The OpenSim Project and the National Center for Simulation in Rehabilitation Research (NCSRR) at Stanford invite you to join our next webinar, featuring Colin Smith and Darryl Thelen, University of Wisconsin-Madison.
DETAILS
Title: Enabling Stochastic Simulations of Movement with High Throughput Computing
Speakers: Colin Smith and Darryl Thelen, University of Wisconsin-Madison
Time: Thursday, November 17, 2016 at 10:00 a.m. Pacific Standard Time
Registration: https://simtk.webex.com/simtk/onstag...9d0f9bafc73c41
DESCRIPTION
Musculoskeletal simulations of movement are traditionally performed using generic models with assumed parameters and geometries. Thus, population variability and parametric uncertainty become critically important to consider when interpreting model predictions. High Throughput Computing (HTC) systems allow thousands of independent simulations to be performed in parallel, enabling probabilistic analyses to assess the sensitivities inherent in your results. We will present an overview of HTC and an HTC enabled stochastic simulation framework developed to investigate cartilage loading in the knee during movement. We will present the results of several HTC enabled studies focusing on validation in the presence of parametric uncertainty, multifactorial sensitivity analysis and structure-function relationships. Finally, we will demonstrate how to perform OpenSim simulations on the Open Science Grid, an HTC resource freely available to US researchers (and their collaborators).
