* Updated SimTrace to use a single ArrayDeque instead of three separate lists for deadline, cpuUsage, and coreCount * Renamed input files to tasks.parquet and fragments.parquet. Renamed server to task. OpenDC nows exports tasks.parquet instead of server.parquet
* Fixed a problem which caused the CPU limit to be much lower than it should be. AllocationPolicy is now properly exposed to the user * Fixed tests * spotless kotlin
* Updated the topology format to JSON. Updated TopologyReader.kt to handle JSON filed. Added documentation for the new format. * applied spotless kotlin * small update * Updated for spotless apply * Updated for spotless apply
* Updated all package versions including kotlin. Updated all web-server tests to run. * Changed the java version of the tests. OpenDC now only supports java 19. * small update * test update * new update * updated docker version to 19 * updated docker version to 19
* removed experiment-compute and integrated all components into opendc-compute * updated workflow gradle file * removed unneeded code
* made sure all tests run * fixed typo * executed spotlessApply * added back web-server tests * updated SimTraceWorkloadTest * commented CapelinRunneer and GreenifierRunner tests * commented one SimTraceWorkloadTest * altered codecov execution * changed codecov
This change replaces the use of `CoroutineContext` for passing the `SimulationDispatcher` across the different modules of OpenDC by the lightweight `Dispatcher` interface of the OpenDC common module.
This change updates the `SimulationScheduler` class to implement the `Dispatcher` interface from the OpenDC Common module, so that OpenDC modules only need to depend on the common module for dispatching future task (possibly in simulation).
This change updates the implementation of `SimHost` to use workload chaining for modelling boot delays. Previously, this was implemented by sleeping 1 millisecond using Kotlin coroutines. With this change, we remove the need for coroutines and instead use the `SimDurationWorkload` to model the boot delay. In the future, we envision a user-supplied stochastic boot model to model the boot delay for VM instances.
This change re-implements the OpenDC compute simulator framework using the new flow2 framework for modelling multi-edge flow networks. The re-implementation is written in Java and focusses on performance and clean API surface.
