A classical workflow consists in the following steps:

load some data,
generate a problem from the data,
solve the problem,
compute performance criteria,
display results.

Experiments are then conducted by repeating this task while varying the data, problem parameters, solvers and/or solver parameters. A computer cluster may be used to run all the resulting tasks in parallel, which requires to distribute them adequately among the available resources and then to collect and merge the results.

The package yafe offers a generic framework to conduct such experiments, aiming at saving time and avoiding errors:

the generic framework facilitates the design of experiments,
convenient data structures help to handle results quickly and without confusion between multiple dimensions,
intermediate results can be tracked,
tasks are computed once, even when new tasks are added.
