SimGrid is a framework for simulating applications on distributed computing systems. [3] It provides high-level programming language tools for comparing, evaluating, analyzing, and prototyping algorithms across different platforms. SimGrid has been used to conduct experimental simulations in multiple domains, including cluster computing, grid computing, heuristics and peer-to-peer (P2P) computing. [1]
SimGrid is distributed as freeware under the GNU Lesser General Public License version 2.1 (LGPL-2.1-only). [4] [2]
SimGrid started in 1999 as a joint research project between Henry Casanova and Arnaud Legrand from the University of California, San Diego and École Normale Supérieure de Lyon, respectively. [5] The original design was only used for simulating the scheduling of heuristics for heterogeneous platforms. [5]
SimGrid has received funding from national and international research agencies and has evolved through various projects, including SONGS, USS-SimGrid, and ASTR. [6]

SimGrid supports multiple programming languages, including C++ and Python, through models and APIs.
SimGrid provides tools for analyzing scheduling, resource allocation, fault tolerance, and other aspects of distributed computing through four distinct interfaces:

This paper focuses on SimGrid v2, which greatly improves on the first version of the software with more realistic network models and topologies. SimGrid v2 also enables the simulation of distributed scheduling agents, which has become critical for current scheduling research in large-scale platforms.
