Efficient Quantum Monte Carlo Solutions on Supercomputers – How Close are We to the Real Quantum Computer?


n order to determine how close we are to the "real quantum computer" the Wigner Monte Carlo method is considered. A short analysis of the convergence of the Signed Particle Formulation of Quantum Mechanics will be given. Extensive numerical experiments with Monte Carlo, quasi-Monte Carlo (QMC), and scrambled quasi-Monte Carlo algorithms based on Sobol sequences will be presented to support the theoretical studies. Main conclusions will be drawn from numerical tests which were executed on massively parallel supercomputers and some exciting results will be presented.


In addition, recent developments of PetaSC supercomputers will be given with a focus on the Opens external link in new windowDiscoverer supercomputer.

The presentation includes:

System overview:

- Compute node design
- High performance Network
- High-speed Interconnect network topology

Software Environment:

- System Software (Operating system and Compiler Suites)
- Numerical libraries
- Debugging/profiler tools
- Resource and workload manager
