Chapter 1: Introduction

Platform Computing’s LSF software is a distributed computing resource management tool that you can use with either the serial or the parallel version of Ansys Fluent. This document provides general information about running Fluent under LSF, and is made available via the Ansys, Inc. website for your convenience. Contact Platform directly for support of their product.

Using LSF, Fluent simulations can take full advantage of LSF checkpointing (saving Fluent .cas and .dat files) and migration features. LSF is also integrated with various MPI communication libraries for distributed MPI processing, increasing the efficiency of the software and data processing.


Important:  Running Fluent under LSF is not supported on Windows.


Platform’s Standard Edition is the foundation for all LSF products, it offers users load sharing and batch scheduling across distributed Linux and Windows computing environments. Platform’s LSF Standard Edition provides the following functionality:

  • comprehensive distributed resource management

    • provides dynamic load sharing services

    • allows for batch scheduling and resource management policies

  • flexible queues and sharing control

    • prioritizes jobs

    • schedules jobs with load conditions

    • processes jobs with time windows

    • provides limits on the number of running jobs and job resource consumption

  • fair-share scheduling of limited resources

    • manages shares for users and user groups

    • ensures fair sharing of limited computing resources

  • maximum fault tolerance

    • provides batch service as long as one computer is active

    • ensures that no job is lost when the entire network goes down

    • restarts jobs on other compute nodes when a computer goes down
