Scheduling with Space-Time Soft Constraints In Heterogeneous Cloud Datacenters

Alexey Tumanov
2018
Heterogeneity in modern datacenters is on the rise, in hardware resource characteristics, in workload characteristics, and in dynamic characteristics (e.g., a memoryresident copy of input data).  ...  constraints, (c) combinatorial constraints, (d) orderless global scheduling, and (e) in situ preemption.  ...  Fig. 7.14 evaluates TetriSched and TetriSched-NG (with greedy scheduling instead of global), as a function of the plan-ahead window.  ...

2021 arXiv   pre-print
In our experiments, POP achieves allocations within 1.5% of the optimal with orders-of-magnitude improvements in runtime compared to existing systems for cluster scheduling, traffic engineering, and load  ...  into a global allocation for all clients.  ...  Any opinions and conclusions expressed in this material are those of the authors and do not reflect the views of the NSF.  ...

Hybrid, Job-Aware, and Preemptive Datacenter Scheduling

Pamela Isabel Delgado Borda
2018
Tetrisched uses a reservation system and plans ahead by providing a job the possibility of waiting to get a busy preferred resource or fall back to less preferred options.  ...  Second, we plan to make Kairos handle heterogeneous CPU allocations, where different containers can be allocated different number of cores.  ...  It offers short tasks the possibility of completing with limited or no waiting time, even in high-utilization scenarios.  ...
