This change adds a new module, opendc-common, that contains
functionality that is shared across OpenDC's modules.
We move the existing utils module into this new module.
|
|
This change adds a new module, opendc-workflow-workload that contains
helper code for constructing workflow simulations using OpenDC.
|
|
This change renames the `opendc-simulator-resources` module into the
`opendc-simulator-flow` module to indicate that the core simulation
model of OpenDC is based around modelling and simulating flows.
Previously, the distinction between resource consumer and provider, and
input and output caused some confusion. By switching to a flow-based
model, this distinction is now clear (as in, the water flows from source
to consumer/sink).

|
This change adds an initial implementation to the trace library for
converting between workload trace formats. Currently the tool supports
only converting to the OpenDC VM trace format. However, in the future,
we will add support for converting between other formats as well.
|
|
This change adds official support to the trace library for the internal
VM trace format used by OpenDC for its experiments. This is a compact
format that uses Parquet to store the virtual machine trace data in two
Parquet files.
|
|
This change adds support in the trace library for the Azure VM trace
format.
|
|
This change creates a new module for doing simulations with virtual
machine workloads. We have found that a lot of code in the Capelin
experiments code is being re-used by non-experiment modules.
|
|
This change removes the energy experiments. The experiments only
provided a setup for the original experiments and is not able to
reproduce the results without further worker.
|
|
This change adds support for reading WfCommons workflow traces in
OpenDC. This functionality is available in the new
`opendc-trace-wfformat` module.
|
|
This change moves the fault injection logic directly into the
opendc-compute-simulator module, so that it can operate at a higher
abstraction. In the future, we might again split the module if we can
re-use some of its logic.
|
|
This change moves the metric collection outside the Capelin codebase in
a separate module so other modules can also benefit from the compute
metric collection code.
|
|
This change updates the WTF trace reader to support the new streaming
trace API.
|
|
This change updates the SWF trace reader to support the new streaming
trace API.
|
|
This change moves Bitbrains trace support into a separate module and
adds support for the new trace api.
|
|
This change extracts the Parquet helpers outside format module into a
new module, in order to improve re-usability of these helpers.
|
|
This change starts the process of moving the different trace formats into
separate modules. This change in particular moves the GWF trace format
into a new module, opendc-trace-gwf.
Furthermore, this change also implements the trace API for the GWF
module.
|
|
This change introduces a new OpenDC API for reading various trace
formats in a streaming manner.
|
|
This change adds a basic framework as basis for network simulation support
in OpenDC. It is modelled similarly to the power system that has been
added recently.
|
|
This change renames the opendc-serverless module to opendc-faas to
better distinguish between the two terms (Serverless and FaaS) and be
clearer about the intent of the module.
The opendc-faas module holds the code for the FaaS platform on top of
OpenDC. Although this is one approach of doing serverless, serverless
can also entail other services that will not be covered by this module.
|
|
This change adds a new module for simulating power components in
datacenters such as PDUs and UPSes. This module will serve as the basis
for the power monitoring framework in OpenDC and will future integrate
with the other simulation components (such as compute).
|
|
This change adds the initial experiment setup for the TensorFlow
on OpenDC experiments.
|
|
This change adds support for the Gradle version catalog feature in our
build configuration. This allows us to have a single file,
gradle/libs.versions.toml, which contains all the dependency versions
used in this project.
|
|
This change updates the build scripts to use type-safe project accessors
when specifying build dependencies between modules.
|
|
This change splits the OpenDC Experiment Harness into separate modules.
This prevents users from pulling in unnecessary dependencies when
depending on the harness API.
|
|
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.
