with stack traces for PIC. Use error_t as an intent(out) or intent(inout) argument to propagate errors with context through call chains.

pic_flop_rate is a convenient encapsulation of the flop_recorder and pic_timer it is used to measure the flop rate of a given operation, and report it

Deterministic, compiler independent formatting of reals and integers.

Shortest-path and traversal algorithms on a weighted directed graph stored as a csr_t from pic_csr.

An implementation of the FNV hashes 1 and 1a of Glenn Fowler, Landon Curt Noll, and Kiem-Phong-Vo, https://en.wikipedia.org/wiki/Fowler–Noll–Vo_hash_function

A concrete binary heap keyed by integer(int64) and carrying an integer(int32) payload. This is the data structure behind Dijkstra, A*, k-nearest searches and discrete-event simulation loops.

a simple module that collects phrases and prints them out randomly, like fortune

This module provides small, elemental numeric helpers that are commonly needed but missing from the Fortran intrinsics: clamp, is_in_range and is_close. All procedures are elemental, so they apply equally to scalars and to arrays of any rank/shape.

Lightweight profiler for named code regions with optional NVTX support

Distributions whose output is an integer or a logical, and which are therefore bit-identical on every supported compiler.

Portable, reproducible pseudo-random number generators.

Growth, resize, serialization and state-hash primitives shared by every struct-of-arrays container.

This module implements overloaded sorting subroutines named ORD_SORT, SORT_INDEX, and SORT, that each can be used to sort two kinds of INTEGER arrays, two kinds of REAL arrays, character(len=*) arrays

This module provides simple reductions over rank-1 arrays. To avoid precision loss and integer overflow, mean, variance and std_dev always accumulate in and return real(dp), regardless of the input type. min_max preserves the input type and returns the two extremes in a length-2 array.

This module implements basic string handling routines.

contains a simple timer module to measure and record time

main module for defining types for integer and double precision

Growable vectors: push_back, pop_back, at, and amortised O(1) growth over heap storage.
