MONTE CARLO AND GRID SEARCH
ON THE GPUS
Dr.V.Steinhauer
Parallelization for
GPUS with OpenCl and Java
Monte Carlo with 1 000 000
tests per second, triclinic modus
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 :).
