model_lock

model_unlock

folder

file name of the lock file containing the process queue

file

Time in hours the top process in the queue is allowed to run
before the current process is stopped.

timeout1

Time in hours the processed is allowed to wait in the queue
before it is stopped

timeout2

Time in seconds between checking the current position
in the queue.

check_interval

a logical indicating whether the script is run on cluster
or not. On windows a lock file is created, which does not prevent
simulatneous access to the model. On the cluster the system command 'mkdir'
is used to prevent simultaneous access. This atomicity of check-and-create
is ensured at the operating system kernel level.

oncluster

process id as returned by model_lock.

Functions that indicate whether a model folder is currently locked by
another process or not. This helps to prevent unintended interactions
between processes.

A collection of tools to create, use and maintain modularized model code written in the modeling
language 'GAMS' (<https://www.gams.com/>). Out-of-the-box 'GAMS' does not come with support for modularized
model code. This package provides the tools necessary to convert a standard 'GAMS' model to a modularized one
by introducing a modularized code structure together with a naming convention which emulates local
environments. In addition, this package provides tools to monitor the compliance of the model code with
modular coding guidelines.
