ec18b617da ignored error returned from LaunchTasks. Technically, this error shouldn't occur. Retrofitted scheduling policies to not receive an error when calling LaunchTasks(...) 2018-09-23 18:30:12 -04:00

f041e6668b added a baseSchedPolicyState struct in schedulers/schedPolicy.go. This struct would store information common to scheduling policies. Added member called numTasksScheduled to baseSchedPolicyState that would keep count of the number of tasks that the current scheduling policy has scheduled. Moved the logic to switch (currently performing a random switch) to baseSchedPolicyState#switchIfNecessary(...) and retrofitted all scheduling policies to call this instead of inlining the code in each of them. 2018-09-23 18:28:11 -04:00

435c4ca1bc fixed bug in schedWindow resizing strategy, where earlier it was stopping after checking if the first task in the queue can be scheduled in the next offer cycle. Changed baseScheduler to store the schedWindowResizingStrategy instead of the criteria. Retrofitted the scheduling policies to use the scheduling window resizing strategy directly from baseSchedRef. 2018-09-23 18:10:02 -04:00

3ebd7b0c7e added utility to compute the scheduling window. Right now there's only criteria on which this is determined -- fillNextOfferCycle. So, the schedWindow is the max number of tasks, that aren't yet scheduled, whose aggregate resource requirement is as close as possible to the resource available in the next round of resource offers. To be able to make the most use of the next offer cycle, one would need to perform a non-polynomial search of the TaskQueue and as this is computationally expensive, a linear search is performed on the TaskQueue. Retrofitted scheduling policies to also call utilities.schedUtils#schedWindowResizingStrategy#Apply before switching to a new scheduling policy. 2018-09-23 18:03:14 -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

065705d480 Merged in experimentation/schedPolicySwitcher (pull request #1) 
Experimentation/schedPolicySwitcher
1. Initial commit for consolidated loggers using observer pattern.
2. class factory for schedulers.
3. Using the scheduling policy class factory in schedulers/store.go and the scheduler builder helpers in schedulers/helpers.go, feature to be able to be able to plug a scheduling policy of your choice from the command line (right now only first-fit and bin-packing are possible. Will be updating the class factory to include other scheduling policies as well.
4. Removed TODO for using generic task sorters. Modified TODO for a config file input to run electron.
5. Added other schedulers to the factory
6. Partially retrofitted the other scheduling policies to use the logging library.
7. Retrofitted extrema and progressive to use the consolidated logging library. Fixed parameter issue with s.base.Disconnected(). Formatted project
8. Move statusUpdate(...) into base.go to remove redundant code.
9. Converted the baseScheduler into a state machine where the state is a scheduling policy that defines an approach to consume resource offers.
10. Added another command line argument to be used to enable switching of scheduling policies. Retrofitted scheduling policies to switch only if the particular feature has been enabled.

changed argument to coLocated(...) to take base type rather than ElectronScheduler type. Also, prepended the prefix to the directory of the logs so that it would be easier to determine what the files in a directory correspond to without viewing the contents of the directory.
Defined methods in ElectronScheduler. Each of these methods corresponds to a type of log that an ElectronScheduler would make. Each of these methods would need to be implemented by the scheduling policy.

Electron has only one scheduler that implements the mesos scheduler interface. All the scheduling policies are just different implementations of ways to consume mesos resource offers. Retrofitted scheduling policies to now embed SchedPolicyState instead of baseScheduler.
