check_cp: Checks for Checkpointed Rdata Files

In statnet/EpiModelHPC: EpiModel Extensions for High-Performance Computing

Checks for Checkpointed Rdata Files

Description

Checks whether there are checkpointed data files in a specific format given a simulation number.

Usage

check_cp(simno)

Arguments

simno

Simulation number for current model simulation, typically stored in control$simno.

Details

This function checks whether checkpointed data files are available for loading. Checkpointed data files are incrementally saved during the simulation and loaded when a simulation job has been cancelled and restarted. This is done automatically within the netsim_hpc function.

Checkpointed data files are searched for in a specific subdirectory relative to the current working directory: data/sim<x>, where <x> is the simno value. Within that directory check_cp looks for files ending .cp.rda, which is the standard checkpoint data file name. Note that these standards for file directory and name are consistent with the save_cpdata module function. If running simulations using the netsim_hpc function, this data saving module will automatically be inserted in the workflow of a simulation.

The files are tested to see that they are of similar size, meaning that no file is less than 50% of the average file size of the others. Smaller size files usually indicates that the interim file saving was interrupted. If the files exist and are of correct size, a full directory name is returned, else NULL is returned.
