c31bf8db01 BUG Fix1: taskID creation in taskUtils#initTaskResourceRequirements. BUG Fix2: Converted value in utilities/trackResourceUsage#TrackResourceUsage#perHostResourceAvailability to be a pointer to ResourceCount. 2018-09-23 17:46:38 -04:00

657dc8df93 Track resource usage across the cluster. Created utility in utilities/ to track the total and the unused resources for each host in the cluster. Added utility to def/taskUtils.go to retrieve the resource requirement for a given taskID. Decoupled the code, to launch a list of tasks on a set of offerIDs, to schedulers/helpers.go and updated all the scheduling policies to call this function instead of directly calling mesos.SchedulerDriver#LaunchTasks. The resource availability of the cluster is updated at 2 stages -- 1. When the tasks are about to be launched (in schedulers/helpers.go#LaunchTasks), the scheduling policy switching logic will be able to adhere to the update in the resource availability due to the JUST launched tasks and 2. when a terminal status update is received for a task (in schedulers/base.go#statusUpdate). 2018-09-23 17:44:36 -04:00

9e620eaede changed def.TaskSorter(...) to def.SortTasks(...) for semantics. Now, def.SortTasks(...) also sorts the tasks instead of returning just a func (i, j int) bool {}. Removed TODO from the README associated with this PR 2017-08-26 15:39:45 -04:00

0869bea2d8 Used closures instead of strings for the generic sorter. This removed the need for reflection. 2017-08-26 15:19:30 -04:00

f29b7f51a9 Added a generic task sorter utility. This allows for an array of tasks to be sorted based on any resource. The possible resources by which an array of tasks can be sorted currently are listed in def/sortingCriteria.go. One can add more to this if required. 2017-08-23 19:35:19 -04:00

f4459c8cbf Consolidated the ClassifyTasks(...) functions from topHeavy and bottomHeavy and added the function to def/taskUtils.go. Added TODOs for refining the means by which the kmeans classified clusters were sorted. 2017-08-22 13:00:40 -04:00

74eb616a72 the observation that is to be considered for the classification of a task can now be given as a function that takes the task and returns the observations as a slice of float64. Retrofitted the other functions in taskUtils to make use of this feature. 2017-02-25 19:57:01 -05:00

e54697b0dc Added a task utility to be able to cluster tasks into N clusters based on their watts resource requirements. Electron now compatible with Go1.8 and no longer with 1.7. Added TODOs. 2017-02-25 15:43:32 -05:00
