This change updates the project structure to become flattened.
Previously, the simulator, frontend and API each lived into their own
directory.
With this change, all modules of the project live in the top-level
directory of the repository. This should improve discoverability of
modules of the project.
|
|
This change adds the trace reader for the serverless experiments as
described in #48.
|
|
This change adds an experiment for the OpenDC Energy project, which
tests various energy models that have been implemented in OpenDC.
|
|
This change removes the event tracer from the repository as we migrate
to the industry standard OpenTelemetry.
|
|
This change integrates the OpenTelemetry Metrics API in the OpenDC
Workflow Service implementation. This replaces the old infrastructure for
gathering metrics.
|
|
This change integrates the OpenTelemetry Metrics API in the OpenDC
Compute Service implementation. This replaces the old infrastructure for
gathering metrics.
|
|
This change adds the initial implementation of OpenDC Serverless to the
main repository, which is based on Soufiane Jounaid's work. This commit
introduces the main interfaces into the repository. Later commits will
introduce the other features that Soufiane has implemented previously in
OpenDC.
|
|
This change adds a generic framework for modeling resource consumptions and
adapts opendc-simulator-compute to model machines and VMs on top of
this framework.
This framework anticipates the addition of additional resource types
such as memory, disk and network to the OpenDC codebase.

|
|
This change removes the opendc-core module. This module was an artifact
of the old codebase and remained mostly unused. This change removes all
usages of the module and if necessary introduces replacement classes.
|
|
This change removes the usage of bare-metal provisioning from the OpenDC
Compute module. This significantly simplifies the experiment setup.
|
|
This change moves the bare-metal provisioning packages outside the
compute module since these modules represent different layers in the
ecosystem and should not be mixed.
|
|
This change introduces the ComputeService interface (previously
VirtProvisioningService) and provides a central implementation in
opendc-compute-service.
Previously, the implementation of this interface was bound to the
simulator package, which meant that independent business logic could not
be re-used without importing the simulator code.
|
|
This change extracts the API for the OpenDC Compute service into a separate
module to establish a clearer boundary between the interface meant for
consumers and interfaces meant for the the serve implementation.
|
|
This change uses the Java Platform functionality from Gradle to enable
shared dependency constraints across modules.
|
|
|
|
This change adds an experiment harness to OpenDC 2.0 based on previous
work on separate branches. This harness enables users to declaratively
specify and orchestrate experiment designs.
|
|
This change adds a new library for event tracing, in order to use a
consistent approach for recording and processing event (streams).
|
|
|
|
This change splits the opendc-compute module into two modules:
1. opendc-compute-core
The interfaces and APIs that represent a IaaS platform.
2. opendc-compute-simulator
The implementation of these interfaces using simulation components
from opendc-simulator-compute.
|
|
This change adds an opendc-simulator-compute module which contains
interfaces related to simulating compute workloads. For future changes,
we intend to decouple the simulation part from the opendc-compute
module.
|
|
This change moves the OpenDC modules previously living in the simulator/opendc
directory to the simulator directory itself given that we do not make a
distinction between OpenDC and odcsim anymore.
|
|
This change removes the odcsim components from the repository as we have
eliminated their use in the OpenDC codebase, by replacing them with the
more generic (Test)CoroutineScope and Clock. From now on, we will only
place modules under the OpenDC namespace and not use odcsim as well to
prevent confusion.
|
|
This change moves the custom Flow object we provide (e.g. EventFlow and
StateFlow) outside of the odcsim-api module into a separate opendc-utils
module.
This is in preparation for the removal of the odcsim components in OpenDC.
|
|
This change introduces a new module in the OpenDC namespace where
simulation-specific code will be placed. We will move away from the
odcsim naming to prevent getting confused users due to this complex
naming scheme.
Furthermore, this module will live in the org.opendc package instead of
the com.atlarge.opendc to further reduce depth of the packages.
|
|
|
|
This change prepares the simulator Git repository for the monorepo residing at
https://github.com/atlarge-research.com/opendc. To accomodate for this, we
move all files into a simulator subdirectory.
