From 8aaeb93e81fc3c4689d42747f87734fc4732d030 Mon Sep 17 00:00:00 2001 From: Fabian Mastenbroek Date: Sun, 4 Oct 2020 17:55:26 +0200 Subject: Extract simulation-related code from OpenDC Compute (core) 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. --- .../main/kotlin/org/opendc/compute/core/Flavor.kt | 41 --- .../main/kotlin/org/opendc/compute/core/Server.kt | 78 -----
