# Extending Message Passing Interface Windows to Storage

## TL;DR

This paper introduces an extension to the Message Passing Interface (MPI) that allows applications to use storage as a target for one-sided communication, integrating seamlessly with existing MPI implementations.

## Contribution

It presents a novel MPI extension supporting storage-based windows, enabling transparent, low-overhead access to storage for MPI applications.

## Key findings

- Potentially useful for diverse use-cases
- Demonstrates low-overhead performance
- Supports simultaneous storage and memory windows

## Abstract

This work presents an extension to MPI supporting the one-sided communication model and window allocations in storage. Our design transparently integrates with the current MPI implementations, enabling applications to target MPI windows in storage, memory or both simultaneously, without major modifications. Initial performance results demonstrate that the presented MPI window extension could potentially be helpful for a wide-range of use-cases and with low-overhead.
