Query: Simulation-Based Performance Prediction of HPC Applications: A Case
  Study of HPL   We propose a simulation-based approach for performance modeling of parallel
applications on high-performance computing platforms. Our approach enables
full-system performance modeling: (1) the hardware platform is represented by
an abstract yet high-fidelity model; (2) the computation and communication
components are simulated at a functional level, where the simulator allows the
use of the components native interface; this results in a (3) fast and accurate
simulation of full HPC applications with minimal modifications to the
application source code. This hardware/software hybrid modeling methodology
allows for low overhead, fast, and accurate exascale simulation and can be
easily carried out on a standard client platform (desktop or laptop). We
demonstrate the capability and scalability of our approach with High
Performance LINPACK (HPL), the benchmark used to rank supercomputers in the
TOP500 list. Our results show that our modeling approach can accurately and
efficiently predict the performance of HPL at the scale of the TOP500 list
supercomputers. For instance, the simulation of HPL on Frontera takes less than
five hours with an error rate of four percent.
