# intel-openmp — Intel OpenMP* Runtime Library

License: unclear · Maintenance: active · Downloads: 983.2K/mo

## What it is and what it does

Intel OpenMP is a runtime library that provides OpenMP API support for Intel's compiler suite (C, C++, and Fortran). It enables developers to write multithreaded code using shared-memory parallelism that runs efficiently on multi-core x86_64 processors. The package distributes precompiled dynamic libraries for Windows systems.

This is a system-level dependency rather than a general-purpose library. It is typically installed as a transitive dependency of packages built with Intel compilers, or directly when using Intel's development tools. The medium install friction reflects its platform-specific nature and compiled runtime dependency, making it suitable only for Windows x86_64 environments where Intel compiler tooling is in use.

Use it for:

- Running Python packages compiled with Intel C/C++ extensions that use OpenMP for parallelism.
- Developing multithreaded Fortran or C/C++ code via Intel compilers that needs to run on Windows.
- Enabling shared-memory parallel execution in scientific computing workflows on Windows x86_64 systems.
- Satisfying runtime dependencies for Intel oneAPI-based tools and libraries on Windows.

## Worth the install?

AI-flagged interpretation of the facts above — verify before relying.

Provides Intel's OpenMP runtime library for x86_64 Windows systems, enabling multithreaded execution support for Intel C, C++, and Fortran compilers.

Yes, if you are using Intel compilers or packages built with them on Windows x86_64. No, if you are not targeting Intel tooling or are on a different platform. The proprietary license and platform specificity mean this is a specialized dependency, not a general utility—install only when required by your compiler or a dependent package.

## Install

pip install intel-openmp
uv add intel-openmp
poetry add intel-openmp

## Installing intel-openmp

Before you install: Active maintenance with a recent release (16 days old). Medium install friction due to platform-specific wheels and a compiled runtime dependency (intel-cmplr-lib-ur), indicating this is a specialized system library rather than a pure Python package.

License in practice: Licensed under Intel End User License Agreement for Developer Tools with unclear treatment classification. This is a proprietary license requiring review of Intel's terms before use in commercial or redistributed projects.

Quickstart:

pip install intel-openmp==2026.1.1

import intel_openmp
# OpenMP runtime is now available to Intel compilers and dependent packages

Windows x86_64 system required; intel-cmplr-lib-ur runtime dependency must be available; intended for use with Intel C/C++/Fortran compilers, not as a standalone library.

Verify before relying:

- Whether this package can be installed and used on non-Intel compiler toolchains or if it is strictly tied to Intel compiler products.
- Exact Python version compatibility, as requires_python is unspecified in the fact sheet.
- Whether the proprietary Intel End User License Agreement permits redistribution in packaged applications.
