Ultrasonic (US) simulation has become a widely adopted method to design and evaluate imaging sequences and image analysis algorithms. Among US simulators, FIELD-II is an acknowledged reference but simulating the acquisition of 3D+t processes like the beating heart requires days of CPU time. A deployment of FIELD-II on EGEE is presented, based on a setup made of VBrowser (GUI), DIANE (pilot jobs) and MOTEUR (workflow management). Since FIELD-II is developed in Matlab, it is compiled and the resulting binary is run on sites of the biomed VO using the Matlab Compiler Runtime. Data parallelism on lines of the image as well as on the simulated mediums can thus be exploited. Based on an extensive set of experiments, performance and reliability are then discussed. Error causes are identified and solutions to overcome them are proposed. Overall, this first implementation brings the simulation time of a 2D+t cardiac cycle from 16h to 3h and the global error ratio has been reduced from 16% to 2%
