SUMMARY:Simulation-Based Performance Prediction of HPC Applications: A Cas
 e Study of HPL
DESCRIPTION:Workshop\n\nSimulation-Based Performance Prediction of HPC App
 lications: A Case Study of HPL\n\nXu, Jiang, Ibeid, Svilan, Bian\n\nWe pro
 pose a simulation-based approach for performance modeling of parallel appl
 ications on high-performance computing platforms. Our approach enables ful
 l-system performance modeling: the hardware platform is represented by an 
 abstract yet high-fidelity model and the computation and communication com
 ponents are simulated at a functional level, where the simulator allows th
 e use of the components native interface.  This results in a fast and accu
 rate simulation of full HPC applications with minimal modifications to the
  application source code. This hardware/software hybrid modeling methodolo
 gy allows for low overhead, fast and accurate exascale simulation and can 
 be easily carried out on a standard client platform (desktop or laptop). W
 e demonstrate the capability and scalability of our approach with High Per
 formance LINPACK (HPL), the benchmark used to rank supercomputers in the T
 op500 list. Our results show that our modeling approach can accurately and
  efficiently predict the performance of HPL at the scale of the Top500 lis
 t supercomputers. For instance, the simulation of HPL on Frontera takes le
 ss than five hours with an error rate of four percent.\n\nRegistration Cat
