  We present example applications of an approach to first-principles
calculations of vibrational properties of materials implemented within the
Exabyte.io platform. We deploy models based on the Density Functional
Perturbation Theory to extract the phonon dispersion relations and densities of
states for an example set of 35 samples and find the results to be in agreement
with prior similar calculations. We construct modeling workflows that are both
accessible, accurate, and efficient with respect to the human time involved.
This is achieved through efficient parallelization of the tasks for the
individual vibrational modes. We report achieved speedups in the 10-100 range,
approximately, and maximum attainable speedups in the 30-300 range,
correspondingly. We analyze the execution times on the current up-to-date
computational infrastructure centrally available from a public cloud provider.
Results and all associated data, including the materials and simulation
workflows, are made available online in an accessible, repeatable and
extensible setting.
