Acceleration of linear congruential generators

For implementation of pseudo-random number generators (PRNG), a linear congruential generator (LCG) is the most frequently used algorithm. The techniques to increase the efficiency of the LCG based on 64-bit integers and bit-wise operations are studied. The efficiency of the LCG implementation with the techniques proposed is experimentally tested.

Parallel simulation of asynchronous Cellular Automata evolution

For simulating physical and chemical processes on molecular level, asynchronous cellular automata with probabilistic transition rules are widely used being sometimes referred to as Monte-Carlo methods. The simulation requires a huge cellular space and millions of iterative steps for obtaining the CA evolution representing a real scene of the process....

A version of the particle-in-cell method with adaptive mass alteration for the silane plasma simulation

A new method is proposed to reduce non-physical effects in the PIC method. The method is demonstrated on an example of simulation of recombination of positive and negative ions in the radio frequency (RF) discharge.

In discharges in electro-negative gases, the negative ions are generated by dissociative attachment and lost...
