MONTE CARLO AND GRID SEARCH ON THE GPUS

Dr.V.Steinhauer
  1. Parallelization for GPUS with OpenCl and Java

  2. Monte Carlo with 1 000 000 tests per second, triclinic modus

  3. Grid search with 1 000 000 tests per second, triclinic modus

 

  • The goal of this topic is a control of software/hardware state to find the unit cell parameters in the powder diffraction analyse direct. It means, searching in big branch for the real time, for example, 1 hour. As a hardware is used the graphic not expansive cards ( in this case from NVIDIA GeForce GT 320 ~ 72 cores and ~ 25 price). For example with NVIDIA GeForce GTX 690 the 40 000 000 tests per second is possible. It means 144 000 000 000 tests per hour. If we have 10 values for each D,E,F coeffizients, then we will get 144 000 000 variation for ABC, or about 1000 values for each parameters ( the restrictions included) or in the branch 5-25 A the prezision 0.02 A. And it is no the limit :).
