Crate dvcompute_gpss_dist

This crate is a part of discrete event simulation framework DVCompute Simulator (registration number 2021660590 of Rospatent). The dvcompute_gpss_dist crate defines a GPSS-like DSL for optimistic distributed simulation, but the same code base is shared by the dvcompute_gpss_branch crate destined for nested simulation.

The DSL language implements analogs of the following blocks: PREEMPT, RETURN, ASSEMBLE, GATHER, SPLIT, TRANSFER and others. The SELECT block is naturally expressed as a composition of computations. There are analogs of the facility and storage entities.

In general, there are the following main crates: dvcompute (for sequential simulation), dvcompute_dist (for optimistic distributed simulation - from multicore computers till supercomputers), dvcompute_cons (for conservative distributed simulation - from multicore computers till supercomputers) and dvcompute_branch (for nested simulation - theory of games, estimation of the optimal strategy). All four crates are very close. They are based on the same method.

In the case of optimistic distributed simulation, you must satisfy the requirements that the dvcompute_dist crate imposes regarding the dynamic (shared) libraries.

You can find examples in the author’s repository: https://github.com/dsorokin/dvcompute.

The simulation method is described in the author’s article: Sorokin David. DVCompute Simulator for discrete event simulation. Prikladnaya informatika=Journal of Applied Informatics, 2021, vol.16, no.3, pp.93-108 (in Russian). DOI: 10.37791/2687-0649-2021-16-3-93-108
