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 converts the Server data class which can be used as a
stateful object to control an instance running in the cloud.
|
|
This change refactors the OpenDC Compute module so that the
VirtProvisioningService is now responsible for managing the lifecycle of
Server objects as opposed to the VirtDriver and BareMetalDriver
previously.
|
|
This change separates the cloud compute layer in OpenDC (e.g., Server)
from the bare-metal layer (e.g., Node), such that Node and
BareMetalDriver are unaware of the existence of Server and co.

This commit implements the energy models that are present in CloudSim:
1. Constant
2. Linear
3. Cubic
4. Square root
5. Interpolation based on data.

This change adds a timeout for experiments that are run by the web
runner in order to prevent buggy/long simulations from consuming one of the
CPU cores forever.

|
|
|
This change eliminates the large Spark dependencies from the web runner.
Instead, we perform on the fly aggregation of the data and report
directly to MongoDB.

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 updates the remainder of the codebase to use the
opendc-simulator-compute module for the simulation of workloads.
|
|
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 adds explicit visibility modifiers to the public interfaces
and enables Kotlin 1.4's explicit API mode.
|
|
This change moves the OpenDC simulator codebase to the org.opendc
namespace of which we control the domain. Previously, we used the
com.atlarge package of which we did not control the domain, which might
lead to difficulties in the future.
|
|
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.
