Abstract:
One of the methods used to evaluate and understand the I/O performance behavior of such applications in new I/O system or different configurations is using modeling and simulation techniques. In this paper, we present a simulation model of the HPC I/O system by using Agent-Based Modelling and Simulation (ABMS) based on the functionality of the I/O Software Stack. Our proposal is modeled using the concept of white box so that the specific behavior of each of the modules or layers in the system can be observed. The I/O software stack layers are analyzed using code instrumentation for the features corresponding to I/O operations and calibration of the initial model. The verification and validation of an initial implementation has shown a similar behavior between the measured and simulated values for the Interleaved or Random (IOR) benchmark by using different file sizes.
