Service that predicts when hypothetical jobs and when queued jobs will start. Predictions factor job dimensions (space and time) and which system and queue the jobs is submitted to or queued in.
Karnak is a service that predicts job queue wait time for jobs submitted to XSEDE resources. Karnak can provide users either 1) a prediction for when their job will start running, or 2) predictions for how long a hypothetical job would wait in each resource queue before starting on selected XSEDE resources. The latter option can help users decide where to submit their computation within XSEDE.
