The ROme OpTimistic Simulator

Welcome to the ROOT-Sim website! ROOT-Sim is a HPC library targeting optimistic simulation. This runtime environment is able to deliver very fast simulation runs on massively parallel multicore machines and or distributed compute clusters/supercomputers.

If you want to have more information on how ROOT-Sim can fit your purposes, or if you want to contribute to the project, the wiki is a good place to start. The about page shows few steps to get ROOT-Sim running, using some of the example models provided in the distribution.

If you have found a bug, or if you want to request a new feature, feel free to open a new issue on Github.
