Parallel Monte-Carlo Tree Search for HPC Systems

Abstract. Monte-Carlo Tree Search (MCTS) is a simulation-based search method that brought about great success to applications such as Computer-Go in the past few years. The power of MCTS strongly depends on the number of simulations computed per time unit and the amount of mem-ory available to store data gathered during simulation. High-performance computing systems such as large compute clusters provide vast compu-tation and memory resources and thus seem to be natural targets for running MCTS. However, so far only few publications deal with par-allelizing MCTS for distributed memory machines. In this paper, we present a novel approach for the parallelization of MCTS which allows for an equally distributed spreading of both the work and memory load among all compute nodes within a distributed memory HPC system. We describe our approach termed UCT-Treesplit and evaluate its per-formance on the example of a state-of-the-art Go engine

Environmental monitoring of plutonium at ultratrace level in natural water (Sea of Galilee - Israel) by ICP-SFMS and MC-ICP-MS

An analytical method for the determination of plutonium concentration and its isotope ratio at ultratrace level in natural water by inductively coupled plasma mass spectrometry (ICP-MS) is proposed. In order to preconcentrate Pu and to avoid matrix effects and clogging effects on the cones during the mass spectrometric measurements, an effective Pu separation procedure (on TEVA resin) from the matrix was applied. Studies of the separation procedure for 2.1 pg of Pu-242 spiked into 100 L of lake water from the Sea of Galilee result in a recovery of 62%. The detection limits of Pu-239 in 100 L lake water were determined as 1x10(-19) g mL(-1) and 3x10(-20) g mL(-1) using ICP-SFMS and MC-ICP-MS, respectively. Pu-239 was detected in the Sea of Galilee at a concentration level of about 3.6x10(-19) g mL(-1) with a Pu-240/Pu-239 isotope ratio of 0.17. This measured plutonium isotope ratio is the most probable evidence of plutonium contamination of the Sea of Galilee as a result of global nuclear fallout after the nuclear weapons tests in the sixties. This paper discusses applications of double-focusing sector field ICP-MS with single and multiple ion collection for the quantitative determination of plutonium and its isotope ratio at the 10(-19) g mL(-1) level in natural water
