Abstract

We use Lomonosov-2 supercomputing facility for the generation of extensive air shower events with Cherenkov light which is a rather time consuming procedure. At primary energies slightly below 100 PeV a substantial part of events are killed before reaching their end while exceeding the queue time limit. The fact compelled us to develop a multithread version of the code. We report here the main features of our development as well as some evidence of its efficiency.
