OpenDC v2.2b

OpenDC 2.2b extends both the input and the output of OpenDC.

The topology.json file now also accepts strings instead of numbers. When using strings as an input, the user can specify the unit of the value. See #242 for more info.

A user can now specify which columns should be exported by OpenDC. This can be useful when running large experiments. See #241 for more information.

RaDiCe: A Risk Analysis Framework for DataCenters

This release contains the code and data artifacts used to produce the paper "RaDiCe: A Risk Analysis Framework for DataCenters".

OpenDC v2.0

This is the second major release of OpenDC, the open-source datacenter simulation platform. Version 2 of OpenDC enables convenient modeling and simulation of existing and emerging technologies in cloud datacenters.

We started work on OpenDC in 2017, with a great plan and unique vision. We put in total 4 years of science, design, and engineering to reach this point.
OpenDC 2.0 supports workflows, serverless and cloud computing operations, Big Data and machine learning workloads, virtualization and bare-metal datacenters. OpenDC can solve problems of short-term decision making, such as scheduling and auto-scaling, and also, through the Capelin extension, of long-term capacity planning and procurement.
